Italian boat builder Cantieri di Baia recently used composite materials from SP, the marine business of Gurit, in the design of its latest additions to the Baia 50 range.
A selection of SP materials, supplied by SP’s Italian distributor Resintex Technology, was used on the new Baia 50 which is being launched at the Genoa Boat Show later this month. Materials include Corecell, the structural foam core, and SP’s adhesive, laminating and epoxy systems.
Manufacturers say that Cantieri di Baia chose to make the switch from polyester and vinylester to SP’s epoxy for the build of the Baia 50 because epoxy resin systems are now being consistently adopted for high-performance structures requiring ultimate weight efficiency and durability.
According to SP, the PRIME 20LV epoxy system, specially designed for infusion technology, was used because of its low viscosity which contributes to short infusion times and optimum fibre impregnation, as well as providing very good stiffness properties and an excellent laminate quality. The switch was an effective solution for the new Baia 50, with tests carried out by Cantieri di Baia estimating a resulting weight reduction in the order of 25% out of 4.2 tonnes of structural weight for the hull.
As Cantieri di Baia were looking for a hand layup laminating system, they chose Ampreg due to their their low viscosity, which makes them ideal for wetting out heavyweight fibres. Sp say that Ampreg is particularly good for secondary bonding applications, due to them giving good laminate quality, making them ideal for the manufacture of large, high performance composite structures.
Spabond 340LV and Corecell T400 were also used in the build.
Paul Riley, Technical Sales at SP, said: “As the boatbuilding community and its clients become more and more confident with the performance advantages of epoxy resin – both in terms of structural and cost characteristics – we are witnessing a steadily increasing number of production boatyards, like Cantieri di Baia, switching from polyester or vinylester to epoxy systems for their manufacturing.”
