应用ANSYS有限元商用软件,建立单向玻璃纤维增强树脂基体复合材料轴对称平面Whitney和Riley分析模型,利用非线性有限元分析方法,研究该类复合材料纤维长径比变化对材料整体力学行为的影响,同时研究该类复合材料中纤维与基体界面结合强度分布形式对材料破坏方式的影响.研究表明:纤维在基体中的埋深长度与基体对纤维包裹厚度应保持在一个最佳范围,高过一定值后增强作用几乎不再增加,过低又不能保证复合材料足够力学性能;随着纤维与基体上端界面结合强度增加,纤维界面上端正应力绝对值出现最大值,并且纤维界面上下端正应力转化为压应力,因此材料的断裂位置为上端加持部位附近,下端加持部位附近没有出现界面脱粘现象;随着纤维与基体下端界面结合强度的增加,纤维界面下端正应力绝对值出现最大值,并且纤维界面上下端正应力转化为分离力,因此材料断裂位置为材料下端加持部位附近,上端加持部位附近出现纤维与基体脱粘现象.
