摘　　要：运用DSC手段研究了UHMWPP/UHMWPE合金纤维的非等温结晶行为。采用Avrami方程和Avrami-Ozawa方程的结合(莫氏法)分析了其结晶能力和结晶活化能。分析F(T)及ΔE数据可知,UHMWPE作为成核剂加入有效地降低了结晶活化能,使得UHMWPP的结晶更容易。The kinetics of non isothermal crystallization of UHMWPP（ultra high molecular weight polypropylene）/UHMWPE （ultra-high molecular weight polyethylene） composite fiber was studied by means of differential scanning calorimetry （DSC）. Avrami equation and a combination of Avrami Ozawa （Mo methods） were used to analyze the crystallizability and the crystallization activation ener gies. The values of F（T） and AE showed that the crystallization activation energies decreased with the contents of UHMWPE. UHMWPE act as nucleating agent to speed the crystallization of the UHMWPP/UHMWPE composite fiber.
