In simple sealed moulds, glass fibre reinforced plastic components that are smooth on both sides are produced cost-effectively under a vacuum in comparatively short cycle times. The production of sandwich components resistant to bending, with a foam core, and the direct integration of metal reinforcements and threaded elements – for example for large vehicle components – has also proven itself. Typical properties Dense matrix / composite of approximately 0.6–0.7 g/cm³ / 0.7–1.2 g/cm³ Fibre content 20-50% of total weight Moulded part mass per unit area of 3000–5000 g/m² Flexural modulus of elasticity 3000–8000 MPa Bending resistance of 35–185 MPa Impact resistance of 35–65 KJ/m² (with 20–35% glass content) Reinforcing materials: Continuous glass fibre mats Composite glass fibre and fleece mats Natural fibre mats Special formulations and versions Systems with long processing times for very large components Foam resin formulations with elevated dimensional stability under heat Systems for fibre-reinforced components with a high level of characteristics Coordination with gel coat / top coat for surface refinement Flame protection formulations Electrical industry: UL 94 V0 Rail vehicle construction: DIN 5510 (S4, SR1, ST2)
