Table 2 presents the numerical data of static strength Su and its mean Su, while Table 3 presents fatigue life data. These data were systematically obtained as described above and are expected to be used for the reference or comparison data for conventional CF/BMI composite materials and new CF/BMI materials recently developed for low-cost and out-ofautoclave manufacturing such as those produced by a VaRTM (Vacuum assisted Resin Transfer Molding) method.
