Abstract
A rigid, shaped, mass support system, such as support or seating appliances for disabled or handicapped persons, is provided by charging a flexible container (2) made of elastic polymeric film with a uniform mixture of rigid particles of a mesh size relatively small compared to the size of the system and a curable adhesive polymeric binder material. The charged container (2) and its contents are molded to adapt to or fit the shape of the mass, such as the contour of that portion of the body to be supported, and evacuated to remove volatiles and fix the shape of the contents of the container. The adhesive binder is then cured to solidify the molded contents of the container to form a composite, from which the polymeric film can be stripped away, after which an adhesive paint is applied to seal and protect the surface.
