The limits of vacuum infusion technology during the production of filled polymer composite systems

Abstract

The vacuum infusion process (VIP) is suitable for production of bigger prototypes and low-series production, but their utilization is increasing because their low investment cost, comparability with high-tech technology (pre-preg), possibility to produce sandwich structures in one step and many various advantages. We verify the possibility of VIP to produce various prototypes with increasing degree of flame retarders, specifically aluminium hydroxide (ATH), which fulfil regiments to mechanical and Fire-Smoke-Toxicity (FST) properties according EN 45 545. Mechanical properties we confirmed by testing of bending properties according EN ISO 178 and tensile properties according EN ISO 527-4. FST properties were confirm by flammability test with hot wire according EN ISO 60695-2-11. © 2018 Trans Tech Publications, Switzerland.
