Title: Composite components and methods of manufacturing composite components using magnetic forces at fiber preform seams

Abstract

A method of manufacturing a composite component according to various aspects of the present disclosure includes disposing a fiber preform in a mold. The fiber preform includes a first portion having a first edge and a second portion having a second edge. The first edge and the second edge cooperate to at least partially define a gap. One of the first portion or the second portion includes a first ferromagnetic material and the other of the first portion or the second portion includes a first magnetic or magnetizable component. The method further includes closing the gap by generating a magnetic field from the first magnetic or magnetizable component. The method further includes injecting a polymer precursor into the mold. The method further includes forming the composite component by solidifying the polymer precursor to form a polymer. The composite component includes the fiber preform and the polymer.
