摘 要: 对称复合材料层板面内和厚度方向泊松比的计算公式已经推出,本文设计制作了两组面内泊松比不同的复合材料层板,比较了它们的断裂韧性,发现泊松比小的一组材料比泊松比大的常规平衡复合材料的断裂韧性高。最后,通过观察断口形貌分析了原因。 The formulas for calculating poisson’s ratio in-plane and the through-the thickness of composites symmetric laminate have been derived. This paper designs and makes two different composites laminates with different Poison’s. After comparing the fracture toughness, it is found that the laminate with smaller Poison’ a ratio has higher fracture toughness than the balanced composites laminate with the bigger Poison’s ratio. The reason is analyzed by ob-serving the morphology of the fracture.
