Abstract : This report supplements the data and analyses provided in the previously released 'Composite Failure Analysis Handbook,' WL-TR-91-4032. It contains fractographic data from failed composite test specimens as well as case histories of failed composite structure. Fractographic data from statically loaded test specimens are presented for carbon/epoxy (AS4/3501-6), carbon/pseudothermoplastic (AS4/KIII), carbon/polyimide (AS4/PMR-15), carbon/thermoplastic (AS4/PEEK), carbon/bismaleimide (AS4/MR-54-4), and carbon and glass low temperature curing epoxy, (HTA 5131-12K/Rutapox L-20/SL and EC 9-756/K43/Rutapox L-20/SL) materials. Fractographic data are presented for translaminar and interlaminar, carbon/resin laminate fatigue specimens, as well as for several failure modes in composite skin, nomex honeycomb core specimens. Three failure investigations, including two composite honeycomb structures and one carbon/epoxy laminate structure, are also documented.
