Abstract:
A method of fabricating a composite drain cover, comprising the steps of:inserting a plurality of reinforcement layers into a mold having a cavity, each of said reinforcement layers including a plurality of fiber strands, the plurality of said reinforcement layers being positioned by means of at least one layered spacer interposed between two adjacent reinforcement layers; and then injecting at least one unhardened polymer into the mold cavity to thereby surround said reinforcement layers with said polymer in the mold cavity; and then hardening the polymer to form said composite cover in said mold cavity, wherein at least one reinforcement layer includes a plurality of fiber portions connected to one another to define a single continuous fiber strand, said continuous fiber strand being positioned in the mold cavity in generally straight and parallel rows such that the continuous fiber strand is surrounded by the hardened polymer.
