Axson Technologies’ (Cergy, France) new technologies included a new reusable silicone bagging concept with an integral heating insert. The vacuum bag or countermold is created by first spraying the company’s SVB 20 silicone material to match the tool. Next, small electrical heating wires supplied by Flexelec (Saint Bonnet de Mure, France) are embedded in the material while it cures, offering cost savings by eliminating expendables while targeting mold heating in key areas for complex shapes. Also on offer: Epolam 2040, a new epoxy system for large parts made via resin infusion, such as wind blades, that reportedly delivers good mechanicals. The Germanischer Lloyd-approved system has low viscosity, enabling thorough wetting of reinforcements, and it features a choice of slow to fast hardeners for tailored processing time.
