Özet
This study presents the results of experimental research on the behavior and stretching of hollow
cylindrical epoxy tubes made of glass, carbon, and kevlar fibers subjected to axial compression load.
Hollow cylindrical tubes were fabricated by fiber winding method using glass, carbon, and kevlar fiberreinforced composite materials. In this study, hollow cylindrical composite tubes with constant outer (Ø17
millimeters), two different inner diameters (Ø12 and Ø13 millimeters; 2 ve 2,5 millimeters wall thickness),
and 80 millimeters in height. Experimental research was carried out for two dissimilar wall thicknesses
and four fiber orientation angles. The compressive strengths of all samples were investigated
experimentally by applying loads in the axial direction. Twenty-four configurations of composite
specimens were fabricated (three reinforcement materials, four winding angles, and two wall thicknesses)
to research the impact of axial compression stress. Experimental results revealed that polymer
reinforcement material, fiber winding angle, and wall thickness have a significant impact on the
compressive stress of cylindrical composite tubes as a result of applied load in the axial direction. The
conclusions show that the compressive stress of all reinforcement rises as the orientation angle and wall
thickness increase under an axial compression load, and the compressive stress reaches a maximum when
the orientation angle is 90° under an axial compression load. It was observed that the axial compressive
stress was highest in glass/epoxy samples with 217 MPa, followed by carbon/epoxy samples with 173
MPa and kevlar/epoxy samples with 145 MPa, respectively. The axial compressive stress of all samples
was highest at a 90° orientation angle and lowest at a 15° orientation angle. were found to have low values.
It was observed that the axial compressive stress value increased in all reinforcement materials as the wall
thickness increased.
