Abstract
This paper presents the preliminary research of peel test of the adhesive bonding for materials using on parts of seating for public transport vehicles. Researches are focused on cooperation with the industry and their validity is conditioned by the need to automate the process of adhesive coat application. For the purpose of the experiment, two of the three materials composing the seat were selected: polyamide PA6 and polyurethane foam. Tensile strength tests were performed on polyurethane foam treated as the weakest component. At the further stage of the work, two adhesives were selected to for bond strength test. The first one was the adhesive used in the production of seats, the second one was selected on the basis of literature review. In both cases, adhesive was applied by spraying. Thus the bond strength was tested with the peel test as per EN 28510. The type of failure was also determined and the results are compared. Based on the obtained results, specific conclusions have been drawn to guide further research.
Abstract. This paper presents preliminary research of peel test of the adhesive bonding for materials using on parts of seating for public transport vehicles. Researches are focused on cooperation with the industry and their validity is conditioned by the need to automate the process of applying the adhesive coating. For the purpose of the experiment, two of the three materials included in the seat were selected They were made of polyamide PA6 and polyurethane foam. Tensile strength tests were performed on polyurethane foam treated as the weakest component. At the further stage of the work, two glues were selected to carry out a joint strength test. The first was the glue used in the production of seats, the second selected on the basis of literature recommendations. In both cases, the adhesive was applied by spraying. As a result, the strength of the peel connection was tested in accordance with the recommendations of the PN EN 28510 standard. The type of damage was also determined and the results were compared. Based on the results obtained, specific conclusions were made to guide further research
