摘要
在流变、形貌和力学分析的基础上,采用将一系列经典模型经适当处理后与实验值相结合的方法,研究了热致液晶高分子分散相的原位成纤行为,并以几个物理参数表证分散相的成纤过程;推导了微纤模量与宏观模量的关系,定量计算出微纤的模量及其层分布研究结果表明,理论计算与实测值吻合良好.
Based on rheological,morphological andmicro-mechanical examinations, the formation behavior of a thermotropic liquid crystalline polymer as a dispersed phase in a thermoplastic matrix have been studied by using some theoretical models, which have to be only experimentally determined. The fibrillation conditions have been characterized by material and rheological constants such as We-number, viscosity ratio and critical burst time. Then, a relation between the fiber modulus, note the fibers still disperse in a matrix,and the composite modulus has been set up, so the fiber modulus can be quantitatively estimated. For both the fibrillation and the reinforcement, the results show a satisfactory agreement between the theoretical calculations and the experimental determinations. A preliminary idea for the TP / TLCP composite design has been therefore proposed.
