Abstract : This document is the final program report describing work performed by the Plastic Products and Resins Department of E. I. du Pont de Nemours and Company, Inc. for the National Aeronautics and Space Administration, Langley Research Center under Contract NAS1-14620. The objective of this program was to conduct research and development aimed at developing NR-150B2 polyimide resin into an adhesive for bonding high temperature graphite/polymer matrix composites. The adhesive was to be designed to have the durability for 125-500 hours at 589 K (600 deg F) in air and to have a significant improvement in processibility not previously obtained with high temperature aromatic condensation polyimide adhesives. jg p.13
