Abstract

The effect of strain rate on the mechanical response of T800/F3900, a strengthened epoxy carbon-fiber reinforced polymer, is studied by conducting compression and tensile tests at different strain rates. Low strain rate tests (0.001 s−1 and 1 s−1) are done using a hydraulic frame and high strain rate tests (300 s−1–600 s−1) are done with the SHB technique. Digital Image Correlation is used in all tests to obtain full-field strain measurements. Tension tests have been done on unidirectional laminates in the 90 ° direction. Compression tests have been done on unidirectional laminates in the 90 ° and through the thickness directions. No or small strain rate effect is observed between the low strain rate tests. The results from the high strain rate tests show significant strain rate effects.
