These non-adhesive pre-preg thermoset composites (b-stage products) are non-tacky and dry to the touch. Therefore, they do not require the release film found on conventionally tacky pre-pregs. These high-performance pre-preg composites continue to provide the same flow and bonding performance as traditional materials and can be customized to fit a diverse range of requirements. Available substrates include glass, cotton, paper, carbon fiber and customer-specific substrates; resin systems include phenolic, epoxy, melamine and specialty. According to the company, their computer-controlled factory processes maintain tight resin/substrate ratios for consistent reactivity.
