Abstract
A filament winding process is disclosed for producing articles having a layer of wound helically extending fibers sandwiched between generally longitudinal fibers. The process is well adapted for use with thermoplastic resins and for producing articles having a high resistance to bending. In a preferred embodiment, there is disclosed a filament wound baseball bat formed from a thermoplastic resin, (poly(arylene sulfide).
Claims18
A filament wound article having a longitudinal axis, and a body portion and a neck portion positioned along the longitudinal axis, said filament wound article characterized by a laminated outer shell of layers of fiber reinforcement in the form of fiber rovings impregnated in a continuous resin matrix, said laminated outer shell being characterized by a layer of generally helically extending rovings of said fiber reinforcement which form an angle of from near 0.degree. to near 90.degree. with a plane normal to the longitudinal axis of the filament wound article sandwiched between at least two layers of rovings of said fiber reinforcement lying generally in planes which include the longitudinal axis of the article.
