Title: Innovations of John G. Vollmer

Introduction

John G. Vollmer is a notable inventor based in Lomita, CA (US), recognized for his contributions to advanced composite materials. With a total of 4 patents, Vollmer has made significant strides in the field of engineering, particularly in applications that require materials to withstand extreme environments.

Latest Patents

One of his latest patents focuses on built-up composite structures with a graded coefficient of thermal expansion for extreme environment applications. This innovation involves creating an integrated composite structure by selecting various layers of materials with a graded coefficient of thermal expansion (CTE). The process utilizes build-up fabrication techniques, such as metal deposition or powder metallurgy, to produce a CTE-graded layered composite preform. This preform is then consolidated and heat-treated to create a CTE-graded integrated composite billet or near net shape, which is further processed to attach structural members with different CTEs.

Another significant patent by Vollmer is related to the reinforcement of friction plug welds. In this invention, a hole in a metal workpiece is filled through friction plug welding. The weld between the workpiece and the plug is enhanced by a weld land that surrounds one end of the plug, which is formed by extruding a portion of the plug into a cavity in an anvil during the welding process.
