摘要：

A description is given of the stress and strain systems in adhesively-bonded joints; special attention is given to the new problems which arise when bonding advanced fibrous composites. The anisotropic properties of composites can give great strength in the fibre direction, but it must be remembered that the tensile strength transverse to the fibres is less than of the matrix. Finite element analysis is used to predict the stresses and strains. In the ultimate, 3-dimensional non-linear mechanics with anisotropic non-linear stress-strain properties must be used. Finally, when using the mechanics principles described here, improvements in actual joint strength of 3 to 5 times were obtained.
