Method of Making Reinforced Composite Articles with Reduced Fiber Content in Local Areas and Articles Made by the Method

摘要

A composite part including a resin matrix and fibers reinforcing the resin matrix in a first portion of the matrix. A second portion of the resin matrix is substantially devoid of fibers. The fibers may be in the form of a woven mat that defines an opening. Alternatively, the fibers may be loose fibers that are deposited in a mold that includes predetermined areas that are shielded from the deposit of the loose fibers. A method of making the composite part is disclosed in which a woven mat having an opening is filled with resin. Another method is also disclosed in which loose fibers are shielded from being deposited in a portion of the mold that is subsequently filled with resin.

1. A method of making a fiber reinforced composite part comprising:
providing a fiber mat defining an opening; inserting the fiber mat into a mold with the opening in a predetermined location in the mold; supplying a liquid resin to the mold that envelopes the fiber mat; and hardening the resin in the mold, wherein the resin fills the opening to provide a fastener receptacle area on the fiber reinforced composite part at the predetermined location.
