Patent number: 8852713Abstract: Materials and methods are provided for producing preform materials for impact-resistant composite materials suitable for liquid molding. Interlayers formed of nonwoven, continuous fibers, such as spunbonded, spunlaced, or mesh fabric, are introduced between non-crimped layers of unidirectional reinforcing fibers to produce a preform for use in liquid-molding processes to produce a composite member. Curing of the preform provides increased impact resistance by increasing the amount of energy required to propagate localized fractures due to impact.Type: GrantFiled: July 30, 2012Date of Patent: October 7, 2014Assignee: The Boeing CompanyInventor: Thomas Karl Tsotsis
