Abstract
A fiber reinforced composite structure and method for fabricating the composite, are described wherein four sets of mechanically flexible fibers are interwoven in a three-dimensional woven structure wherein each fiber is woven through the structure generally along one of the four directions defined generally parallel to a body diagonal of a cube, and wherein the woven structure is impregnated with polymeric, metallic or ceramic matrix material to form a composite material which is braced against deformation by shear applied in any orientation.
Claims15
A fiber reinforced composite structure comprising:
- (a) a three-dimensional woven structure of a multiplicity of four sets of fibers interwoven in said structure wherein each fiber set is woven through said woven structure generally along one of the four directions defined generally parallel to a body diagonal of a cube;
- and
- (b) a matrix material disposed within said woven structure.
A method for fabricating a fiber reinforced composite, comprising the steps of:
- (a) providing a source of four fibers for weaving into a woven structure;
- (b) constructing a three-dimensional woven structure of a multiplicity of four sets of said fibers interwoven in said structure wherein each fiber set is woven through said woven structure generally along one of the four directions defined generally parallel to a body diagonal of a cube;
- and
- (b) impregnating said woven structure with a matrix material.
