Abstract

Abstract: By unidirectional tensile test , the ultimate longitudinal tensile perfonnance of interply hybrid GFRP/CFRP was investigated, which involved 5 different hybrid ratios of GFRP and CFRP , 4 layout patterns of GFRP and CFRP , and the influence of 3 different structural adhesives on the ultimate longitudinal tensile performance of interply hybrid GFRP/CFRP. The improvement mechanism of interply hybrid of GFRP/CFRP was also analyzed. The test results show that: the interply hybrid GFRP/CFRP sheet has significantly changed the linear elastic characteristics of single type of FRP up to failure and possesses with obvious yield plateau; when the volume fraction of CFRP in the interply hybrid GFRP/CFRP composite ran ges from 0.29-0.45 , the interply hybrid GFRP/CFRP composite is characterized with good deformation and strength propert1es.

Key words: interplay hybrid composite, hybrid ratio, tensile performance

摘要： 采用单向拉伸试验，研究了5种GFRP/CFRP混杂比，4种层间泪杂铺设方式，及3种结构胶对GFRP/CFRP层间由杂纤维纵向极限拉伸性能的影响，分析了GFRP/CFRP层间混杂复合材料拉伸性能改善机理。试验结果表明: GFRP/CFRP层间混杂纤维复合材料显著改善了单一复合材料拉伸弹脆性特性，具有明显的屈服台阶;当CFRP体积份数为0.29-O.45,GFRP/CFRP层间混杂材料具有良好的变形性能和强度特性。
