| Abstract: |
| The paper aims to study the bending behavior of unidirectional laminates reinforced with epoxy carbon fiber (CFRP) for aviation at low temperature. Test methods included changing the head radius, L/h ratio and whether there was plastic film liner between the head and the sample. The flexural properties of different test methods at low temperature -50 ℃ were studied. At low temperature, different test methods had different effects on the flexural properties of carbon fiber reinforced resin matrix composites.The stress concentration in the pressure head position on the upper surface of the specimen was significantly reduced when the plastic film liner was used; the change of flexural property was the lowest in low temperature environment at this moment. When the radius of the head decreased, the low-temperature environment had the most significant influence on the flexural property of the specimen. To measure temperature effect the performance of the sample, it is recommended to choose plastic film-free liner of small radius with L/h=32:1. |
