Bio-chemical specialist Elmira (London, U.K.) has released a range of prepregs that feature bio-based resins, available with a selection of reinforcements, including carbon fiber, E-glass fiber and naturally derived fiber alternatives. These materials are suitable for a range of processes and curing requirements, exhibiting good resin flow and cured-laminate quality. The company claims the materials provide curing characteristics and, in postcure use, thermal stability and mechanical performance comparable to conventional epoxy-based prepregs, and they also impart increased impact strength along with better water and chemical resistance.
