Composite Material Properties: AS4 3501-6
RTD ±602s LPT mean to RTW 75F W 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.
