Engineered laminate of Scotchply SP 381 Uni S29 111BW 33RC, stacked [+-45/90/+-45]:2s. Properties here are laminate-level effective values in the laminate's own axes — not the lamina constants, which live on the parent prepreg (Scotchply SP 381 Uni S29 111BW 33RC — S2-449/PR 381). From MIL-HDBK-17-2F Volume 2 (US Government work, public domain).
