Polymer fiber composite

A composite, comprising:

• a core layer comprising a thermoplastic polymer and having a first side and a second side opposite to the first side, wherein the core layer does not include reinforcing fibers;
• a first set of two layers disposed over at least a portion of the core layer respectively on the first side and the second side, each layer of the first set comprising carbon fibers aligned in a first direction in a plane;
• a second set of two layers disposed over at least a portion of the first set of two layers respectively on the first side and the second side, each layer of the second set comprising carbon fibers aligned in a second direction perpendicular to the first direction in the plane;
• and
• a third set of two layers disposed between the layers of the first set and the second set, respectively, on the first side and the second side, each layer of the third set comprising carbon fibers aligned in the first direction,
• wherein the composite in the plane has a length and a width, wherein the length is larger than the width and the length is parallel to the second direction, wherein the first direction is parallel to the width of the composite, wherein the composite has a thickness of less than or equal to 2.5 millimeters and has a flexural modulus of greater than or equal to 40 GPa.
