Abstract
Some mechanical properties of electroplated ABS plastics were measured. It was found that its tensile strength conformed to a simple composite law; namely, the value of its tensile strength was equal to the sum of each value of the electroplated metal and the base, and there was no interaction between both materials.
S-N curves in fatigue tests were obtained for the plastics the etched one and the electroplated one When the fatigue limit was expressed in terms of the strain amplitude, the value of the electroplated plastics was much lower than that of the base. The above tendency also appeared in bending tests and the electroplated plastics were essentially “brittle”. The fatigue limit of the etched one, was decreased from that of unetched one.
Initiation and growth of cracks were observed during the fatigue tests and the behavior was varied according to the thickness of the film.
