MULTIAXIAL NON-CRIMP FABRICS HAVING A POLYMER NON-WOVENS

摘要

The present invention relates to a woven fabric made of at least two laminate layers made of multifilament reinforcing yarns arranged parallel to one another, said woven fabric comprising at least one layer of at least one nonwoven fabric made of a thermoplastic polymer material Wherein the non-woven fabric comprises a first polymer component and a second polymer component, wherein the melting temperature of the components is selected from the group consisting of melting of the reinforcing yarns Wherein the first polymer component has a lower melting temperature than the second polymer component and the first polymer component is selected from the group consisting of an epoxy matrix resin, a cyanate ester matrix resin, or a benzophthalimide matrix resin or a mixture of these matrix resins Wherein the second polymer component is an epoxy matrix resin, cyanate And the ester matrix resin or matrix resin or l, characterized by not soluble in the mixture of the matrix resin. The present invention also relates to preforms made of this type of woven fabric.
