Research Report RR:D30-1003
Four laboratories participated in the ruggedness testing portion of this investigation. The ASTM D3039 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 a 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 test by their facility.
