RESIN-BASED COMPOSITE STRUCTURE AND METHOD FOR FORMING THE SAME
A method for forming a resin-based composite structure is provided. The method includes: providing a prepreg layup, wherein the prepreg layup includes an epoxy resin-carbon fiber composite material; covering a thermal-fusion material on a surface of the prepreg layup; and performing a molding and curing process to fuse the thermal-fusion material with the prepreg layup. Wherein the molding and curing process includes: heating at a first temperature to melt, soften and fully fuse the thermal-fusion material with the prepreg layup; and heating at a second temperature to solidify the thermal-fusion material for forming the resin-based composite structure. Wherein the first temperature is lower than the second temperature.
ASYMMETRICAL STRETCH COMPOSITE FOR PIPE LINER
A fibrous material or composite including a plurality of layers joined to one another, for example, by needlepunching, is disclosed. The fibrous composite generally has an asymmetrical stretch profile, such that the fibrous composite is more extensible in the cross-machine direction than in the machine direction. The fibrous composite may find particular use in forming a cure-in-place pipe liner.
Corrosion inhibiting sprayable thermoplastic cover for mechanical assemblies, and methods of making and using
A Corrosion Inhibiting Sprayable Thermoplastic (CIST) cover is formed by spraying melted CIST onto a mold, allowing the CIST to cure, removing the cured cover from the mold using a series of cuts if necessary, positioning the cover on a mechanical assembly whose shape is significantly identical to the mold, and fusing the cuts on the cover using heat to reform the cover on the mechanical assembly.
FLUOROPOLYMER PIPE
The present invention pertains to a pipe comprising at least one layer at least comprising, preferably consisting essentially of (or being made of), a tetrafluoroethylene (TFE) copolymer comprising from 0.8% to 2.5% by weight of recurring units derived from at least one perfluorinated alkyl vinyl ether having formula (I) here below:
CF.sub.2CFOR.sub.f(I)
wherein R.sub.f is a linear or branched C.sub.3-C.sub.5 perfluorinated alkyl group or a linear or branched C.sub.3-C.sub.12 perfluorinated oxyalkyl group comprising one or more ether oxygen atoms,
said TFE copolymer having a melt flow index comprised between 0.5 and 6.0 g/10 min, as measured according to ASTM D1238 at 372 C. under a load of 5 Kg [polymer (F)].
The invention also pertains to use of said pipe in heat exchangers and in downhole operations including drilling operations.

Processes for collation shrink packaging with a thermally insulating film
This invention relates to processes for collation shrink packaging of one or more items with a thermally insulating film, to films for such processes, to packages so made, and to methods for extruding such films. The one or more items packaged may be cans, bottles, pouches and other carriers of liquid or solids.
Assembly with temporary protective film
The invention relates to a composite comprising (i) a plastics component or (ii) a semifinished plastics product with a protective layer system, where the protective layer system comprises a plastics film and an organosilicon plasma polymer layer, the organosilicon plasma polymer layer is arranged between the (i) plastics component or the (ii) semifinished plastics product and the plastics film and, after the hardening of the (i) plastics component or of the (ii) semifinished plastics product, the organosilicon plasma polymer layer adheres more securely to the plastics film than to the (i) plastics component or the (ii) semifinished plastics product.
METHOD AND APPARATUS FOR COATING SOLID WOOD FLOOR AND SOLID WOOD FLOOR
A method and an apparatus for coating a solid wood floor and a solid wood floor are provided. The method for coating a solid wood floor includes providing a solid wood floor, where the solid wood floor has two side surfaces defining boundaries of a width dimension of the solid wood floor; and providing a polyethylene protective film, and adhering the polyethylene protective film to at least one of the two side surfaces. Therefore, external moisture can be prevented from entering the solid wood floor so as to avoid deformation of the floor due to moisture; an external dust, water, etc. can be prevented from entering between two adjacent solid wood floors; an overall appearance of the laid solid wood floors will not be affected by the coating; when the laid solid wood floors are subjected to force, no noise will be emitted, thereby improving customer satisfaction.
LAMINATING MACHINE, LAMINATING METHOD, AND MANUFACTURING SYSTEM FOR HEAT-INSULATING CARDBOARD
A laminating machine, laminating method, and manufacturing system for heat-insulating cardboard are provided, featuring a high degree of automation to increase manufacture efficiency. The laminating machine includes: an adhesive-applying mechanism (1) having a cardboard-pressing roller (11) and a first adhesive-applying roller (12) that are vertically aligned and form a gap therebetween through which cardboard (10) can be friction-fed; and a laminating section (2) downstream of the adhesive-applying mechanism (1) and having upper and lower pressure rollers (21, 22) that are vertically aligned and form a gap therebetween through which the cardboard (10) can be friction-fed, with a second adhesive-applying roller (23) provided near the lower end of the lower pressure roller (22) and forming a gap therewith through which a heat-insulating material (20) can be friction-fed in order to be rolled onto and adhesively bonded to the lower surface of the cardboard (10) by the lower pressure roller (22).
Manufacturing method of tank
A manufacturing method of a tank comprises winding a fiber on a liner by hoop winding. The winding comprises: forming an (N+1)-th layer such that a position closer to a center of the liner by a first predetermined distance along an axis line direction of the liner from an end in the axis line direction of an N-th layer is set to position of an end in the axis line direction of the (N+1)-th layer with respect to a direction perpendicular to the axis line direction; and winding the fiber on the N-th layer to provide one winding turn of the fiber, such that a pressing force of pressing the N-th layer in the axis line direction by the fiber is equal to or smaller than a total frictional force in an area in the N-th layer on an edge side in the axis line direction of a fiber winding position.
