Abstract

This work aims to demonstrate one such case, where the gel coat is substituted for a polyester veil (in this case a patterned wood effect) and a novel UV resistant resin, employing a closed moulding infusion process. Different types of surface veil were investigated on the basis of their finish quality and drapability around concave corners. Three resin types by Scott Bader (9933PA, 936PA, and 196) were selected for UV resistance development, and novel blends of the three subjected to accelerated weathering tests through UV irradiation and moisture cycles in accordance with ISO 4892-2 and ISO 4892-3. Finally, a demonstrator part was produced to assess the suitability of the approach of the veil and 9933PA resin blend as a closed moulding, relative to typical approaches. Initial results suggest increases in productivity are possible through the approach, whilst aesthetically improved capability and performance is gained.
