Development of engineering data on the mechanical and physical properties of advanced composites materials. Final technical report, 1 Jun 1971--30 Nov 1973

The program generated basic data on the effect of various environmental variables on the physical, thermal, and mechanical properties of selected resin matrix and metal matrix materials. The three resin matrix materials systems were Boron/Avco 5505, Modmor II Graphite/Narmco 5206 and Courtaulds HMS Graphite/Hercules 3002M systems. The two metal matrix materials systems were 6061 Aluminum/Boron and 6Al-4V - Titanium/BorSic Composites. The resin matrix systems were procured in the form of prepreg tapes and specimens were fabricated at IITRI materials laboratory. The metal matrix composites were fabricated by vendors in laminate form and supplied to IITRI for specimen fabrication and testing. The environments included steady state and cyclic thermal, thermo-humidity, and humidity conditioning.
