  • Patent number: 11655353
    Abstract: A sheet molding compound (SMC) is provided with superior conductivity properties based on the use of graphitics. A process for exfoliation of GnP and turbostratic carbon is also provided. By exfoliating the graphitics, a reduced amount of material can confer comparable properties relative to native GnPs or turbostratic carbon thereby reducing the amount of material usage, but also reducing negative effects to the base resin formulation through inclusion of these additives. Particular utility is found in thermoset resin molding to produce articles that are amenable to electrostatic coating and other surface treatments that rely on surface conductivity and especially in the realm of vehicle body parts.

  • Patent number: 11597242
    Abstract: A radial tire (10), with the sidewalls thereof (20), and the tread thereof (30) arranged for minimizing the temperature of the tire while guaranteeing its electrical conductivity. The tread (30) comprises two wings (311, 312) and a central portion (32). These components rest on a base layer (33) radially on the inside of the tread (30). The base layer (33) contains a lateral portion (331, 332) partly in contact with a tread wing (311, 312). This structure of the crown of the tire, in contact with the carcass reinforcement makes it possible to constitute a preferential conductive pathway of the electric charges between the rim and the ground when the tire is mounted on its rim and flattened on the ground.
