Title: Innovations by Dean Nguyen

Introduction

Dean Nguyen is an accomplished inventor based in Stamford, Connecticut. He has made significant contributions to the field of composite materials, particularly in the aerospace industry. With two patents to his name, Nguyen's work focuses on innovative fabrication processes that enhance the efficiency and effectiveness of composite components.

Latest Patents

Nguyen's latest patents include a "Fabrication process for composite swashplate" and a "Removable irreversibly shrinking male mandrel." The first patent describes a method for fabricating a composite swashplate ring using a thermoplastic expandable mandrel. This mandrel remains rigid during the braiding process but softens after resin impregnation, allowing for expansion in a mold to improve fiber consolidation. This innovative approach enables the production of a net-shaped composite swashplate ring without the need for machining.

The second patent introduces a shrinkable foam mandrel that can be easily removed after the composite resin transfer molding process. This foam is dimensionally stable at the cure temperature of the composite resin and can irreversibly shrink to less than half its original size at a higher temperature. Encapsulated by a non-stick elastomer skin and covered with fibers, this mandrel addresses the aerospace industry's flyaway mandrel problem by being lightweight and easily removable from the composite component.
