Title: Innovations by David J Hezzell
Introduction
David J Hezzell is a notable inventor based in Biggleswade, GB. He has made significant contributions to the field of materials science, particularly in the development of fibre-reinforced compositions. With a total of four patents to his name, Hezzell's work focuses on enhancing the properties of thermoplastics through innovative processes.
Latest Patents
Hezzell's latest patents include advancements in fibre-reinforced structures that comprise a thermoplastics polymer. These structures contain at least 30% by volume of reinforcing filaments that extend longitudinally. The unique aspect of his inventions is the continuous process used to produce these structures, which results in exceptionally high stiffness. This high stiffness is achieved through thorough wetting of the reinforcing filaments by molten polymer. The resulting product can be further processed in vigorous mixing processes, such as injection moulding, while retaining a surprisingly high fibre length in the final article. His continuous processes utilize thermoplastics polymers with lower melt viscosities than those conventionally deemed suitable for achieving satisfactory physical properties.
