Laser Heating Technology for Thermoplastic Carbon Fiber Composites

Continuous fiber-reinforced thermoplastic composite manufacturing processes, represented by the automated placement and forming technology of thermoplastic composites, have become a research hotspot at home and abroad in recent years. This is attributed to their advantages including a simple forming process, high efficiency, low cost, and recyclability of materials.

During the automated placement process, thermoplastic prepregs pass sequentially through the heating zone, compression zone and cooling zone. In the heating zone, the resin matrix of the prepreg melts under the action of a heat source, endowing the prepreg with flowability and viscoelasticity that meet the requirements of subsequent placement. The prepreg then enters the compression zone. At the nip point, the upper and lower layers of prepreg with molten resin flow and bond together under normal compression force. Afterwards, the laid plies move into the cooling zone, where the resin matrix undergoes cooling crystallization and achieves complete consolidation.
