摘要：
A sealant made from a stoichiometric mixture of amine terminated butadiene-acrylonitrile copolymer and epoxide resin has been used to make single lap-joints in aluminium. These have been immersed in jet-fuel, water, antifreeze and an antifreeze-water mixture prior to testing. Strengths were much increased by pre-treating the metal by phosphoric acid anodization or with silane coupling agents. Joints were weakened in antifreeze but not in jet-fuel or antifreeze-water. In water weakening of joints with the silanes is accompanied by corrosion. Crown Copyright (C) 2000 Published by Elsevier Science Ltd. All rights reserved.
