Abstract:

Little data is currently available concerning the properties of thin graphiteepoxy laminates supported by low density foam cores. To help fill this information gap a testing program has been initiated at Massachusetts Institute of Technology. The testing method, including preparation of test specimens, is outlined and the results of the first tests of zero to 90 degree laminates are presented. Analysis of the test results is limited to calculation of the Normal Distribution parameters for the zero degree elastic moduli and the Weibull Distribution parameters for the zero degree compressive strength. Methods of failure are documented with photographs and explanatory text. Author
