Title: The Innovative Contributions of Joseph P Coyle

Introduction

Joseph P Coyle is a notable inventor based in Warren, MI (US). He has made significant contributions to the field of friction materials, holding a total of 3 patents. His work focuses on the development of advanced brake pad technologies, which are essential for automotive safety and performance.

Latest Patents

Coyle's latest patents include a groundbreaking invention for a molded brake pad. This invention involves a unique composition of materials designed for use as friction material in brakes. The process begins with the addition of liquid double salts of dibasic and monobasic (ammonium-potassium hydrogen) phosphoric acid to a dry mixture of reinforcing fiber, friction modifiers, fillers, and phenolic resin. This combination creates a high viscosity slurry that is then molded into the desired shape. The metallic oxide reacts with the double salts, while paraformaldehyde interacts with the phenolic resin, forming a robust two-binder matrix that secures the components in place. The brake pads are subsequently cured in a ventilated chamber to complete the manufacturing process.

Another significant patent by Coyle is a method of manufacturing a friction article. This method utilizes a fiber material that contains a continuous and uniform three-dimensional matrix filled with a slurry of fillers, friction modifiers, reinforcing material, and a liquid binder. The filled fiber material undergoes drying to remove volatile solutions, leaving behind a solid structure. It is then placed in an oven where compressive force is applied, allowing the binder to cure and form a stable matrix that holds all components together.
