Profile: Hardy Advanced Composites is a manufacturer of carbon fiber, and glass fiber tubes. We are an ISO 9001:2008 certified company. We manufacture composite tubes from carbon fiber, glass fiber, aramid fiber, or a mixture of materials. Every tube we make is constructed using a mandrel wrapping process, which allows the accurate placement and alignment of fibers to achieve a composite tube with the optimum balance of stiffness, strength, and weight for each application.
