Abstract: Modular Infusion is a novel liquid resin moulding method which aims to decrease variance across components, reduce frequency and magnitude of flow-based defects and enable fibre or matrix design optimisation. The term ‘modular’ refers to segregating independent zones during a single liquid resin moulding process so that a predictable and preferential flow front progression is developed.
In the work presented mechanical impact of introducing modular regions in components is explored and de-risking capabilities are further assessed through a larger, more complex demonstrator component. Barrier film segregation was studied using T-stiffener pull off test, which indicated comparable performance to traditional manufacturing techniques, as well as more predictable mechanical performance and enhanced opportunity for repair. Three-point bend testing revealed an unexpected rise in flexural strength and change in failure mode with no significant change in modulus. Micrometre, ultrasonic thickness, and modulus measurements demonstrate the success of a volume fraction normalising process applied post compaction barrier application. X-ray computed tomography (XCT) analysis of demonstrator components revealed superior quality of components fabricated through modular infusion processes.
