ABSTRACT:
An apparatus and method for the production of composite material parts by aligning reinforcing fibers through application of electric fields. The fibers are in the form of rods preimpregnated with a matrix material or coated with a sizing, and aligned within a dielectric alignment fluid. By providing appropriate electrodes, an electric field is created which mimics the stress lines exhibited by the final composite part when under stress. The reinforcing fibers align to the electric field, thereby aligning to the stress lines.
