Mr. Keith has been President of HK Composites, Inc. for seventeen years. He has developed several types of injection-molded connectors for use in concrete/insulation foam board sandwich wall construction. Performed structural analysis, selected materials, conducted qualification testing and wrote test reports. He has been granted over twenty patents in the U.S., Europe, Australia, Canada, Mexico, Japan and China. He provided the structural engineering for many concrete houses, buildings, and other structures.

From July 1990 to January 1993, he was a Regional Manager in Utah, of ESCM and Associates Inc, Athens, Georgia. He performed risk assessments, contaminant transport modeling, finite element analyses, seismic and structural analyses, and program management. Mr. Keith developed a patented remediation method for Toxaphene in soil and groundwater.

From May 1988 to July 1990, he was Director of Engineering, AeroTrans Corp. (formerly Winding Technologies Corp.) Springville, Utah. He managed design, manufacture, and installation of a five axis, dual carriage filament and tape-winding machine for General Dynamics. This included developing control software and electronics. He helped develop a robotics center, which can automatically machine, filament wind, or tape wind, using machine control commands generated directly from a CAD model. Other advanced composite projects he worked on included cryogenic tanks, aircraft waste tanks and air deflectors, I beams, and various electronic control and sensing systems.

Hercules Aerospace employed Mr. Keith for ten years. As Manager, 3D Composites Technology, he conducted programs to develop and characterize improved 3D (three-directionally reinforced) composites for a variety of applications including propulsion, reentry, space and aircraft structures, turbine engine components, and hypervelocity vehicles. He supervised a group of engineers in development and evaluation of improved resins, densification cycles, and in the optimization of chemical vapor deposition process parameters. He directed technical development, marketing, and prototype manufacturing activities for 3D and carbon carbon composites and other developing technologies including 3D woven thermoplastic composites, ceramics, biomaterials, and oxidation-protected carbon carbon.

As Supervisor, 3D Composites Programs and Applications, Mr. Keith coordinated carbon carbon needs and requirements of large propulsion programs and managed government technology programs and R&D projects. As Program/Technical Specialist/French Liaison, 3D Woven Structures, he assisted in the licensing of Aerospatiale 3D weaving technology and coordinated the technology transfer, including formation of initial specifications and technical requirements for weaving and densification processes and equipment. He evaluated 3D weaving technologies at three European companies including Brochier, Societe Europeenne de Propulsion, and Aerospatiale.

He was involved in several areas of rocket nozzle design, analysis, and fabrication. These areas include crack propagation in bond lines, ablation prediction, material properties synthesis of composite materials, thermal/structural analysis, process stress analysis of carbon-carbon exit cones, flex seal design and analysis, and filament wound nozzle design, analysis, and fabrication. He utilized sophisticated computer analysis methods, including finite element thermal, structural and flow analyses, to predict the behavior of various components and structures.

Mr. Keith designed five advanced technology nozzles for an AFRPL Contract (Evaluation of High Performance Propellants for Application to an ICBM Upper Stage). He was directly responsible for the analysis of the Pershing II nozzles and was the chief analyst on the Naval Surface Weapons Center’s Strategic Missile Materials Technology Program and Carbon Carbon Filament Wound Cone Program. He was the principal investigator for Hercules successful IR&D demonstration motor firing of its 3D carbon-carbon nozzle. He also provided nozzle design and analysis support to the Trident II and Peacekeeper programs.

Mr. Keith developed the Initial Flex seal Design computer program. He made modifications to other computer programs including: GASKET, ASTHMA, Hercules’ proprietary finite element program and DCAP (composite analysis program); and adapted the application of Hercules Initial Case Design program to filament wound exit cones. This work resulted in 7 approved Cost Improvement Recommendations. He is experienced in the development of finite difference computer codes. As a graduate research assistant, he developed a computer code to aid in the design and analysis of solar heated concrete buildings.
