Composite materials and structures

A fiber reinforced composite material having impact resistance, the composite material comprising:

• a first TPW fabric layer, the first TPW fabric layer comprising a plurality of weft tows and a plurality of warp tows, wherein at least one of the plurality of tows defines an orientation direction, and
• a second TPW fabric layer, the second TPW fabric layer comprising a plurality of weft tows and a plurality of warp tows, wherein at least one of the plurality of tows defines an orientation direction, wherein,
• the first and second TPW fabrics layers are arranged in a helicoidal relationship and wherein an included angle between the orientation direction of the tows of the first TPW fabric layer and the orientation direction of the tows of the second TPW fabric layer is more than 0° and less than about 30° to provide impact resistance for the reinforced composite material.

A fiber reinforced composite material having impact resistance, the composite material comprising:

• a first QUDW fabric layer, the first QUDW fabric layer comprising a plurality of weft tows and a plurality of warp tows, wherein the plurality of warp tows defines an orientation direction, and
• a second QUDW fabric layer, the second QUDW fabric layer comprising a plurality of weft tows and a plurality of warp tows, wherein the plurality of warp tows defines an orientation direction, wherein
• the first and second QUDW fabrics layers are arranged in a helicoidal relationship and wherein an included angle between the orientation direction of the warp tows of the first QUDW fabric layer and the orientation direction of the warp tows of the second QUDW fabric layer is more than 0° and less than about 30° to provide impact resistance for the reinforced composite material.
