A thin, tacky, non-pourable film of incompatible in situ-expandable thermoplastic particles and thermosettable matrix resin that contains an essentially uniform density and thickness across the breadth of the film. The in situ-expandable mass is not pourable yet can be easily dispensed in a uniform manner within a mold and thereafter expanded to the dimensions of the mold. Composites and reinforced compositions, as well as methods of molding, are disclosed.
Pellicule mince, poisseuse et non coulable de particules incompatibles thermoplastiques extensibles in situ et de résine d'enrobage thermodurcissable dont la densité et l'épaisseur sont essentiellement uniformes sur toute la largeur de la pellicule. La masse extensible in situ est non coulable bien qu'elle puisse être facilement déposée dans un moule qu'elle remplit en prenant de l'expansion. L'invention porte également sur des matériaux composites, des composites renforcés ainsi que sur des méthodes de moulage.
