In recent years, fiber reinforced thermoplastic composites based on thermoplastic resins have developed rapidly, leading to a worldwide upsurge in the research and development of such high-performance composites. Thermoplastic composite materials refer to composite materials made from thermoplastic polymers such as polyethylene (PE), polyamide (PA), polyphenylene sulfide (PPS), polyetherimide (PEI), polyetherketone ketone (PEKK), and polyetherketone (PEEK), with various continuous/discontinuous fibers (such as carbon fibers, glass fibers, aramid fibers, etc.) as reinforcing materials.

Thermoplastic resin based composites mainly include long fiber reinforced granular material (LFT) continuous fiber reinforced prepreg MT and glass fiber reinforced thermoplastic composites (CMT). According to different usage requirements, the resin matrix includes thermoplastic engineering plastics such as PPE. PAPRT, PELPCPES, PEEKPI, PA, and other fiber types, including all possible fiber types such as glass dried vinylon fiber and boron vinylon. With the maturation of thermoplastic resin based composite technology and the development of recyclability, this variety of composite materials has developed rapidly. In developed countries in Europe and the United States, thermal bonding materials have accounted for more than 30% of the total amount of tree based composite materials.

Thermoplastic matrix

Thermoplastic matrix is a thermoplastic material with good mechanical properties and heat resistance, which can be used to manufacture various industrial products. Thermoplastic substrates are characterized by high strength, high heat resistance, and good corrosion resistance.

Currently, thermoplastic resins used in the aviation field are mainly high-temperature resistant and high-performance resin matrices, including PEEK, PPS, and PEI. Due to its lower processing temperature and cost, amorphous PEI is more widely used in aircraft structures than semi crystalline PPS and high molding temperature PEEK.
