Study on low-speed impact performance of CAF/PA12 composites forming specimens
There are some differences in the mechanical properties of the molded parts prepared by composite fila-ment with different fiber content.In order to improve the low-speed impact performance of continuous aramid fiber reinforced nylon 12(CAF/PA12)composite molded parts,the effects of impact energy and fiber content of com-posite filament on the low-speed impact performance of molded parts were investigated.The impact resistance of forming parts made of composite filament with low fiber content was investigated by single factor experiment under different impact energy.The low-speed impact properties of the composite forming parts prepared by four kinds of fiber content composite wires were analyzed.The experimental results show that the molded parts with 36.14％fi-ber content have better low-speed impact performance.
