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.
L'invention concerne des matières et des procédés destinés à produire des matières de préformes pour des matières composites résistant aux impacts convenant au moulage liquide. Des couches intermédiaires formées de fibres continues, non tissées, telles qu'une étoffe à ouvertures, un non tissé lassé par filage, ou un tissu non tissé, placées entre des couches non crêpées de fibres à renforcement unidirectionnel permettent d'améliorer une préforme utilisée dans des traitements de moulage liquide afin de produire un élément composite. Le durcissement de la préforme fournit une résistance aux impacts améliorée par augmentation de la quantité d'énergie requise afin de propager des caractéristiques localisées provoquées par l'impact.
