【摘要】：连续纤维增强热塑性树脂复合材料(FRTPRC)由于轻质、高强以及可回收再利用的特点,受到广泛的关注,其成型技术也不断更新。采用热塑性树脂传递成型(T-TRM)工艺,制备了纯尼龙6(APA6)板与连续玻纤增强尼龙6热塑性复合板(GF/PA6)。通过研究和分析模具温度、保温时间等工艺参数对APA6板的转化率、结晶度、黏均摩尔质量的影响,并且研究了不同纤维含量对GF/PA6复合材料力学性能的影响,同时采用傅里叶红外光谱测试与SEM电镜分析了GF/PA6复合材料的断裂形貌。结果表明,模具温度为170℃、保温时间为30 min时,尼龙6的结晶度和黏均摩尔质量达到最好,纤维含量增加,GF/PA6板的弯曲、拉伸强度增加;微观分析表明,玻纤与PA6树脂基体有较好的结合性,结合机理为浸润吸附原理。
[Abstract]:Continuous fiber reinforced thermoplastic resin composite (FRTPRC) has attracted wide attention due to its characteristics of light weight, high strength and recyclability. The molding technology is also continuously updated. The thermoplastic resin transfer molding (TTRM) process is adopted. The pure nylon 6 / APA6) board and the continuous glass fiber reinforced nylon 6 thermoplastic composite board were prepared. The die temperature was studied and analyzed. The effects of holding time on the conversion, crystallinity and average mole mass of APA6 were studied. The effects of different fiber content on the mechanical properties of GF/PA6 composites were also studied. At the same time, the fracture morphology of GF/PA6 composites was analyzed by Fourier transform infrared spectroscopy (FTIR) and SEM electron microscope. The results showed that the mold temperature was 170 鈩，
