Abstract

The present invention contemplates a high strength magnetic composite material system (35) comprising a plurality of high strength fibers (30) coupled together by a soft magnetic alloy (31). In one embodiment an internally reinforced structure is formed of the composite material system (35) and has strengths greater than the monolithic magnetic alloy. The structure having been consolidated through a combined pressure and thermal cycle.
