g. Resin Injection For Edge Delamination Repa-
ir. The following describes a positive pressure resin
injection repair process for edge delaminations on
solid laminates. This process only works where the
damaged area is clearly deined and where airlow
out of the panel edge is possible. The procedure
requires positive airlow through the delaminated area.
A clamping device is typically used for pressure dur-
ing cure; the resin being injected can be illed with
