DIAB (Desoto, Texas) has added to its Divinycell HP range of core materials a low-density version, HP60. It offers a nominal density of 65 kg/m3 (4.1 lb/ft3) and will allow further weight reductions in advanced sandwich composite structures. The product is targeted to the wind energy and marine markets, particularly in applications using prepregs. According to the company, the material's compressive strength and modulus are sufficient to resist the buckling loads experienced by wind blades, and its high service-life temperature makes it suitable for dark colored decks and superstructures. It also features a processing temperature of up to 140°C/284°F with good adhesion and peel strength and is fully compatible with the majority of epoxy prepregs. It can also be used in closed molding processes, such as resin infusion and RTM.
