Polyether ether ketone (PEEK) and carbon fiber rod have excellent properties, and there is a good interface between PEEK and carbon fiber rod. Carbon fiber rod can also act as heterogeneous nucleating agent to promote the crystallization of PEEK in composites. The high performance composites prepared by combining PEEK and carbon fiber rod will have more excellent properties.
In the 1980s, ICI first prepared unidirectional carbon fiber rod reinforced polyether ether ketone preprepreg by pultrusion and melt impregnation, and then developed a series of prepregs named APC, among which APC-1 is a commercial continuous carbon fiber rod reinforced polyether ether ketone composite prepreg.
APC-2 has better comprehensive performance than APC-1. It is a well-known brand at present. The commercial APC-2 consists of a series of one-way preprepreg tapes with a thickness of 125?M. The volume content of carbon fiber rods is about 60%.
APC-2 has excellent mechanical properties, its tensile strength is usually greater than 2000 MPa, its tensile modulus is greater than 135 GPa, its bending strength is usually greater than 1700 MPa, and its bending modulus is greater than 120 GPa. In addition, APC-2 has a series of excellent properties, including good impact resistance, excellent thermal stability at high temperature.
Extremely resistant to moisture and heat aging, chemical agents, etc. Because of the excellent properties of APC series preprepregs, since ICI put them on the market, they have rapidly become practical advanced thermoplastic composites in aerospace field, especially in military aircraft.
For example, polyether ether ketone carbon fiber rod composites have been used in the manufacture of helicopter rotor and missile shell in the United States, and the stealth helicopter LHX in the United States has adopted such composites. In addition, the F-117A fully automatic tail, the C-130 fuselage abdominal panel, the French gust fan body skin and so on all use this composite material.
Although APC series has a series of outstanding properties, for commercial reasons, ICI company keeps the forming technology of APC series under strict confidentiality.
Due to the high melting viscosity of PEEK and its insolubility in almost any solvent, the preparation of continuous carbon fiber rod reinforced PEEK composites has always been a technical problem to be solved.
In recent years, with the increasing demand for continuous carbon fiber rod reinforced polyether ether ketone composites, a series of new forming technologies have emerged, which effectively overcome the difficulty of impregnation of polyether ether ketone.
