INSERT COATING AS A PRE-PROCESSING APPROACH FOR IMPROVEMENT OF ADHESIVE BONDING IN PLASTIC-METAL HYBRID STRUCTURES

摘要

Improvement of adhesive bonding between plastic and metal components by means of surface coating pretreatment has been investigated. Metal inserts have been coated with polymer-based film then overmolded with reinforced polyamide-6 in an injection molding process. Experimental work has included the characterization of the adhesive bonding strength and the influence of the coating film on the mechanical behavior. FE-Simulation has been conducted to analyze the local shear stresses. Aging influence has been evaluated using climate change test.
