This invention relates to a composite material comprising a core comprising an organosilica such as a polyhedral oligomeric silsesquioxane (POSS) and a functionalized elastomeric polymer such as poly(n-butyl acrylate) bonded onto said core. The elastomer is preferably functionalised with an amine moiety. The present invention also relates to a polymer comprising a resin such as Bisphenol A diglycidylether (DGEBA) and the aforementioned composite material, and a method for making the composite material. The composite material can improve both the material strength and material toughness of the polymer into which it is mixed.
