摘要：

Experimental investigations on adhesion between two polymeric materials were conducted using two component tensile test specimens obtained by overmolding process. Influence of overmolding process parameters on the adhesion strength was investigated. More the influence of testing speed was investigated. A HDPE J2200 polymeric and an LDPE B21/2 were used in the experiment as the substrate and respectively as the overmold. The interface adhesion has been modified by changing either the processing parameters or the roughness of the substrate surface at the two polymeric materials interface on the 2C specimens. In terms of adhesion strength the melt temperature process parameter was the most important factor. The combination of higher temperatures produced an increase in the adhesion toughness that was the result of a change in the mode of fracture at the interface.
