Abstract The various methods which have been used to measure the joint strength of a glass‐polymer interface have been reviewed and the results compared. Conclusions have been made regarding the strength of polyester and epoxy joints and the role of the coupling agent in enhancing this strength. Bond strength methods discussed include the flat plate test as well as the single filament techniques. The stresses which exist at the interface in an actual comosite are calculated. The relation of the glass‐polymer joint strength to the final strength to the final strength of a glass reinforced plastic composite is dissussed. The interaction of the interface with an advancing crack is also considered.
