Fabrication of the Cabin Component by Flexible-mould Assisted RTM Process and Its Performance

ZENG Jing-cheng,YIN Chang-ping,LIU Jun(College of Aerospace and Material Engineering,NationalUniversity of Defense Technology,Changsha 410073,China)  
Some equipment components with large size and complicated internal structures were difficult to be manufactured integrally in one time by traditional RTM process.These components fabricated by traditional RTM had poor mechanical properties because the fiber volume fraction was very small.In this paper the complicated flexible-mould was fabricated with silicone rubber.The silicone rubber mould was used to assist RTM to manufacture the cabin component.The surplus resin were squeezed out when the flexible-mould expanded by heating,therefore the fiber volume content of the composites reached 57% and the mechanical performance of the composites improved much.The static mechanical properties of the cabin satisfied the requirements of the primary load bearing structure in aerospace,so the flexible-mould assisted RTM process that was suitable to manufacture the components with complicated inner shape was prosperous in fabricating equipment components.
