Abstract
In order to improve the interlaminar shear property of the composites manufactured by the additive of aramid fiber (AF) reinforced with polylactic acid (PLA), the preparation process of AF reinforced thermoplastic resin composite micro-wires has been optimized, which could promote impregnated and toughness. The influence of different water bath temperatures on the interlaminar shear properties of the composites was studied. And the results showed that the largest interlaminar shear strength (ILSS) of AF/PLA composite material was 12.0 MPa, which had confirmed in the water bath temperature of 30°C. As the bath temperature increased, the interlaminar shear performance decreased, and the ILSS of composite micro-wires in 70°C water bath was 74.67% of that in 30°C water bath. The composite fiber with high impregnation degree and good toughness has laid a foundation for further research on additive manufacturing of AF/PLA composite.
