Touchstone Research Laboratory has been developing several processing techniques for manufacturing large metal matrix composite components in an affordable manner. The goal is to create a fiber reinforced metal industry based on polymer composite manufacturing processes and, where possible, utilizing PMC equipment. Several processes are under development, utilizing Touchstone’s MetPreg™ technology, that are analogous to those used for producing polymer matrix composite structures. These include hand lay-up processes such as vacuum bagging and automated processes such as tape placement. Other processes are also under development. This technology has the potential for the end user to manufacture MMC parts one day and PMC parts the next on an existing piece of equipment. This paper describes Touchstone’s current efforts to advance this unique technology.
