D3039_D3039M-Test Method for Tensile Properties of Polymer Matrix Composite Materials

Four laboratories participated in the ruggedness testing portion of this investigation. The ASTM D 3039 Tensile Test method was used to test four composite materials including a glass/epoxy uni-tape, carbon/toughened epoxy uni-tape, aramid/epoxy fabric and a glass/epoxy uni-tape which is believed to be strain rate sensitive. These materials were tested at a variety of different lay-ups and specimen configurations to accomplish the stated objectives. Laboratories were requested to provide failure strength, failure strain and chord modulus data for each of the specimens tested by their facility. The interlaboratory study portion of this investigation was conducted using the ASTM D3039 Tensile Test method on six composite materials in a variety of lay-up configurations. The materials tested included: IM-6/3501-6 uni-tape, glass/epoxy uni-tape, carbon/toughened epoxy fabric, Toray carbon/epoxy uni-tape, Toho carbon/epoxy uni-tape and glass/polypropylene unitape. An average of five replicates per test condition were tested by the participating laboratories. The number of participating test laboratories ranged from five to nine depending on the material type. Laboratories were requested to provide failure strength, failure strain, chord modulus and failure mode for each of the specimens tested at their facility. Laboratories were requested to provide failure strength, failure strain and chord modulus data for each of the specimens test by their facility.
