| 摘 要： | 采用纳米碳酸钙(CaCO_3)浸渍改性工艺对竹浆纤维(BPF)进行改性,并采用真空辅助树脂浸注(VARI)技术制备纳米浸渍改性竹浆纤维(IMBPF)/环氧树脂复合材料.利用热失重分析(TGA)方法研究了原材料和复合材料在氮气气氛下的热降解行为,采用Flynn-Wall-Ozawa(FWO)和Vyazovkin and Weight(VW)方法量化了复合材料的表观活化能.结果表明:IMBPF/环氧树脂复合材料出现300~400,400~450,600~700℃3个失重区,分别对应BPF、环氧树脂和纳米CaCO_3的热降解;采用FWO法和VW法测定的IMBPF/环氧树脂复合材料的表观活化能均高于对照样(未改性的BRF),且FWO法估算数值高于VW法;纳米CaCO_3对复合材料的热降解特性具有调控作用;FWO法和VW法处理的结果总体相差不大,但前者优于后者.
