An impact resistant rigid composite article comprising a fibrous layer comprising a network of filaments dispersed in a rigid matrix comprising one or more thermosetting resins and one or more thermoplastic resins which preferably include one or more initiating/compatibilization agents.

Ballistic resistant composite article having improved matrix system

An article made from at least one network of high strength fibers and a matrix composition that includes a vinyl ester and diallyl phthalate. Preferably, the article is made from at least one prepreg element which includes at least two adjacent layers of the high strength fiber network in the vinyl ester-containing matrix composition. The prepreg element is made by applying a mixture of vinyl ester, diallyl phthalate and a carbon-carbon saturated solvent to the high strength fiber network.

High strength composite

An article which includes at least one layer of a network of high strength fibers, preferably extended chain polyethylene fibers. The fibers of the network are coated with a very low modulus elastomeric matrix material, preferably an acrylic ester copolymer, which has a tensile modulus of less than about 100 psi, a tenacity of less than 450 psi (3105 kPa), a glass transition temperature (T.sub.g) of about -10.degree. C. to about -20.degree. C., and an elongation-to-break of at least about 2000%. The article can further include a second matrix material, preferably made of polyethylene, adjacent to the fiber network layer.

Soft armor composite

An impact resistant rigid composite article comprising a fibrous layer comprising a network of filaments dispersed in a rigid matrix comprising one or more thermosetting resins and one or more thermoplastic resins.

Ballistic resistant composition article having improved matrix system

An essentially tack free prepreg article, characterized by a shelf life at about 25.degree. C. of at least about three months, and method of making the same are provided. The prepreg article comprises at least one network of fibers which has been impregnated with a solution of a resin in styrene and a catalyst. The resin is curable by the catalyst at a temperature above about 90.degree. C. The impregnated network is dried for a length of time and at a temperature sufficient to reduce the styrene content to less than about 1% by weight of the impregnated network without curing the resin. The prepreg article can subsequently be used as a component in a molded composite.

Extended shelf life prepreg article and method

This invention relates to optimum formulation regions of reinforced thermosetting resin composites incorporating substantially increased filler loadings which have been found to retain the impact strength of formulation regions with substantially less filler loadings. The reinforced thermosetting resin composite of this invention comprises

Optimum formulation regions of reinforced thermoset composites

Large diameter filaments are produced by increasing the cooling efficiency of a molten polymer as it exits a spinnerette orifice. The cooling is accomplished in a collar configuration having means for directing cooling air and an ionic discharge in a direction transverse to the axis of the filament as it passes through the collar.

The invention relates to polyester resin modified with hydantoin diacid or hydantoin diol and cyclohexyl diethanolamine. The copolyesters are dyeable with acid type dyes to form brightly colored fibers and fabrics.

Acid dyeable polyesters

Polyethylene terephthalate block copolyesters having ethylene terephthalate blocks and hydantoin polymer blocks for improved disperse dyeability and improved antistatic properties. The copolyesters are prepared by conventional methods using blocks of low molecular weight polyethylene terephthalate and hydantoin polyester.
