发明名称 METHOD AND PREFORMS FOR FORMING COMPOSITE MEMBERS WITH INTERLAYERS FORMED OF NONWOVEN CONTINUOUS MATERIALS
摘要 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.
