Research progress and automotive application prospects of 3D printed fiber reinforced composites
Aiming at the technical bottlenecks faced by the conventional fabrication process of fiber reinforced polymer composites,the domestic and international research progress of 3D printing technology in the field of the composites were briefly described.The development trends of the 3D printed fiber reinforced composites were systematically summarized,spanning from short fiber/thermoplastics,short fiber/thermosets,to continuous fiber/thermoplastics and continuous fiber/thermosets.By review-ing and comparing different process schemes at home and abroad,the core potentials of the composite 3D printing in terms of advanced material substitution,reduction of process complexity,enhancement of production flexibility,and cost savings,were high-lighted.The broad prospects of this technology among the automotive manufacturing chains were revealed.Further design and appli-cation,and innovative progressions of the composite 3D printing in the future were pointed out.
