简要地叙述了在纤维树脂复合材料中的孔隙和测量孔隙含量的各种方法,以及孔隙对复合材料力学性能的影响。 结论:不论树脂、纤维类型或纤维表面的处理如何,复合材料中孔隙在4％以内每含有1％的孔隙,其层间剪切强度减少约7％,其他机械性能虽然程度不同,也受孔隙的影响。 A brief account of the porosity in fiber-resin composites and various methods for measuring the pore content, as well as the effect of porosity on the mechanical properties of the composites, CONCLUSION: Regardless of the resin, fiber type or fiber surface treatment, the porosity of the composite is within 4% for every 1% of the pores and the interlaminar shear strength is reduced by about 7%. Other mechanical properties, although of different degrees, are also affected by the porosity Impact.
