Wind-turbine rotor blade with good abrasion-resistance

摘要

A multilayer composite component for the rotor blades of wind turbines has been developed by Wobben Properties. Disclosed in US Patent US2019/0263096, the component, a leading rotor-blade edge, is claimed to demonstrate high abrasion-resistance and therefore improved longevity compared with those employed on conventional blades. Further, it can be produced in a relatively short time and at low temperatures, says the company of Aurich, Germany. The composite component comprises: 1 a first layer (surface foil) (11) consisting of polyethylene (PE), such as ultra-high molecular weight polyethylene (UHMWPE); 2 a second layer (12) consisting of an elastomer, such as an ethylene propylene diene monomer (EPDM) rubber; 3 a third layer (13) consisting of a thermoset or thermoplastic, such as an epoxy-based polymeric resin system.
