            Mr. Neubert has 46+ years industrial experience, of which 45 has been directly associated in the advanced composite materials field.  He is expert in materials selection, structural analysis, design and fabrication technology of composites for the aircraft and spacecraft industries.  As an independent consultant during 1979 through 1992 and 2006 to present, his skills and experience are in constant demand.  He is nationally recognized for work using composites in dimensionally stable structures and microcracking effects resulting from extreme thermal environments.

            As a structural analyst, Mr. Neubert is highly proficient in performing detailed hand calculations and finite element analysis.  He is well versed in the use of NASTRAN, ANSYS and Strand 7 for static and dynamic solutions to complex problems.  He has developed and markets nationally, special purpose software packages used in composite analysis.

            As a Part 23 and 25 FAA Structures and Composites DER, Mr. Neubert has participated in the type and supplemental certification process, including transport aircraft seating, TCAS installations, composite aircraft develop­ment, and numerous general aviation modifications.  He has published extensively on the use of composite materials in custom built aircraft. 

            As an independent consultant, Mr. Neubert has assisted firms in the transportation, aerospace, and commercial industries to develop new products and bring them to the marketplace.  On long term assignments, Mr. Neubert typically resides on site with the host firm, while smaller assignments are usually performed on a FFP basis from the Anaheim Hills office.  References and additional information are available on request.
