The crushing behavior of carbon/epoxy and glass/epoxy tubes haviing core material with concrete and honeycomb

In this thesis study, glass/epoxy composite square tubes with three different cell size (25 mm, 50 mm, 100 mm), three different cell height (30 mm, 60 mm, 120 mm) and two different fibre orientation ([- 45°/+ 45°]4 and [0°/90°]4) and carbon/epoxy composite square tubes with the same cell size and height and three different orientation ([-45°/+45°]4, [-60°/+60°]4 and [0°/90°]4) have been carried out manufacturing using the Hand Lay up Method. For produced composite tubes, core materials (fillers) aluminum honeycomb (honeycomb) and C25 class ready-mix concrete were used. The aim of the thesis study is to determine the effects of experimental parameters such as specimen size, fiber material type, orientation angle and core material on the axial compression behaviour of composite square tubes. The experiments was carried out using 250 kN load capacity Shimadzu brand universal testing machine at room temperature. After experiments, deformation shapes of composite square tubes was interpreted by figures. Also, the effects of the structural and strength properties of the core materials on the compression behavior of the specimens are investigated. For all parameters, the obtained results were compared in itself and with each other. Composite tubes with different specimen sizes and material types have produced using different fill types in ways that can be used for many purposes, can be characterized by the properties of the physical, chemical, mechanical, can increase the resistance of composite structures and can be brought optimal application performance of these structures, can be seen.
