基于界面粘结区模型和细观力学分析，研究了纤维增强聚合物基复合材料的界面粘结强度模型。假定聚合物基体的本构关系为线性粘弹性本构关系，将纤维视为刚体。根据能量守恒原理和EShelby׳S等效夹杂方法，对纤维与基体的界面脱粘进行了分析，提出了一种新的界面结合强度模型。结果表明，界面粘结强度对纤维半径R有奇异性，但不存在−~(1/2)奇异性。数值讨论了基质的泊松-׳-S比、脱粘角、驰豫时间和纤维半径等因素的影响。结果表明，由于粘聚力的存在，其强度比不考虑粘聚力时的强度要大。
Interfacial adhesive strength model for fiber-reinforced polymeric composites is investigated based on the cohesive-zone model of interface and mesomechanics analysis. The constitutive relation for the polymer matrix is assumed to be a linear viscoelastic one, and the fiber is considered as a rigid body. According to the principle of energy conservation and Eshelby׳s equivalent inclusion method, The interfacial debonding between the fiber and matrix is analyzed, and a new interfacial adhesive strength model is suggested. It is found that the interfacial adhesive strength has singularity with respect to the radius,R, of the fiber, but it is notR~(−1/2) singularity. The effects of the Poisson׳s ratio of matrix, debonding angle, relaxation time of matrix, and the radius of the fiber are all numerically discussed. It is found that owing to exist of cohesive force, the strength is greater than that without considering such a cohesive force.
