摘　　要：本文分别用热塑性树脂聚砜及加入反应性增塑剂双〔4(4-乙炔基苯氧基)苯基〕砜以改进聚砜的热性能及加工性能的混杂树脂作基体,研究了碳纤维、玻璃纤维和两种纤维混杂增强的夹芯层板的弯曲和冲击力学性能。除比较了这两种基体复合材料的常温力学性能外,还详细讨论混杂复合材料的混杂效应。应用这些效应,材料的价格及综合性能将得到合理的选择和平衡。In this paper, the bending and impact behaviors of the composites of carbon fiber, glass fiber and C/G hybrid fiber reinforced thermoplastics have been studied. Two kinds of matrices used in the composites are respec tively polysulfone (PSF) and its blend. In the latter a little of bis (4-(4-ethynylphenoxy) phenyl) sulfone (ESF) is added in order to improve the processing and thermostable properties of PSF. The experimental curves of bending and impact properties of composites against component ratio, E_(bH)-V_(cf)/V_f, O_(bH)-V_(cf)/V_F and a_n-V_(cf)/V_f, have been obtained. They are in agreement with the theoretical calculation developed from theory of sandwich laminates. Comparing the testing results of the C/G hybrid composites of PSF with the C/G hybrid composites of the new blend, PSF/ESF, it was observed that the difference in the mechanical properties between the two series of composites is not large due to the amount of ESF in the blend is rather small (only 10％). But the brittlness of all hybrid composites is raised obviously. Based on the testing information, the hybrid effect of the composite with hybrid fibers has been disscussed in datail and it is suggested that hybrid technology should be used mainly for gaining the best comprehensive peculiarities (the structural and/or the functional) and decreasing manufaeturing expenses.
