Innovative powerboat hull uses composites

Unique British fibreglass powerboat, The Bladerunner, was fabricated using Scott Bader Crystic products.

Bladerunner powerboats are individually hand built to order by ICE Marine. They use both open mould hand lay-up and vacuum bagging processes.

The Bladerunner BR RIB35 laminate design uses a Lloyd's approved Scott Bader matched marine system. This comprises of pigmented Crystic 65PA isophthalic gelcoats used in combination with Crystic 489PA isophthalic unsaturated polyester back-up resin.

Depending on the Bladerunner model and specification required laminate constructions use a combination of chopped strand matting, biaxial and unidirectional glass and carbon fibre fabrics, as well as mainly using DIAB's Divinycell H80 and H100 PVC foam cores. Sandwich laminate sections are used extensively in the structural design of both the hull and deck.

To achieve the highest long term mechanical performance of the laminate sandwich structures in key stress areas, PVC foam cores are first primed using a light coating of catalysed Crystic 489PA resin and then bonded in with Crystic Crestomer 1196PA, a low density gap filling structural adhesive specially designed for core bonding.
