碳纤维/MC尼龙6原位复合材料的非等温结晶动力学
Non-Isothermal Crystallization Kinetics of CF/MC Nylon 6 In-Situ Composites
【摘要】 采用差示扫描量热(DSC)法,研究表面接枝聚己内酰胺链段的碳纤维(CF)/单体浇铸(MC)尼龙6原位复合材料,以及其在不同冷却速率下的结晶动力学特性;用Jeziorny法和Liu法对它们的非等温结晶动力学进行处理.结果表明,碳纤维对基体尼龙6的结晶有一定的促进作用,提高了结晶温度和结晶速率.表面接枝聚己内酰胺链段的碳纤维/MC尼龙6原位复合材料,比未接枝的碳纤维/MC尼龙6原位复合材料具有更高的结晶温度、结晶速率和更大的结晶度.
【Abstract】 Non-isothermal crystallizations of the polycaprolactam chain segment grafted carbon fibre(CF)/monomer casting(MC) nylon 6 in-situ composites were investigated at different cooling rates by means of differential scanning calorimetry(DSC).Their non-isothermal crystallization kinetics were described by Jeziorny method and Liu method.Results showed that the carbon fiber can promote the crystallization of MC nylon 6 matrix and enhance crystallization temperatures and crystallization rates.The crystallization temperature,crystallization rate and crystallization degree of the polycaprolactam chain segment grafted CF/MC nylon 6 in-situ composites are higher than those of un-grafted CF/MC nylon 6.
