HOT-PROCESSING ASSISTED PREFORM TECHNOLOGY FOR SUPER-THICKCOMPOSITE LAMINATE BY VARI PROCESS

Abstract

Abstract: Represented by VARI process, the liquid composite molding technology has caused more and more research attention. This article focused on the VARI technology for super-thick composite part and creatively put forward the hot-pressing assisted preform technology. We took 100-layer super-thick laminate by VARI process for example, introduced hot-pressing in the preform manufacture process, and investigated its influence on the thickness of the preform, the resin injection and outlet placement and the quality of the cured composite part. Our work has positive significance for improving the fiber volume content, the performance of the VARI composite parts and the development of the application of VARI technology in aircraft structure. The results will provide reference for the design and application of thick composite parts by VARI manufacture process in aircraft structure.

Key words: hot-pressing assisted, preform, super-thick laminate, VARI
