An abrasive blasting process using plastic beads has been used to strip paint from USAF aircraft surfaces and component parts. The mechanical effects of Plastic Media Blasting PMB were studied on quasi-isentropic and uni-directional graphiteepoxy substrates. Effects of hand sanding were also investigated. After one paint and strip cycle, the effects of PMB were found to be minimal the mechanical properties varied within property limits of unstripped control samples. Using the primer as a flag to control stripping depth within the primer and resin rich gel coat is recommended to maintain mechanical properties.
