Abstract
A method of preparing a continuous yarn from comingled discontinuous glass fiber and thermoplastic fiber is described. An exemplary yarn comprising comingled recycled glass fiber and acrylic fiber is described. Methods of preparing fiber-reinforced composite components from the yarn are also described. The fiber-reinforced composite components can be used in a variety of applications. In an exemplary application, the composite is used to provide component parts for a model rocket body and nosecone.
Claims25
