摘　　要：层间滑移是预浸料叠层预成型中重要成型机制之一,层间滑移机制的研究可以对起皱和撕裂等缺陷进行有效预测和控制,对提高复合材料的力学性能和使用寿命具有重要的理论意义。目前,层间滑移机制的研究主要通过层间滑移测试和层间滑移模型构建的方式进行,其中最常用的测试方法是通过自主搭建层间滑移装置进行不同预浸料铺层和工艺条件下的性能测试;在模型构建方面,根据层间滑移模型的构成特点,可将模型分为3类:早期混合模型、基于Stribeck理论的唯象模型和经验模型。本文首先对层间滑移装置进行分类综述,剖析了每种类型装置的优缺点,然后详细介绍了层间滑移性能的表征及模型的构建等研究成果,最后对树脂基复合材料成型中的层间滑移发展方向进行了展望。Inter-ply slipping is one of the important mechanisms in prepreg stacking preforming,and the research of inter-ply slipping mechanism can effectively predict and control the defects such as wrinkling and tearing,which is of great theoretical significance to improve the mechanical properties and service life of composites.At present,the research on inter-ply slipping mechanism mainly involves inter-ply slipping tests and the construction of interply slipping models.The most commonly used test method is to conduct inter-ply slipping test using the homemade measuring device under different prepreg layups and process conditions.In terms of model construction,according to the characteristics of the inter-ply slipping model,the model can be classified into three categories:Early mixed models,phenomenological models based on Stribeck theory and empirical models.In this paper,firstly,the classification of inter-ply slipping devices is reviewed,and the advantages and disadvantages of each type of device are dissected.And then the research results such as the characterization of inter-ply slipping performance and the construction of models are introduced in detail.Finally,the development direction of inter-ply slipping in the resinmatrix composite forming is prospected.
