摘　　要：根据哑铃状增强纤维的仿生分析，建立了弱结合界面模型和理想弹塑性基体增强复合材料强度唯象理论．证明哑铃状纤维增强效果优于平直纤维．理论预测与实验结果吻合较好．According to the biomimetic research for fibres with enlarged ends,the model of imperfect-bonding interface and the strength theory of composite materials with perfect elastic-plastic matrix have been put forward.It has also been proved that the tensile strength of composite materials reinforced by fibres with enlarged-ends is higher than that by plain fibres.The theoretical and experimental results are in fairly good agreement.
