Method and compositions for embedding electronics in fiber-composite parts fabricated via compression molding

A fiber-composite part having one or more electronic components that are located in arbitrary regions of the internal volume of the part are fabricated using a preform charge. The preform charge has a structure that corresponds to that of the mold cavity in which the part is being formed. By incorporating the electronic components in the preform charge, such components are then precisely located, spatially oriented, and constrained, and such location and orientation is maintained during molding to produce a part with the electronic components in the desired locations and orientations within its internal volume.
