Abstract: Plastic-metal-hybrids are becoming more widely used for their high lightweight construction potential. In the field of hybrid composites, research has been developing rapidly for many years. The structural strength is a priority in research, so that measures of mechanical grouting of the metal insert surface lead to better traction results. Another benefit would be an impermeable joint zone. Therefore, the joint strength had been tested before and after alkaline-cleansing. The present paper proves the effects of alkaline-cleaned and untreated, laser-textured metal surfaces on the joint strength of plastic-metal-hybrids. The assessment showed a significant effect of the cleansing on the failure mechanism. In addition, the joint strength of all hybrid specimens was determined up to 15 MPa. The results of the examination also show a joint strength above the strength of the selected polymer material.
Keywords: Alkaline-cleansing, hybrid injection molding, joint strength, laser-texture, plastic-metal-hybrid.
