Publication number: 20110021737Abstract: Methods of making a fiber-reinforced composite article are described. The methods may include providing fibers to an article template, where the fibers have been treated with a coupling-initiator compound. They may further include providing a pre-polymerized mixture that includes a monomer and a catalyst to the article template. The combination of the fibers and the pre-polymerized mixture may be heated to a polymerization temperature where the monomers polymerize around the fibers and form at least a portion of the composite article. The article may then be removed from the article template. Examples of the fiber-reinforced composite articles may include wind turbine blades for electric power generation.Type: ApplicationFiled: September 14, 2010Publication date: January 27, 2011Inventors: Rajappa Tadepalli, Jawed Asrar, Klaus Friedrich Gleich
