Development of a field repair technique for mini-sandwich Kevlar/epoxy aircraft skin.
Cripps, David Bruce
MetadataShow full item record
An experimental analysis was performed on Kevlar/epoxy cloth "mini-sandwich" panels with cellular foam core. Three undamaged panels and twenty-three other panels with damage and repairs were subjected to static shear loading. Four parameters were varied in the types of repairs; hole size, hole plug filler material, patch material, and patch overlap distance. All twenty-six panels were tested to failure. A repair technique employing a cellular foam plug and fiberglass patches overlapping the original hole by 0.50 inches, symmetrically applied with structural adhesive, was found to be suitable for repair cf up to three inch diameter circular holes at field repair level. Additionally, postbuckling energy absorption was Qualitatively examined for undamaged panels and for hole sizes ranging from 1.00 to 5.00 inches diameter.
