 It also indicates the CMBT particle density in the polymer matrix can be up to 95%.Phase 4 and Phase 5 testing reports used an epoxy/CMBT solution.More recent testing reports from March 2017 are showing samples with CMBT ratios of over 80% and in that same report EEStor mentions plans for near term samples with thickness of 70 microns with plans for greater levels of densification with near complete densification.
