Background
Thermoplastic polymer composite particles are typically made by co-extruding the polymer and reinforcing fibers using twin screws. The reinforcing fiber used in the method is usually inorganic fiber such as glass fiber, carbon fiber, basalt fiber and the like, and the density of the reinforcing fiber is far higher than that of the polymer, so that the density of the composite material particle is also higher. The weight reduction of materials is a goal of the current market, and thus the preparation of polymer composites using polymer fibers with a density close to that of the polymer matrix material as a reinforcing material is gaining attention. The reinforcing fibers of the in-situ fiber-forming composite are not prepared by direct addition, but the dispersed phase is oriented by shearing or stretching during processing and is formed in situ.
