ABLATION SHIELD DEVELOPMENT TESTING SURFACE PREPARATION OF BERYLLIUM FOR ADHESIVE BONDING

摘要

Design studies conducted la an effort to reduce the weight of space vehicle component parts sad in order to extend the sissies capabilities of space vehicles have resulted la a proposed re-entry shield considerably lighter than those presently used. Such a shield, consisting of an ablation Mastery al bonded to a beryllium back up structure, has been proposed for the re-entry shielding of space vehicle. A four phase development program was initiated to determine the optimum materials and fabrication techniques required to fabricate the proposed re-entry shield. It was the purpose of this phase of. the development program to evaluate various methods of preparing beryllium surfaces for adhesive bonding.
