摘要： A liquid acrylic resin used in reactive thermoplastic pultrusion that produces a nanocomposite/fiber-reinforced hybrid composite structure with relatively high tensile strength and high flexural strength compared to thermoplastic fiber-reinforced composites made using resin transfer molding processes. The resin is made of 70-90% methyl methacrylate, 10-30% polymeric viscosity-promoting agent, a 0.1-10% nano clay, a nitro compound retarder and an internal lubricant. The pultrusion process is carried out in a pultrusion machine that uses a relatively high percentage of fibers. The fibers are submerged in a resin bath and delivered to a curing die. Before manufacturing the resin, the inhibitor for the monomer is removed using an Alumina column and replaced with the nitro retarder. The nano clay is added to promote the reaction rate. Any resin and pultruded wastes produced during the manufacturing process can be processed and reused. Also disclosed is a method for manufacturing a composite made of the liquid acrylic resin and pultrusion dies systems.
