Method for fabricating composite fasteners

摘要

Composite fasteners have a high fraction of discontinuous, randomly oriented reinforcing fibers. A charge of thermoplastic fiber flakes are heated to melting temperature within a reservoir, flowed into multiple mold cavities and compression molded. The molded fasteners have high strength, exhibit quasi-isotropic properties and may be produced in high volume.

主权项

1. A method of producing a composite fastener, comprising:
introducing thermoplastic resin infused fiber flakes into a reservoir; heating the infused fiber flakes in the reservoir to the melting temperature of the thermoplastic resin, resulting in a mixture of melted thermoplastic resin and fiber flakes; and, flowing the mixture of the melted thermoplastic resin and fiber flakes into a mold having the shape of the fastener.
