Abstract
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.
