ABSTRACT:
The specification discloses an unorthodox system for manufacturing strong, light-weight and weather-resistant cellulosic composite materials from discarded paper and newsprint, and papermill sludge--and from an unlimited variety of particulated fibrous lignocellulosics--without the use of an extrinsic adhesive. Both the matrix-forming resin and the fiber-substrate, which comprise the entire composite, are spontaneously created in situ at ambient conditions by the ammoniation of a mixture of a protein-containing material and a particulated cellulosic. Heating an article shaped from such a mixture to above 175.degree. C. polymerizes the resin and bonds the fiber-substrate into a cellulosic composite product. Also disclosed is a process for manufacturing reinforced and laminated composites as well as a composition which simplifies the production of both cellulosic composites and all-biomass thermosetting resins.
