摘 要: 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 ,发现泊松比为负的一组材料比常规平衡复合材料的断裂韧性高。最后 。 The formulas for calculating plane Poisson's ratio and thick Poisson's ratio of the composite laminates have been given in some literatures.In this paper,the critical stress intensity factor of composite with different plane Poisson ratio is compared and the critical stress intensity factor of composite with negative Poisson ratio is higher than with the balanced laminates.The cause is analyzed by observing the morphology of the fracture.
