Carbon composite cylinders were fabricated using woven fabric composite sheets, and a mechanical device was designed and fabricated to apply internal pressure loading to the composite cylinders. This device can be used with a uniaxial testing machine without any fluid to generate internal pressure loading. Experimental tests were conducted for the composite cylinders to determine the failure loading using the device. Then, a multiscale modeling technique was utilized to predict the failure strength which was determined using the failure criterion based on the stresses and strains at the constituent material level such as fibers and matrix materials. Both numerical and experimental results agreed well. The subsequent studies to be conducted are physical tests and multiscale modeling and simulations to design carbon composite cylinders for extreme loading such as cases and containers for high explosives.
