William K Oehlert, Deceased

Title: William K. Oehlert and Acid-Resistant Composite Manufacturing

Introduction

William K. Oehlert, a deceased inventor associated with Helotes, Texas, contributed to composite manufacturing through a patented method for making metal surfaces substantially impervious to acid. His work is associated with Northrop Grumman Systems Corporation.

Latest Patents

Oehlert’s listed patent, “Acid Impervious Coated Metal Substrate Surface and Method of Production,” describes coating a metal substrate with high-temperature-resistant polymer particles, such as polyamide, and a curable powder adhesive. The coated substrate is then cured so the adhesive bonds the particles into a protective film.

The method is intended to produce steel fixtures for curing resin-impregnated fiber composites. Composite material can be vacuum-bagged to the fixture and cured in an autoclave. The acid-resistant coating helps prevent iron from leaching from the fixture into the composite, supporting the fabrication of usable parts. Oehlert is credited with 1 patent.

Career Highlights

Oehlert’s documented patent work focuses on a practical challenge in composite production: protecting metal curing fixtures during elevated-temperature processing. The coating method combines a durable polymer layer with an adhesive that can be cured onto the substrate.

Collaborations

The supplied information identifies Northrop Grumman Systems Corporation as Oehlert’s company affiliation and names Jerry Wynn Brimer and Ernie Robert Silva as coworkers. These details provide context for his professional associations, though they do not establish specific roles in the patent.

Conclusion

William K. Oehlert’s patent describes an acid-resistant coating process designed to protect steel fixtures and support reliable composite-part manufacturing.
