Composite sheet: A composite sheet material made from unidirectional tapes. It is a laminated material formed by the molten impregnation and curing of a resin matrix (thermoplastic) with continuously arranged glass fibers or carbon fibers in a unidirectional arrangement as the reinforcement. Its core characteristics stem from the high anisotropy brought about by the directional arrangement of the fibers.

The axial tensile strength is much higher than that of ordinary metals.

The tensile elastic modulus is generally 75 - 100 GPa, achieving ultra-low deformation.

It has better fatigue resistance and is suitable for long-term load-bearing structures such as wind turbine blades and bridge reinforcement.

It has many characteristics such as corrosion resistance, low hygroscopicity, flexible lay-up design, and efficient molding.
