摘　　要：纤维增强在热塑性复合材料中使用广泛,但易使材料黏度增大,加工机械磨耗严重。本文综述了近年利用原位复合技术增强的研究成果,主要从共混体中连续相和分散相的相容性、黏度比、界面张力、加工成型参数(剪切速率、毛细管或口模的形状和大小、加工温度)这几个成纤影响因素作了重点阐述。此方法可有效降低材料加工黏度、提高材料力学性能,对制备高性能复合材料具有重要意义。fiber reinforcing is widely used in thermoplastic composite materials, however, which easily makes material viscosity increased, severely worn off the processing machinery and equipment. A recent use of the research achievement of reinforcing by on site composite technology was reviewed in this article, with a description made mainly with emphasis on the several fiber formation effecting factors, such as compatibility of the continuous phase and dispersion phase in the blend, viscosity ratio, interfacial tension, processing and forming parameters （shear rate, capillary or die shape and dimension and processing temperature） etc. This process can effectively reduce the material processing viscosity and improve the material mechanics properties, which is of great importance to the manufacture of high performance composite materials.
