M40X HIGH TENSILE MODULUS Revolutionary Material |  Innovative Design M40X represents a major advance in carbon fiber technology. TORAY Industries pushed both fiber strength and tensile modulus to the extreme and applied technology to improve fiber orientation by closely controlling the graphite crystal structure in a nano order. The result is a revolutionary material that offers a 30% improvement in tensile strength over conventional carbon fiber. M40X eliminates the "boardy" feel through the use of proprietary nano technology and nanoalloy used in the prepreg matrix resin. This novel combination significantly improves shaft feel and performance.
