Developed within the Clean Sky initiative, liquid resin infusion enables the manufacture of large structures from composite materials. EU-funded researchers have now developed numerical models that will help optimise the process based on a solid scientific base.
Liquid resin infusion has been proposed for high-quality stiffened structures such as wing spars, wing skins and panels for the centre wing-box. Executed out of the autoclave – i.e. without pressure – this innovative process can use composite materials in a way that reduces manufacturing costs as well as components' weight.
