BGF Industries (Greensboro, NC, US), a global manufacturer of woven and nonwoven materials from high-performance fibers, has launched PolyPreg, a woven co-mingled glass/polypropylene fabric that can be directly consolidated with the addition of heat and minimal pressure into a high-strength composite part. BGF says the material is soft and conformable to complex shapes, and available at 750 gsm in natural or black colors. Laminating, molding or pultruding processing conditions are recommended at a temperature of 400°F, with a cooling pressure of 20-100 psi. With an unlimited shelf life PolyPreg requires no cold storage and can withstand temperatures up to 300°F. UV stable in nature, the material maintains its color and form upon exposure to sunlight and is less likely to become brittle, crack or become discolored. PolyPreg is the first material from the DryPreg product line. DryPreg products currently in development will combine other high-performance fibers and resin systems to offer a varied line of thermoplastic composite materials.
