Continuous Carbon Fiber Reinforced PPS Composite Pipe

Advanced resin-based composites are respected in many industrial fields for their light weight, high strength, and fatigue resistance. However, the high production cost hinders the development of advanced resin-based composite materials 4). In the 1980s, a large number of experimental studies were conducted in Western countries mainly in the United States, and gradually developed technologies such as winding molding, pultrusion molding, laying molding, and silk molding, in order to reduce the cost of composite materials and improve the level of composite materials To lay the foundation for a large number of applications in industry.

Through heat treatment, the IISS of continuous carbon fiber reinforced PPS composite pipe has been improved. During the molding process, the thermal expansion coefficients of both the fiber and the matrix are different. During the molding, a large residual stress will be generated at the interface between the fiber and the resin. It can also improve the interfacial bonding strength between fiber and resin matrix; therefore, after treatment, ILSS is imp

Under the harsh conditions of boiling water immersion, the composite pipe reaches the maximum water absorption rate at about 1 hour, at which time the water absorption rate is 0.66% .Because the water absorption rate of PPS itself is also relatively low, plus the pressure during the forming process, The interlayer adhesion is strong, and water molecules are neither easily absorbed nor penetrate into human materials.roved.
