Title: Manfred Meinbreckse: Innovator in Carbon Fiber Technology

Introduction

Manfred Meinbreckse is a notable inventor based in Friedrichsdorf, Germany. He has made significant contributions to the field of carbon fiber technology, holding a total of 3 patents. His innovative approaches have advanced the production methods of carbon fibers, making them more efficient and effective.

Latest Patents

Meinbreckse's latest patents include a novel spinning method for producing carbon fibers from high boiling bituminous substances. This process involves spinning a purified and polymerized concentrated carbon fiber precursor into fibers, which are then oxidized and carbonized. A key improvement in this method is the addition of 2 to 10% by weight of a solvent, which is insoluble or only slightly soluble under normal conditions. This mixture is processed under hypercritical conditions for at least 10 minutes, preventing the formation of gas or solid inclusions in the fiber.

Another significant patent is a method for producing a carbon fiber precursor from coal tar pitch. This method involves extracting coal tar pitch at elevated temperatures and pressures using a mixture of a supercritical gas and an entraining agent. The process yields a solution free of quinoline-insoluble components, which is then treated to convert a substantial portion into pitch containing mesophase. The resulting isotropic pitch has a high mesophase content and is suitable for producing high-quality carbon fibers.
