Determination of Mechanical Properties and Failure Pressure in Composite Cylinders

In this study, mechanical properties of cylindrical composite specimens were measured experimentally. Composite cylinders oriented at 0 degrees C and 90 degrees were manufactured by using the hand lay -up technique. The cylinders were loaded axially for measuring the axial tensile strength and compressive strengths. Some specimens were attached to a torsion machine for measuring shear strength and shear modulus. Thus, a close and true measuring was performed in the cylindrical specimens. A finite element solution was performed in closed ended composite cylinders under internal pressure and thermal loading. Thermal stresses occur at low and high temperatures with respect to the room temperature. For a true or close solution in composite cylinders, mechanical properties should be determined in cylindrical composite specimens
