摘要整理
近年来，树脂制造商开发了固化时间更短的热固性树脂，这有助于缩短工艺周期时间，为采用成本效益高的压缩树脂传递模塑（CRTM）工艺生产高性能复合材料零件铺平了道路。然而，高反应性树脂在生产高质量零件时面临重大挑战。目前，许多研究人员正在开展CRTM工艺模拟研究，但在热传递、固化动力学、树脂流动和压实（热-化学-力学）耦合方面仍存在较大差距，特别是对于三维结构。本工作的主要目标是对平面三维零件进行热-化学-力学耦合CRTM工艺模拟。研究包括树脂和纤维材料模型的开发，将所建立的材料模型用于工艺模拟，并通过中断树脂流动CRTM实验对模拟结果进行验证。该研究在多物理场耦合模拟方面取得进展，为优化CRTM工艺参数、提高复合材料零件质量提供了理论基础。
