A polyurethane based filament winding resin reaction mixture, a resin bath and a filament winding apparatus are set forth. The reaction mixture comprises an isocyanate component including one or more isocyanates and an isocyanate-reactive component including from 5 wt % to 95 wt % of one of more polyols having a number acerage molecular weight from 50 g/mol to 8,000 g/mol, from 2 wt % to 30 wt % of one or more propane based triols, and from 1 wt % to 15 wt % of one or more trimester-phosphates, based on the total weight of the isocyanate-reactive component. A ratio of a total weight of the one or more propane based triols to a total weight of the one or more trimester-phosphates is between 1.1 and 5.0.

The present invention relates to a one-part, textile-reinforced molded hose (1) having at least one bend along its extension in a hose longitudinal direction (4a), in particular a sealing hose for sealing a screen with respect to a holding frame of a vibrating screen apparatus for separating solids from a mixture of liquid and solids, and to a method for producing the molded hose (1), a vibrating screen apparatus and a vehicle used in public transportation, each having such a sealing hose, and to the use of the molded hose as such a sealing hose.

The present invention relates to a method for producing a needle punch carpet having a velour-type and more wear-resistant surface which has advantageous characteristics over conventional flat needle nonwovens and dilour carpets.

A fiber sizing agent includes: a vinyl ester resin (A) having an alkoxy polyoxyalkylene structure and a urethane bond; and an aqueous medium. The fiber sizing agent has excellent fiber sizing properties for various fibers such as glass fibers and carbon fibers. A molded article obtained from a molding material including the fiber sizing agent is excellent in various physical properties such as bending strength, compressive strength, and interlaminar shear strength, and thus can be used, for example, for an automobile member, an aircraft member, a windmill member, and an industrial member.

Fabrication of ballistic resistant fibrous composites having improved ballistic resistance properties. More particularly, ballistic resistant fibrous composites having high interlaminar lap shear strength between component fiber plies or fiber layers, which correlates to low composite backface signature. The high lap shear strength, low backface signature composites are useful for the production of hard armor articles, including helmet armor.

Disclosed herein are fiber-reinforced composites. These materials are useful in load-bearing components for mechanical systems, and other applications. Also disclosed herein are methods of making and using such composites, articles comprising the same, and the like. For example, some embodiments of the invention are generally directed to composites comprising discontinuous agents such as fibers or platelets which are positioned within a substrate, e.g., formed from a plurality of continuous fibers. In some cases, the discontinuous agents may be substantially aligned, for example, by attaching magnetic particles onto the agents and using a magnetic field to manipulate the agents. Other embodiments are generally directed to systems and methods for making or using such composites, kits involving such composites, or the like.

A fiber-reinforced composite material, consisting of an amorphous thermoplastic matrix distributed over a surface of an aramid fabric and forming a surface thermoplastic film partially interpenetrated with and adhering to the aramid fabric. The production method comprises the steps of: unwinding an aramid fabric on conveyor means; distributing a thermoplastic matrix in the form of micrometric powder over the whole upper surface of the aramid fabric as it is unwound; passing the material through a first hot section and then through a second relatively cold section; the first section applies a temperature and a pressure such as to form a surface thermoplastic film on the fabric; the second section facilitates detachment of the coated material from the conveyor means. The plant comprises a conveyor belt on which an aramid fabric is unwound; a powder scattering station adapted to distribute a thermoplastic matrix in the form of micrometric powder on the aramid fabric as it is unwound on the conveyor belt; a system of double belts in contact through which the fabric is conveyed; the system of double belts in contact defines a first hot section and a second relatively cold section; the first section applies a temperature and a pressure functional to the formation of a surface thermoplastic film on the fabric; the second section facilitates detachment of the fabric.

This disclosure relates to a sewing process of a breathable, reusable, and leak-proof garment multilayered-lining having absorbent, antimicrobial, waterproofing, and steam dispersion functions. Such lining aims at preventing body fluids such as sweat, blood, vaginal fluids, menstrual fluid, urine, breast milk, or post-surgical fluids from leaking. Such a lining provides the absorbent, antimicrobial, waterproofing, and steam dispersion functions. The lining may be sewed or adhered to the garment piece including: men's and women's underwear, shorts, short pants, skirts, pants, bras, shirts, T-shirts, jumpsuits, body shapers, dresses, men's and women's nightwear, etc. The sewing process creates channels for the liquid and creates a non-linear U-shaped structure on the lining to prevent leakage from the sides. The disclosed lining also has a reduced number of layers on its sides due to one of its layers being smaller in width than the other layers, making the coating thinner for the wearer.
