Latest Patents

One of Krug's latest patents is focused on "Graphene nanoplatelet modified sheet molding compositions." This invention provides a sheet molding compound (SMC) with superior conductivity properties through the use of graphitics. The process involves exfoliating graphene nanoplatelets (GnP) and turbostratic carbon, allowing for a reduced amount of material to achieve comparable properties to native GnPs. This innovation not only minimizes material usage but also reduces negative effects on the base resin formulation. It is particularly useful in thermoset resin molding for producing articles that are suitable for electrostatic coating and other surface treatments, especially in vehicle body parts.

Another significant patent by Krug is related to "Recycling carbon fiber based materials." This process enables the reclamation of carbon fiber from cured vinyl ester, crosslinked unsaturated polyester, or epoxy thermoset matrices. By adding composite pieces to a polyol solvent composition, more than 95% by weight of the carbon fiber can be freed from the composite. The reclaimed carbon fibers can then be washed and dried for reuse in reinforcing polymers to create new fiber-reinforced composite articles. The solvents used are chosen for their low cost and low toxicity, and the process is enhanced by techniques such as solvent pre-swell, microwave heating, and sonication.
