Title: Innovations of John Gillespie

Introduction

John Gillespie is a notable inventor based in Hockessin, Delaware, with a focus on advanced materials. He holds four patents, showcasing his contributions to the field of composite materials, particularly carbon fiber technology. His work emphasizes the importance of mechanical strength and electrical properties in material design.

Latest Patents

One of Gillespie's latest patents is for a composite carbon fiber material and the method of making it. This innovative material consists of one or more layers of carbon fiber, with the fibers aligned in the same direction. The composite includes a mat of nonwoven, woven, or off-axis unidirectional carbon fibers that are laminated together. The layers can be used individually or as a hybrid, and they can be preimpregnated or impregnated during processing with thermoplastic or thermosetting resins. A layer of thermoplastic resin is applied either over the surface or within the composite structure, allowing the resin to permeate the material. This process results in a more stable mechanical structure once the resin is processed. The material not only combines good mechanical strength but also improves electrical current-carrying properties compared to aligned carbon fiber layers alone. The layering sequence, layer type, and resin type can be tailored to enhance electrical properties, mechanical properties, durability, and wear resistance. Notably, this material achieves these results with a significantly smaller thickness than previously available options.
