APCM DA 4518U/E-Glass Unidirectional E-Glass Epoxy Prepreg
Categories:	Polymer; Thermoset; Epoxy
Material Notes:	Description: A 4518U/E-Glass Uni is a modified epoxy system coated on heavy weight unidirectional E-Glass fibers. This product is designed to build excellent unidirectional strength using a mini-mum number of plies. DA 4518U/E-Glass Uni also features extended room temperature out-time and service temperatures to 300°F. Mechanical Properties: Cured: The cured properties were obtained using a press cure of two hours at 275°F with 25 psi followed by a post cure of 350°F for 4 hours.
