The Effect of Different Tread Profiles on Pullout Strength of Glass Fiber Reinforced Polymer Composite Materials
Journal Title: Cumhuriyet Science journal - Year 2018, Vol 39, Issue 2
Abstract
Recently, the usage of polymer composite materials has been increased significantly. Glass fiber reinforced polymer (GFRP) composite materials are preferred for different areas such as aviation, railway, energy, defense and so on due to their high thermal and tensile strength. The most common methods for joining composite machine parts are bolts and rivets, etc. In this study, Pullout tests were performed with metric, knuckle, buttress, trapezoid and square profile screws to determine the effect of different screw threads on the pullout force. The bolts were taken to have a diameter of 16 mm and feed of 2 mm. In addition, a finite element model was created for determining the von-Mises equivalent stresses and total deformation. The metric thread profile gave the best results both in FEA and in experimental studies. The numerical and experimental results were in a good agreement could be concluded.
