About this file
This document is a detailed specification sheet for manufacturing advanced composite training panels for the ASM Supplemental Advanced Composite Repair course. The panels are precisely defined with specific material requirements: an exterior skin of 8 plies using unidirectional graphite epoxy tape (Hexcel T2C190-12-F263-2), a 3/16-4.0, 1-inch thick fiberglass/phenolic honeycomb core, and an interior skin of 4 Kevlar 49 Aramid prepreg plies (Cytec MXM-7880-/285). The panels measure 18" x 18" with a 1" thick core, and require specific layup orientations, transition angles, and bonding using film adhesive. Critical manufacturing specifications include maintaining wrinkle-free surfaces with no seams or butted joints, and adhering to +/- 0.125 dimensional tolerances for overall width and length.
