Abstract In the present work, the effect of stacking sequence on tensile and flexural properties of carbon-glass/epoxy hybrid composite laminates are reported. The composite laminates fabricated using resin infusion technique were subjected to tensile and flexural test as per ASTM D-3039 and ASTM D-790 standards respectively. The fracture surfaces after each test were studied using scanning electron microscope to arrive at possible failure mechanisms. Out of the two laminates tested, the one with carbon fabric positioned at exterior regions showed highest tensile and flexural strength of 380.35 MPa and 615.48 MPa respectively. Both the tensile and flexural failure analysis showed fiber breaking and fiber pull out as main causes for failure. Composite laminate with glass fabric at the exterior showed interface decohesion as major failure mechanism. This study showed importance of stacking carbon fabric at right position to obtain better tensile and flexural properties which is very important from composite design and cost point of view.

研究不同碳纤维和玻璃纤维织物堆叠顺序对环氧杂化复合材料层压板力学性能的影响

摘要 在目前的工作中，报告了堆叠顺序对碳-玻璃/环氧树脂混合复合材料层压板的拉伸和弯曲性能的影响。使用树脂灌注技术制造的复合层压板分别按照 ASTM D-3039 和 ASTM D-790 标准进行拉伸和弯曲试验。使用扫描电子显微镜研究每次测试后的断裂表面，以得出可能的失效机制。在测试的两种层压板中，碳纤维织物位于外部区域的层压板分别显示出最高的拉伸强度和弯曲强度，分别为 380.35 MPa 和 615.48 MPa。拉伸和弯曲失效分析均表明纤维断裂和纤维拉出是失效的主要原因。外部带有玻璃织物的复合层压板显示界面脱聚是主要的失效机制。
