Introduction

Boyd A. Barnard is a notable inventor based in St. Louis, MO (US). He has made significant contributions to the field of materials science, particularly in the development of advanced laminates. With a total of 5 patents to his name, Barnard's work showcases his innovative approach to solving complex engineering challenges.

Latest Patents

Among his latest inventions is a pressure-sensitive adhesive laminate. This invention relates to improved polymer-pressure sensitive adhesive combinations, particularly in the form of laminates, and methods of producing the same. It enhances the bond strength of the pressure-sensitive adhesive to the polymer layer by priming the polymer surface with a curable urethane primer before applying the adhesive. If the polymer surface is not 'active' to the curable urethane primer, it is first activated with a silicon-containing treating agent. The laminates developed through this invention exhibit superior bond strength, especially in long-term applications. Notably, the polymer can be a silicone foam, while the pressure-sensitive adhesive may be either acrylic or silicone-based.

Another significant patent is for a heat barrier laminate. This lightweight and resilient laminate provides sound and vibration dampening. It has a density of less than about 5 lb/ft³ and a total thickness of no greater than about 1 inch. The laminate consists of a first metal foil with high heat conductivity and a first batt of insulating nonwoven fiber material. The first batt serves as the outermost layer, adhesively bonded to one side of the metal foil. Additionally, it includes a second metal foil and a second batt of insulating nonwoven fiber material, which is thicker than the first batt. This innovative design allows for effective heat management and sound dampening.
