Written by GovTribe AI ·

The document is a detailed specification sheet for Advanced Composite Training Panels used in the Supplemental Advanced Composite Repair course. The specification defines precise manufacturing requirements for a composite panel measuring 18" x 18" with a 1" thick core, including:

  1. Exterior skin: 8 plies of quasi-isotropic unidirectional graphite epoxy tape (Hexcel T2C190-12-F263-2 or equivalent), with a balanced ply orientation. 2. Core: Fiberglass/Phenolic honeycomb, 3/16-4.0, 1" thick with continuous height and no splices. 3. Interior skin: 4 plies of Kevlar 49 Aramid prepreg (Cytec MXM-7880-/285 or equivalent) in a crowfoot cross ply lay-up. 4. Bonding between skins and core will use film adhesive equivalent to BMS5-154. The specification mandates wrinkle-free surfaces with no seams or butted joints, and includes precise dimensional tolerances of +/- 0.125 inches.
