摘　　要：以预浸料为原料的先进拉挤(Advanced Pultrusion)采用预浸料预变形折弯定型-热固化成形,是制造高性能低成本复合材料型材的一种先进自动化工艺。基于预浸料变形特征分析,以C型梁为对象建立了预成形分析的理论模型,通过实验验证了模型和方法的正确性;为进一步开展其他复合材料型材的先进拉挤研究与应用奠定了基础。Advanced pultrusion is an automatic processing for manufacturing high performance and low cost composites section components with prepreg by pre-forming, hot pressing and curing steps. Based on deformation analysis, a theory model for C-type beam is set up. An experiment is conducted to verify the model and analysis method which will build the foundations for the advanced pultrusion with other section components.
