Mid-Temperature component prepreg for woven and unidirectional
RP542-4 is a controlled flow, toughened epoxy prepreg system formulated for the manufacture of high performance structural composite parts requiring very good impact strength properties. The system has been formulated for a medium temperature cure of 80 - 120°C under vacuum or autoclave pressure and is also suitable for press moulding. Fully cured, this system has a dry service temperature capability up to 120°C. The component surface finish with this system is excellent.
