A fiber composite material comprises a polymer matrix, carbon fibers, and non-carbon fibers, wherein the non-carbon fibers have a strain to failure value greater than the strain to failure value of the carbon fibers. Also discussed is a preform (52) comprising the fiber composite material combined in a three dimensionally woven structure. Also discussed is a fan blade (62) for a jet engine (20).
