A polyurea additive is provided that strengthens a given base sheet molding composition (SMC) An isocyanate containing species and an amine containing species are introduced into an uncured polymeric resin of a sheet molding compound (SMC) under conditions suitable for the formation of a polyurea polymer network. Upon cure of the SMC base resin, an interpenetrating network is formed that is stronger than the base SMC absent the polyurea. As a result, an article is formed from the SMC that is stronger at the same dimensions than a conventional article or thinned to achieve the same properties to obtain a lightweight article compared to that formed from conventional SMC. The properties of the article are also attractive relative to aluminum for the formation of vehicle body and exterior panels.

A liquid dispersion made by a process is disclosed. The process includes forming multicellular networks having a diameter of 1,000 μm or smaller by at a temperature of 1100° C. or less, in the presence of a powder of template particles, forming carbon shells, each of the carbon shells generally encapsulating a template particle and together with the encapsulated template particle comprising a heterostructure. The heterostructure comprises a particle diameter of 1,000 μm or smaller and a morphology of interconnected structural subunits and, between the structural subunits, exohedral pores.
