Performance requirements: CAI vs. OHC

John Russell, who manages nonautoclave research programs for the Air Force Research Laboratory (AFRL, Wright-Patterson AFB, Ohio), recently threw down the gauntlet at the Fall SAMPE conference in Salt Lake City, Utah: “Give us a 25 percent improvement in notch properties with no microcracking in high-modulus fibers.” While OOA prepreg suppliers can’t do much about fiber microcracking, Advanced Composites Group (ACG, Tulsa, Okla.)  already has announced that its XMTM47 material will be commercial by next year, designed for 120°C/248°F service with the increased notched performance requested.
