High-pressure resin transfer molding (HP-RTM) is a modernization of conventional resin transfer molding (RTM). HP-RTM combines hot compression molding with resin injection. A dry pre-consolidated preform is inserted into the mold mounted in the press. Once the press is closed and at the right temperature, the specifically developed HP-RTM resin is injected, filling the tool and flowing all throughout the preform. HP-RTM processes allow for lower cycle times, excellent structural performance, complex geometries, and highly automated production. Typical applications of HP-RTM are serial manufacture of automotive body structure components such as floor pans, sidewall panels, crush cans, and bulkheads.
CCC houses an automated HP-RTM machine with a 1,000-ton press, as well as an advanced doser unit to support research and development for large-scale industrial production. Designed with industry equivalents in mind, Clemson’s HP-RTM results can be directly applied to manufacturing floors today.
