Study Of Processing Parameters In Manufacturing Of Flat Glass-Epoxy Composite Laminates Using Vacuum Bagging Oven Curing

The effective manufacturing process for aircraft structural parts made from composite laminate usually involved autoclave prepreg material manufactured via vacuum bagging pre-forming and autoclave. Though, autoclave involves high capital, running cost and extortionate residual stress. Vacuum bagging...
