CFRT sheets (continuous fiber reinforced thermoplastic composite sheets), which is a multi- layer laminated sheets with thermoplastic unidirectional tapes laid at different angles (0°/90°, 45°/45°).This lamination method can compensates for the tensile strength of a single layer of unidirectional tape in the other direction.Continuous fibers give them strong mechanical properties and replace metal materials in many fields. This new type of glass fiber reinforced sheet can also replace traditional thermosetting FRP sheets. Because of its wide range of uses, stable performance, and high cost performance, CFRT sheets have become the first choice for many industries pursuing lightweight.
