Title: The Innovations of Robert L Kolek

Introduction

Robert L Kolek is a notable inventor based in Cupertino, CA (US). He has made significant contributions to the field of engineering, particularly in the development of advanced materials and methods for composite structures. With a total of 3 patents to his name, his work has had a lasting impact on various applications.

Latest Patents

One of Kolek's latest patents is for a low modulus damping film. This film is designed to accommodate high shear strain in a rigidly supported epoxy impregnated Nb.sub.3 Sn superconducting coil (SCC). In generator applications, the SCC experiences a combined load due to differential thermal contraction, magnetic, and centrifugal forces. These strains can lead to coil fracture and degradation of the field and current-carrying properties. By using a low modulus material at the interface between the SCC and support structure, the shear strain can be reduced or distributed to an acceptable level, ensuring no degradation in current-carrying properties. Suitable damping or interface films include polyethylene terephthalate Mylar (DuPont Chemical) and polycarbonate Makrofol KG (Mobay Chemical). An adhesive such as polyurethane Bostik 7070 is used to affix the film to the winding surface.

Another significant patent involves a method of forming a joint between a tubular composite and a metal ring. This method includes steps for creating a composite to metal joint between a metal ring and a tubular composite formed from crossing helical windings of high-strength fibers. The process involves winding the fiber on a mandrel at a helical angle equal to or greater than the slip angle of the fiber. The metal ring is designed with a hyperboloid surface and isotensoidal surfaces of revolution, allowing the helical fibers to form straight lines without bridging, thus creating an interference fit between the composite and the metal ring.
