Abstract

A novel net-shape manufacturing process for polymer-particulate thermosetting or thermoplastic composite products has been developed, which enables, at near maximum packing density, perfect product-wide particulate uniformity with no particulate agglomeration. The process consists of the following "unit operations": (i) fluidized bed particle coating with UV-curable composition to impart particulate flowability and eliminate agglomeration (ii) pouring and packing of the particulates into a vessel having the same dimensions as the composite product (iii) infusion of a polymerizable low viscosity liquid into the particulate bed packed in the vessel, assisted by vacuum on the packed bed and pressurization of the liquid, followed by polymerization of the infused liquid to form a polymer thermoplastic or thermoset matrix.
