DETAILED DESCRIPTION OF THE INVENTION

[0046] The present invention as described below, it is to be understood that this invention is not limited to particular embodiments, drawings, methodologies and materials described, as these may vary as per the person skilled in the art. It is also to be understood that the terminology used in the description is for the purpose of describing the particular embodiments only, and is not intended to limit the scope of the present invention.

[0047] Before the present invention is described, it is to be understood that unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs.

[0048] Further, it is to be understood that the present invention is not limited to the methodologies and materials similar or equivalent to those described herein can be used in the practice or testing of the present invention, the preferred methods and materials are described, as these may vary within the specification indicated. Unless stated to the contrary, any use of the words such as including, containing, comprising, having and the like, means including without limitation and shall not be construed to limit any general statement that it follows to the specific or similar items or matters immediately following it. Embodiments of the invention are not mutually exclusive, but may be implemented in various combinations. The described embodiments of the invention and the disclosed examples are given for the purpose of illustration rather than limitation of the invention as set forth the appended claims. Further the terms disclosed embodiments are merely exemplary processes of the invention, which may be embodied in various forms.

[0049] It is also to be understood that the terms a, an, the and like are words for the sake of convenience and are not to be construed as limiting terms. Moreover, it will be understood that the illustrations are for the purpose of describing a particular exemplary embodiment of the invention and are not limited to the invention thereto.

[0050] The term fibres or fibre or fabric or fabrics are interchangeable and intend to cover single as well as plural fibre or fabric.

[0051] In many vehicular applications, fuel economy is a function of vehicle weight. It is desirable, therefore, to reduce the weight of glazings for such applications without compromising strength, sound-attenuating properties and weather ability. In this regard, it can be advantageous for a glass laminate to be mechanically robust with respect to external impact events such as attempted forced entry or contact with stones or hail, yet suitably dissipate energy (and fracture) as a result of internal impact events such as contact with an occupant or any collision. Further, governmental regulations are demanding higher fuel mileage and lower carbon dioxide emissions for road vehicles. Thus, there has been an increased effort to reduce the weight of these vehicles while maintaining current governmental and industry safety standards. Non-glass window materials, such as polycarbonate, have been developed, which reduce vehicle weight but do not offer appropriate resistance to environmental, debris, and other concerns. Also, degree of inclination has direct impact on thickness variations and curing mechanisms of the resin. More inclined charging of resin results in bulging of resin at the centre part of the mould and uncontrolled process due to leakage problem. Higher inclination leads to faster curing and high exothermic reaction.

[0166] The products A1 to A3, B1 to B3, C1 to C3 and D1 to D3 were made by using treated and untreated glass at different degrees of inclination. The charging of resin is executed by maintaining different degrees of inclination i.e. 5 to 15 degree. Degree of Inclination has direct impact on thickness variation and curing mechanisms of the resin. The charging of resin at more inclination results in bulging of resin at the centre part of the mould and uncontrolled process due to leakage problem. Higher inclination leads to faster curing and high exothermic reaction. Degree of inclination and surface treatments imparts effects on various properties of glass as shown in Table-1. A1, B1, C1, and D1 has shown excellent results like low heat of reaction, high transmittance in visible light I/I.sup.0 (a.u), low Surface Indolence and low Air bubble. A2, B2, C2, and D2 has shown excellent results like low heat of reaction, high transmittance in visible light I/I.sup.0 (a.u), low Surface Indolence and low Air bubble as well as we have not observed problem of bulging of resin at the central part of the mould while charging resin at 10 inclination, leakage and process of charging and curing was well controlled. A3, B3, C3, and D3 has shown satisfactory results of heat of reaction, transmittance in visible light I/I.sup.0 (a.u), moderate Surface Indolence and moderate Air bubble.

[0208] A moulded laminated reinforced composite glass product J2 having a cross section 81000 of length 1000 mm was developed.

[0209] A nano composite was created by adding 100 phr of epoxy (supplied by Atul Chemicals Pvt. Ltd. and having 50% epoxy resin and 50% hardener), 0.7% of nano clay, 4% of polyurethane and 2% of polyvinyl ester followed by sonication. This example used the above mentioned nano composite liquid system.

[0210] 6 mm Toughened glass treated by dipping with polyvinyl acetate was used here. The said treated glass sheet being upper glass sheet (108) was placed at predefined distance over another said treated glass sheet being lower glass sheet (108). These glass sheets were separated by placing 10 mm thick cross-linked polyethylene foam of 20 mm width as spacers (109, 109) and thus sealed to obtain a predefined size mould (103). The mould assembled (103) was placed on a actuated platform (106) in angular motion. The degree of inclination of the said platform was controlled by using hydrolytic actuation mechanism (107). The nano composite liquid system which was previously sonicated, was charged into a hopper (100) having foldable flat base so as to degas the nano composite liquid system. After degassing the nano composite liquid system, the said foldable flat base of said hopper (100) was converted into an accumulator further allowing the flow of the degassed nano composite liquid system through the resin inlet (101) flat tube (102) into mould assembly (103) to completely fill mould i.e. gap between upper and lower glass sheets. The said actuation platform (106) was operated at 10 degree of inclination from ground. The nano composite liquid system was discharged into the mould (103) under gravity at 10 degree of inclination.

[0211] The said nano composite was allowed to gel and chilled air was passed over the said mould (103) to obtain moulded laminated reinforced composite glass. Transmittance in visible light I/I.sup.0 (a.u) and bonding between glass and resin of the product were checked and observations were tabulated in Table 3.

[0220] Epoxy, Polyurethane and Polyvinyl acetate surface coating improved bonding between glass and resin. Thick and flexible coating on glass surface is more vulnerable in holding cure resin on breakage of the product wherein rigid and thin coating holds resin profoundly. Table-3 shows thin flexible coating on top of treated glass surface holds thin glass broken fragment glass but reduces transparency to satisfactory level.

A Moulded Laminated Reinforced Composite GlassL1

[0221] A moulded laminated reinforced composite glass product L1 having a cross section 201000 of length 1500 mm was developed.

[0222] A nano composite was created by adding 100 phr of polyester (supplied by Satyen Polymer. Pvt. Ltd.), 2% of cobalt octoate, 1.5% of methyl ethyl ketone peroxide (MEKP), 0.1% of carbon nano tube, 0.3% of nano clay, 5% of epoxy resin, 3% of vinyl acetate followed by sonication. This example used the above mentioned nano composite liquid system.

[0223] 3 mm ordinary glass treated by dipping with amino isopropyl ethoxy silane (AIES) was used here. The said treated glass was subjected to devolatilization. A cross linked polyethylene foam being upper support was placed in close contact with upper plate (12) in said mould assembly (5) followed by placing said treated glass sheet being upper glass sheet over said upper support. The spacers (11) were placed over to cover all edges of the said upper treated glass sheet. Further, a bi-directionally pre-tensioned synthetic E-glass fabric of 80 GSM (supplied by Woon's Corning) was placed over spacers (11). Again spacers (11a) were placed over covering all edges of the said fabric followed by placing said treated glass sheet being lower glass sheet over the said spacers (11a). A cross linked polyethylene foam being lower support was placed over said lower treated glass sheet and in close contact with said lower plate (12) in mould assembly (5). Thus, said upper and lower plate including support, glass and synthetic fabric were placed apart by spacers (11, 11a) by placing spacers (11, 11a) at each of the four edges between them. Each spacer (11, 11a) had guide pin at one end and pin hole at other end. Three spacers were placed at three edges of said fabric at both side and were interconnected through the guide pin and the pin hole mechanism to form three equidistant hinges. Fourth spacer (11) had one pin lock at the edge and placed at the fourth edge of the said fabric at both side and lock and seal the mould assembly (5). The said spacers (11, 11a) were pre-designed to accommodate the said plates including support, glass and synthetic fabric on atop of it and closely engaged along with plates including support, glass and synthetic fabric through the guide pin and the pin hole mechanism. The said mould assembly was actuated by hydraulic actuation mechanism into the vacuum chamber by applying vacuum pressure 200 mbar and checking leakage as well as removing air. The above-mentioned nano composite liquid system (i.e. nano dispersed liquid system) was casted on the hopper of foldable flat base and was allowed to stand for 60 sec to degas said composite liquid system. The said hopper of foldable flat base was converted into accumulator containing said degassed nano composite liquid system. The said degassed nano composite liquid system was charged into said mould assembly from said accumulator through a resin inlet using a control valve. The level of said composite liquid system in a resin outlet was monitored through window and once it reached to the marking level of resin outlet (17), then the flow of said nano composite liquid system into said mould assembly was stopped by using controlling valve (16). The said composite liquid system in the said mould assembly was allowed to gel for complete gelling followed by shutting off the actuation mechanism by releasing vacuum. Chilled air was passed through said mould assembly to reduce heat generated by exothermic reaction followed by removing moulded laminated reinforced glass. The said moulded laminated reinforced glass was tested for Bending strength (N/mm.sup.2), Transmittance in visible light I/I.sup.0 (a.u), Surface Indolence (mm), Ballistic 80 m/s speed (3J), and Air bubble. The results of the same were tabulated in Table 4.

[0239] The cured moulded laminated reinforced composite glass was tested for density, glass to resin bond strength, tensile, drop impact and flexural properties. These tests showed that the composites glass possessed good physical and mechanical properties. The new composite glass has applications in windshields, windows and other components where a strong, lightweight transparent material is desirable. The moulded laminated reinforced composite glass will also have potential applications as backing material in transparent armour systems. The cured composite glass is low density product as compared to normal glass. Also, the laminated composite glass of the invention has improved glass to resin bond strength which helps to hold the glass fragments upon breakage. The laminated composite glass has excellent weather ability or environment resistance and has excellent laceration property as compared to normal composites glass. Thus the present invention provided a moulded laminated reinforced composite glass which is very durable, higher mechanical properties compared to conventional glass and heat insulative yet very light in weight. The present invention also provides a process of producing the same in very simple and economic manner by using very less expensive glass as a starting material and various easily available resins. The present invention has achieved the superior traits of the final product of the present invention as compared to conventional products based on the following:

1. Vacuum assisted resin discharge;
2. Low GSM glass fabrics;
3. Pretension of fabrics increases the compressive load bearing of glass;
4. Higher GSM fabrics reduces the transparency;
5. Higher GSM fabrics increases the tensile and flexural strength;
6. Low heat generation and slow curing is desirable;
7. Higher vacuum reduces the bubble formation; and
8. Resin discharge under gravity, low degree of inclination facilitates low heat generation and formation of micro air bubbles.
