CA 2566447

Prepreg compositions comprised of fibers and a prepreg resin, comprising a thermosetting resin, a curing agent, and a plurality of thermoplastic polymers, in which greater than 10% of each of the thermoplastic polymers are soluble in the prepreg resin, are useful for making composite materials. In preferred embodiments, the prepreg compositions are used as self-adhesive prepregs for making honeycomb structures useful for various high performance applications.

L'invention concerne des compositions de préimprégné qui comprennent des fibres et une résine en préimprégné, renfermant une résine thermodurcissable, un agent de traitement et plusieurs polymères thermoplastiques, sachant que plus de 10 % de chaque polymère sont solubles dans la résine. Les compositions sont utiles pour l'élaboration de matériaux composites. Selon des modes de réalisation préférés, les compositions sont utilisées comme préimprégnés auto-adhésifs pour l'élaboration de structures en nid d'abeille utiles pour différentes applications haute performance.
