- Abstract
- Samples of Thornel 300 graphits-fiber/epoxy composites--one of tape construction (sx-3) and the other a combination weave and tape material (sx-4)--were tested as a means of decreasing weight and increasing strength of various aircraft components such as wings and rudders. Testing was aimed at assessing the ease with which graphite fibers must be release from these components during fires or explosions or both. The weave sample was one-fourth the thickness of the tape sample and lost its epoxy binder more quickly in burn tests, i.e., 29 percent in 1 min for sx-4 versus 2.7 precent in 1 min for sx-3.
