A fibre-reinforced composite leaf spring based on the polyurethane matrix resin Loctite MAX 2 from Henkel is being used in the chassis of the new Volvo XC90. In its alliance with Benteler-SGL to develop large-scale production of a composite leaf spring for Volvo Cars, Henkel has contributed its process know-how in relation to RTM to further optimise the cycle times that occur in the manufacture of fibre-reinforced components.
Because of its low viscosity, the polyurethane matrix resin Loctite MAX 2 rapidly fills the mould and quickly yet gently impregnates the fibre material, resulting in short injection times, claims the company. With the curing rate also substantially faster than that of epoxy resins, cycle times are shorter overall.
