A method of fabricating a composite material can include adding particulate material to an elastomeric material. The particulate material can include expanded graphite particulates and/or graphite nanoplatelet particulates. The particulate material can be diffused within the elastomeric material to uniformly disperse the particulate material within the elastomeric material. The elastomeric material having the particulate material dispersed therein can then be cured after the diffusing to form a structure comprised of the composite material, the composite material including the elastomeric material and the particulate material. In some embodiments, surfaces of the particulate material can be modified to include carboxyl and hydroxyl groups before the particulate material is added to the elastomeric material to facilitate improved bonding of the particulate material. In some embodiments, the formed structure can be configured as or for use in a gasket, seal, vibration dampening device or sound reduction device.

The purpose of the present invention is to provide: a thermoplastic resin composition which exhibits excellent rigidity, while having excellent impact strength characteristics; and a method for producing the thermoplastic resin composition. This thermoplastic resin composition, wherein a polyolefin resin contains a polyamide resin that is dispersed therein, is characterized in that: the thermoplastic resin composition is obtained by melting and kneading a polyolefin resin and a mixed resin that is obtained by melting and kneading a polyamide resin and a compatibilizer; and the compatibilizer is a modified elastomer that is obtained by providing an elastomer (such as an olefin-based thermoplastic elastomer or a styrene-based thermoplastic elastomer) with a reactive group that is reactive with the polyamide resin.

The invention relates to a process for preparing a rubber composition which comprises an elastomer matrix which includes natural rubber and a synthetic diene elastomer, a modifying agent comprising a nitrile oxide dipole and an N-substituted imidazole function, a reinforcing filler comprising more than 50% by mass of a silica, a silane coupling agent and a vulcanization system, which process comprises prior kneading of the elastomer matrix alone before proceeding with the non-productive and productive kneading steps. The process enables a good compromise between the properties of hysteresis and stiffness and the amount of modifying agent.
