Title: John Michael Comfort: Innovator in Friction Stir Welding and Composite Structures
Introduction
John Michael Comfort is a notable inventor based in Corona, CA (US). He has made significant contributions to the field of engineering, particularly in friction stir welding and composite materials. With a total of 7 patents to his name, Comfort continues to push the boundaries of innovation.
Latest Patents
Comfort's latest patents include advancements in pin tool assemblies for friction stir welding. These assemblies consist of an outer member, an inner member, and a stop. The outer member features an inner surface that defines an elongate internal cavity, along with an external shoulder that includes an opening to this cavity. The inner member, which includes a welding end, extends partially within the cavity and projects from the opening, allowing the welding end to be external to the cavity. This design permits relative motion between the inner and outer members, while the stop defines various configurations that restrict this motion to establish a specific stop distance between the welding end and the external shoulder.
Another significant patent involves built-up composite structures with a graded coefficient of thermal expansion (CTE) for extreme environment applications. This innovation involves selecting multiple layers of materials with a graded CTE and employing bottom-up fabrication techniques, such as metal deposition or powder metallurgy. The result is a CTE-graded layered composite preform that is consolidated and heat-treated to create an integrated composite billet or near net shape, suitable for various structural applications.
