The present invention concerns a process for producing a thermoformable porous web using a mixture of cellulosic fibers and one or more thermoplastic materials, particularly by foam forming said mixture into a composite foam, and applying the foam into one or more layers on a support to obtain a porous pre-form web. The thus produced porous composite web can be further processed by compression molding to give a rigid high-strength composite structure, which is suitable for use in producing, e.g. panels or plates, packages or hygiene products, insulators or filters, or printed intelligence, electronics or microcellulose products.

The present invention relates to a new composite comprising cellulose-based fiber and polymer-based fiber as well as to a process for the preparation of the composite and molded articles made from said composite.
