Abstract
In this research, with the aim of investigating the effect of temperature on the performance of adhesive, riveted and composite glass/epoxy joints, the factors affecting this joint are studied. After checking the parameters, preparing the surface of the connection area using sandpaper on two levels using sandpaper with grain numbers of 220 and 400 and also controlling the thickness of the adhesive layer on two levels of 0.13 and 0.26 mm. The meter and the type of drill used to make holes on both surfaces were selected using a saw drill and a wood drill for rivet connection. The integration of selected parameters of two adhesive and riveted joints is considered in order to investigate the combined joint. In this regard, the experimental design using the Taguchi method has been carried out in the Minitab test design software. The purpose of conducting the experimental part of this research, as mentioned in the previous lines, is to obtain optimal joints according to the defined parameters and levels in order to set a standard and compare with the values obtained after performing the test on the mentioned joints under the effect of 80 It is the degree Celsius applied to the samples for four hours. In order to bring the results closer to the industrial conditions, we connected a number of adhesive, riveted and combined samples using the optimal levels of parameters defined for each of them, based on the zigzag arrangement of four rivets along the width of the area, which
