Dow Automotive Systems (Auburn Hills, Michigan) has developed VORAFUSE epoxy intermediates, which, when combined with carbon or glass fiber fabric, are said said to offer improved handling and rapid cycle times for compression molding of composite parts for structural applications. Commercialized on a front roof header in 2016, VORAFUSE is designed to work in processes like compression molding to achieve fast cycle times. It can be cured in 2 to 5 minutes for high-volume manufacturing and can be used to enable automated manufacturing solutions. A variety of fabric configurations will accommodate VORAFUSE, including unidirectional tape as well as woven, braided or non-crimp fabric in a range of areal weights. Available in two grades, the VORAFUSE P6300 resin system is designed for high-volume manufacturing with no tack for robot handling of 2D and 3D preforms and compression molding. VORAFUSE P6100 is formulated to accommodate diverse manufacturing scenarios from autoclave to out-of-autoclave processing on lower-cost tooling for medium to low volume applications.
