Abstract

Abstract Liquid composite molding (LCM) suffers from multiple factors that contribute to pronounced uncertainty of process characteristics. This results in compromised reproducibility which is associated to high scrap or the unpredictable behavior of approved parts. However, LCM is still attractive for Fiber-reinforced polymeric composites (FRPC) production due to its economic advantage (i.e. in relation to Autoclave), the capability of some of its variants to produce high performance parts and its potential for process optimization. This review analyzes each uncertainty with respect to its origins and its impact in part or process, based on a combination of past literature and original numerical results. The possible methods to counteract uncertainties are critically discussed, with an eye on both the scientific and feasibility (technical/economical) aspects. The overall aim is to provide to future LCM implementations a roadmap of the most critical challenges and solutions regarding the establishment of a reproducible process. Graphical abstract

液体复合成型再现在现实世界生产的纤维增强聚合物复合材料:挑战和解决方案的回顾

液体复合成型(LCM)受到多种因素的影响，导致工艺特性的明显不确定性。这导致重复性受损，这与高废品率或批准零件的不可预测行为有关。然而，由于其经济优势(即与高压釜相关)，LCM仍然对纤维增强聚合物复合材料(FRPC)生产具有吸引力，其一些变体生产高性能部件的能力以及工艺优化的潜力。本文基于过去文献和原始数值结果的结合，分析了每种不确定性的起源及其对部分或过程的影响。从科学和可行性(技术/经济)两个方面对抵消不确定性的可能方法进行了批判性讨论。总体目标是为未来的LCM实现提供关于建立可复制过程的最关键挑战和解决方案的路线图。图形抽象
