Composite Material Properties: M55J 954-3
RTD 72F A A-basis to RTD 72F A mean
Fiber-reinforced composite lamina (ply-level) mechanical properties from CMH-17 Rev G, MIL-HDBK-17, and authoritative datasheets. Covers carbon/epoxy, glass/epoxy, aramid/epoxy, PEEK thermoplastic, metal matrix composites (MMC), and ceramic matrix composites (CMC). Properties include elastic constants (E1, E2, G12, nu12), strengths (Xt, Xc, Yt, Yc, S), and physical properties across multiple test conditions (RTD, CTD, ETD, ETW) with mean and B-basis values.
