Title:
真空注入法によって製造したポリウレタン複合材料
Document Type and Number:
Japanese Patent JP2014508850
Kind Code:
A
Abstract:
A polyurethane-forming system having a viscosity at 25° C. of less than 600 mPas for at least 30 minutes, a gel time at ambient temperature of greater than 60 minutes and a water content of less than 0.06% by weight, based on total system weight, is used to produce composites by a vacuum infusion process. This system makes it possible to produce large composites such as wind turbine blades having excellent physical properties.
