NATIONAL ADVISORY COMMITTEE FOR AERONAUTICS LANGLEY FIELD VA LANGLEY AERONAUTICAL LABORATORY
A number of plastic materials have been proposed for structural use in aircraft. Material properties of these plastics must be established, however, before their use in aircraft structures can be put on a sound basis. Reference 1 presented the results of material-property tests of a plastic-bonded material of glass cloth and canvas and suggested a type of fabrication of plastic-bonded glass cloth which it was hoped might prove superior to the type used in the tests of reference 1. Results are presented herein of tensile and compressive tests of two types of plastic-bonded glass cloth, including a specimen fabricated as suggested in reference 1. The material for these tests was furnished by the Swedlow Aeroplastics Corporation, Glendale, Calif.
