PREPREG MANUFACTURING AND DRYING PROCESS

摘要

Prepregs are prepared by impregnating a fiber mat with an aqueous dispersion of a thermosetting resin. The resulting wet, impregnated fiber mat is dried by contacting it with streams of elevated temperature gas, such as in an air flotation dryer. This process provides thorough and economical drying without significantly curing the thermoset resin.
