Title: Gregory L Fillman: Innovator in Composite Material Structures

Introduction

Gregory L Fillman is a notable inventor based in Renton, WA (US). He has made significant contributions to the field of composite materials, holding 2 patents that showcase his innovative approach to engineering solutions.

Latest Patents

His latest patents include an "Attachment fitting for composite material structures" and a "Fitting assembly for a composite structure." The first patent describes a load-bearing attachment fitting designed for composite material structures. This fitting features an elongate body with undulations that engage the fibers in the fiber-resin matrix, effectively transmitting loads from the fitting into the structure. The connection is formed using longitudinal strips of fiber-resin tape, which are laid over the fitting and the adjacent form. Crosswise fibers are then wound over the tape to ensure that the longitudinal fibers conform to the undulations, allowing for effective load transmission. A fluidizable form can be used to create the structure, and after curing, it can be removed through a threaded bore in the attachment fitting, which also serves as a mounting point for further assembly.

The second patent outlines an apparatus and method for securing fittings to composite structures made from resin-embedded fibers. This invention utilizes support structures wrapped around the fittings to prevent movement under compression loads. The support transfers the force of the load into the composite structure, ensuring that the force is absorbed effectively. In one embodiment, the support structure consists of a composite fiber tow made from high tensile strength fibers, which stiffens as the matrix material cures, securing the fitting in place.
