A 3D thermoplastic pultrusion system, comprising:
- one or more sets of 3D thermoplastic forming machines;
- a CNC control system controlling the one or more sets of 3D thermoplastic forming machines to form a heated prepreg thermoplastic composite material into a 3D thermoplastic composite pultrusion.
A method of creating a 3D thermoplastic composite pultrusion with a 3D thermoplastic pultrusion system including one or more sets of 3D thermoplastic forming machines, comprising:
- providing composite material including one or more thermoplastic composite tapes;
- heating the composite material including one or more thermoplastic composite tapes with a heating mechanism;
- controlling the one or more sets of 3D thermoplastic forming machines with a CNC control system to form the heated composite material including one or more thermoplastic composite tapes into a 3D thermoplastic composite pultrusion.
An airfoil manufactured by a process, the process comprising:
- providing composite material including one or more thermoplastic composite tapes;
- heating the composite material including one or more thermoplastic composite tapes with a heating mechanism;
- controlling one or more sets of 3D thermoplastic forming machines with a CNC control system to form the heated composite material including one or more thermoplastic composite tapes into the airfoil.
