Continuous fiber reinforced composites are used in a variety of aerospace, automotive and industrial applications. The ability of thermoplastic composites to be melted and subsequently resolidified allows joining processes such as vibration welding to be used. In this research, vibration welding was used to join polypropylene plates reinforced with woven glass fibers. The effect welding parameters, such as meltdown, weld pressure and weld geometry were investigated. Vibration welding is shown to join highly reinforced composite materials with weld strengths approaching those of short fiber composites.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
