【摘要】 利用扫描电子显微镜对玻璃纤维增强尼龙1010、碳纤维增强尼龙1010、三元乙丙橡胶增韧尼龙6等几种复合材料断裂行为的观察,以及对导致材料破坏因素的讨论表明,增韧增强介质与基体树脂的粘结及分布将直接影响材料的力学性能,而力学性能的变化又将明显地反映在微观断裂形态上。更多还原

【Abstract】 The observation on the fracture morphology for the composites such as,glass fiber reinforced nylon 1010,carbon fiber reinforced nylon 1010,and EPDM-rubber toughened nylon 6, and the discussion on the factors influencing fracture of the materials show that the adhesion and distribution of the toughening and reinforcing agents with resin matrix directly affect on the mechanical properties of the material,and the changes in the mechanical properties are obviously reflected in fracture morphology.更多还原
