Abstract
Abstract The invention is based on the discovery that texturized cellulosic and/or lignocellulosic materials can be combined with many different matrix materials, including organic matrices (e.g., thermosetting resins, elastomers, asphalts, lignins, or tars) to produce useful compositions.
