A process for compression molding a fiber reinforced thermoplastic resin article that includes subjecting the fiber reinforced resin material to heat and pressure to form the article, then directionally cooling the mold sequentially from bottom to top to provide a thermal gradient suitable for creating directional solidification of the material.

Compression molding of structures

A fiber reinforced composite matrix that includes one or more layers of unidirectional fibers alternated with one or more layers of a porous fibrous material, all the fibers being embedded in a thermoplastic resin.

Fiber reinforced composites comprising uni-directional fiber layers and

A composite comprising a fluoropolymer resin matrix reinforced with continuous filament aligned fibers for use in corrosive high temperature environments.

Structural composites of fluoropolymers reinforced with continuous

A fiber reinforced material is made by passing a preheated tensioned filament array over an arcuate extruder head where thermoplastic polymer is flowed through the filament array to expel air from the array while coating the filaments with polymer. The filaments comprise 50 to 75 percent by volume of the material and the polymer has a relative viscosity of at least 50.

Method for producing fiber reinforced thermoplastic material

Fiber reinforced thermoplastic material

A composite reinforced with polycrystalline alumina fibers in a matrix of an aluminum alloy containing 0.5-5.5% by weight of the matrix of lithium is prepared by infiltrating alumina fibers with a molten alloy containing aluminum and 1-8% by weight of lithium for a time sufficient to form a reaction sheath on the fibers of a thickness less than about 15% of the total fiber diameter.
