A STUDY OF THE IMPACT STRENGTH OF EPOXY-RESIN BONDED ASSEMBLIES

ETUDE DE LA RESISTANCE AUX CHOCS D'ASSEMBLAGE COLLES PAR L'INTERMEDIAIRE D'UNE RESINE EPOXYDIQUE

A study was first made of the effect on the impact behaviour of materials bonded with epoxy-resin of the thickness of the bond, the chemical cleaning of components and the temperature. The experimental model used consists of A sheet of metal joined to two parallelopipeds of metal or mortar by means of a joint of adhesive material. The resistance to shear by impact of the adhesive bond of the assemblies is characterised by the energy at failure. Secondly, since the measurement of the failure behaviour does not permit the breakdown phenomena to be wholly understood, the maximum force developed at the point of impact on the plate was assessed by two methods of calculation, one based on the impulse diagram, the other depending on the "stress-strain" diagram. A knowledge of this force allows the permitted impact shear-stress in the resin film to be determined. In the third section the calculation of the maximum elastic energy absorbed during flexure of plates of different materials allowed A correlation to be made with the experimental results which describe the behaviour of the sheets during impact.
