Abstract : The test program developed for the basic prepreg materials used in process development work and fabrication of the National Transonic Facility fan blade is presented. The basic prepreg materials and the design laminate are characterized at 89 K (-300 deg F), RT (room temperature), and 366 K (200 deg F). A discussion of the characterization tests, test equipment, and test data is presented. Material test results in the warp direction are given for tensile, compressive, fatigue (tension-tension), interlaminar shear and thermal expansion.
