Abstract
A composite part consisting of a metallic matrix and reinforcing fibers is fabricated by the simultaneous winding of the fiber and plasma spraying of the matrix onto a rotating mandrel, wherein an axi-symmetric part is produced with multiple layers of the fibers aligned in the circumferential direction. Single or multiple fiber strands are wound onto a mandrel and simultaneously sprayed with the heated powder matrix material using a thermal spray process. Rotation and translation of the mandrel produces an axi-symmetric composite part. The content of the fiber material in the plasma sprayed matrix is typically up to 40% by volume. The light-weight composite part is produced in a single processing step. The part may be used either directly, or as an insert in other components with or without further densification.
