Effect of adhesive type on peel strength of sandwich structures

Abstract

This research paper deals with an investigation of the mechanical properties of sandwich structures consisting of High Pressure Laminate facing layers (HPL) and various types of cores that are produced by vacuum bagging technology. These materials are connected with different adhesive layers and quality of connection to individual materials is evaluated. Moreover, prepared sandwich structures are tested in three-point bend. Based on the results, suitable combinations of individual materials are proposed for sandwich structures with regard to the quality of the adhesive bonding.
