Units
Condition
- Condition
- autoclaved T300/Code 69 UD-prepreg multidirectional strip laminates with reproducible star-punch surface damage
- Temper
- not applicable
- Heat treatment
- Code 69 described as a 175 degC high-pressure, high-bleed system; detailed cure dwell/pressure not supplied
- Product form
- UD prepreg built into multidirectional Sample A and cross-ply Sample B strip laminates
- Thickness / diameter range
- 2.4 mm total laminate (A) and 1.7 mm total laminate (B); no ply thickness inferred
- Test direction
- strip longitudinal tensile loading; exact relation to every ply axis depends on stated layup
- Processing route
- autoclave-prepared T300/Code 69 UD-prepreg laminates
- Temperature range
- 20.0 ... 20.0 degC
- Notes
- NASA-TM-75351 identifies the exact carbon/epoxy system and documented laminate-strip test configurations, but does not tabulate absolute lamina modulus, strength, strain, thermal expansion, interlaminar shear, density, resin fraction or glass-transition temperature. Its strength and fatigue results are primarily normalized plots. PropLib imports no curve-digitized values, does not infer ply thickness from total laminate thickness, and does not convert the report's qualitative damage-strength discussion into a numerical property. The 175 degC description is a system/process reference, not a fully specified cure cycle or glass-transition temperature.
