Abstract
Research conducted under the Primary Adhesively Bonded Structure Technology (PABST) program proved that adhesive bonded structures are far more tolerant of quite large flaws than had previously been believed. The PABST fuselage was made on development tooling rather than on production tooling which could have been refined after manufacturing began. Consequently, every panel was accepted for the structure and most of the flaws were left unrepaired, to be monitored during the testing. Because the PABST fuselage was not a flawless structure, the success of the test program was of even greater significance than it would have been for some perfect laboratory test coupon. The bond flaws simply did not grow, which gives great confidence in the reliability of adhesively bonded structures. Even the slow-cycle testing under extreme environments and loads did not damage the bonds in test coupons.
