Pre-preg curing - I have had a quick look through the easy composites pre-preg offering and was surprised to find fairly basic information regarding the resin systems used and the cure process. Not anywhere mentioned is the recommended ramp rate for cure which is extremely important. As a general rule of thumb anywhere from 0.3C to 2C per minute is acceptable but this really depends on the application and should be specified by the manufacturer. Ramp rates allow the resin to flow correctly eliminating pin holes and voids and it allows the cured resins tg1 to stay ahead of the 'cure'.
