Abstract:

LtCol Michael Obal of the BMDO Materials and Structures Office sponsored this workshop to promote communications among the participating groups and to identify technical issues and limitations associated with graphite- reinforced polycyanate composites. Some of the identified issues include a lack of standard materials and associated process specifications due to continuing changes in resin and prepeg formulations. Perhaps the most discussed issue was the lack of a statistical database, due, in part, to the changing formulations just mentioned. Development of a handbook via government coordination of existing information may be one way to provide data to designers and increase material acceptance. In addition, high resin contents in prepeg tapes a lack of appropriate protective coatings a need for structural bonding processes a need for additional, environment-related data, particularly effects on mechanical physical properties a need for joint tests and subsystem level tests of structural components and limited design tools and standards for using composites were discussed.
