Graphite-Reinforced Polycyanate Composites for Space and Missile Applications
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.
