STUDY ON THE FORMING PROCESS OF COMPOSITES FILLED WITH NOMEX HONEYCOMB SANDWICH STRUCTURE

Abstract

Abstract: In this paper, the edge dent is easily appeared in the curing process of bismaleimide resin matrix composite sandwich structure filled with Nomex honeycomb. The bismaleimide resin based carbon fiber laminate/honeycomb sandwich structures were developed by using different curing process, during which the co-curing process parameters were adjusted. The mechanical properties, internal quality and tensile properties of the sandwich structure were tested, based on which the influence of molding pressure on the sandwich structure quality was analyzed. The processing experiment shows that the edge dent of honeycomb core is mainly attributed to the local instable of honeycomb core resulted from the edge slipping of honeycomb core, during the cured process. It can be effectively solved by the method of step curing method and molding after bonded method of Nomex honeycomb core.

Key words: bismaleimide resin, carbon fiber composite, honeycomb sandwich structure, dent of honeycomb core
