摘要

在任何复合材料制造过程中,特别是在没有真空辅助的情况下,孔隙度的形成都是一个主要的挑战。将聚合物基体高度局部地注入干预制体中感兴趣的区域是制造具有高填料浓度的多基体纤维增强复合材料的途径,否则难以实现。与传统复合材料不同,这种多基体纤维增强复合材料系统将多种树脂以连续形式组合在一起,可以改善应力集中器的结构性能和多功能性能。由于该工艺缺乏真空辅助,孔隙率成为需要解决的主要问题。本文提出了一种流变动力学耦合的快速固结方法,用于优化局部矩阵贴片的质量。该程序包括制造试验和分析巩固模型,以确定最小的贴片空隙的最佳加工程序。该结果为设计多基复合材料的高效制造工艺提供了一步,而不需要复杂的真空袋布置。通过优化局部矩阵块的质量,可以提高多矩阵复合系统的整体性能。在不需要复杂的真空袋布置的情况下制造这些复合材料的能力也可以减少与制造多基体纤维增强复合材料相关的制造成本和时间。

MANUFACTURING MULTI-MATRIX COMPOSITES: OUT-OF-VACUUM BAG CONSOLIDATION
The formation of porosity is a major challenge in any composite manufacturing process particularly in the absence of vacuum assistance. Highly localised injection of polymer matrix into regions of interest in a dry preform is a route to manufacturing multi-matrix fibre-reinforced composites with high filler concentrations which are otherwise difficult to achieve. Such multi-matrix fibre-reinforced composite systems, which combine multiple resins in continuous form offer improved structural performance around stress concentrators and multi-functional capabilities, unlike traditional composite materials. As the process lacks vacuum assistance, porosity becomes a primary issue to be addressed. This paper presents a rheo-kinetic coupled rapid consolidation procedure for optimizing the quality of localised matrix patches. The procedure involves manufacturing trials and analytical consolidation models to determine the best processing program for minimal voidage in the patch. The results provide a step towards an efficient manufacturing process for designing multi-matrix composites without the need for complex vacuum bag arrangements. By optimizing the quality of the localised matrix patches, the procedure described in this paper can improve the overall performance of multi-matrix composite systems. The ability to create these composites without the need for complex vacuum bag arrangements can also reduce the manufacturing cost and time associated with the manufacturing of multi-matrix fibre-reinforced composites.
