One example provides a composite. The composites includes a core layer comprising a thermoplastic polymer and having a first and a second sides opposite to each other; a first set of two layers disposed over at least a portion of the core layer respectively on the first and the second sides, each layer of the first set including carbon fibers aligned in a first direction in a plane; and a second set of two layers disposed over at least a portion of the first set of two layers respectively on the first and the second sides, each layer of the second set including carbon fibers aligned in a second direction perpendicular to the first direction in the plane In the plane, the composite has a length and a width, the length larger than the width and parallel to the second direction.
