MATERIAL - ADHESIVES - FMS-0015 (SHELL 422J OR HEXCEL HP-422) AND FMS-0016 (PLASTILOCK 620-626) JP-4 FUEL IN SANDWICH PANELS - EFFECTS OF
Abstract
Sandwich panels were fabricated in the laboratory using FMS-0015 (skin-to-core) and FMS-0016 (metal-to-metal) adhesives, glass reinforced plastic honeycomb core, 7075T-6 aluminum slugs and 2024T-86 aluminum skins and evaluated before, after and during a five year exposure period to outdoor weather. The following tests were used to evaluate the effect of exposure : 260 F core shear and shear modulus of rigidity, 260 F edgewise compression, 260 F accelerated column-beam creep, R. T. simple beam, R. T. lap shear strength and 260 F flatwise tension. In addition, standard half inch overlap shear specimens bonded with FMS-0015 and FMS-0016 adhesives and 2024T-3 skins were evaluated by immersion in JP-4 fuel at 140 F and tested at R. T. and 260 F at intervals up through a five year immersion period. Results obtained on the FMS-0015 and FMS-0016 adhesive bonded 4FTW244-3 panels indicate that neither exposure to outdoor weathering nor direct contact with JP-4 fuel results in significant reduction of panel strength up through a five year exposure period. Likewise no deleterious effects were observed when FMS-0015 and FMS-0016 adhesive bonded lap shear specimens were immersed in JP-4 fuel at 140 F up through a five year period.
