Abstract
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.
