This document specifies a method for determining the lap-shear strength of the adhesive joint between carbon fibre-reinforced plastics (CFRPs) and metal adherends, using a standard specimen loaded in tension and under specified conditions of preparation, conditioning and testing. This method is intended for assessing the suitability of adhesives to be used for bonding a carbon fibre reinforced plastic (CFRPs) to a metal.st edition 2021-01 Composites and reinforcements fibres？—？Carbon？fibre？reinforced？ plastics(CFRPs)？and？metal？assemblies？ —？Determination？of？the？tensile？lap- shear？strength Composites et fibres de renfort — Assemblages de plastiques renforcés de fibres de carbone (CFRP) et de métal — Détermination de la résistance au cisaillement en traction Reference number ISO 22841:2021(E) ？ ISO 2021 ISO 22841:
