A reinforced polyolefin composite is provided. The reinforced polyolefin composite comprises a polyolefin such as polyethylene or polypropylene, a rigid fibre micro filler such as glass fiber, carbon or cellulosic fibers, and at least one nano filler such as clay. The reinforced polyolefin composite may also comprise a modified polyolefin, which has a polar functional group such as maleate monoester, an acid anhydride or an acrylate grafted thereon. The clay nano filler may also be modified with an organosilane. The reinforced polyolefin composite may also comprise a stabilizer or other additives. A method of producing the reinforced polyolefin composite is also provided, comprising mixing a polyolefin, a rigid micro filler and at least one nano filler to form a mixture, melting the mixture and kneading the melted mixture. The obtained reinforced polyolefin composite is used in transportation, infrastructure, consumer goods and construction.

Reinforced polyolefin composite

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.
