| Abstract: |
| Objective To obtain the aging characteristics of carbon fiber reinforced nylon composites in both high and low temperature test conditions by analyzing its variation regularities of the mechanics properties under different test conditions. Methods High-temperature and low-temperature experiments were conducted to the carbon fiber reinforced Nylon composites with tensile and notched impact specimens and their tensile strength and notched impact properties were periodically tested. The change regularities of their mechanics properties were analyzed under different test conditions and then the aging characteristics of that kind of material was summarized. Results The appearance of material was not damaged under the test conditions. The impact strength showed the tendency of rising at the earlier stage and lowering at the latter stage. The tensile strength reduced a little bit at the earlier stage and then enhanced gradually. Conclusion Carbon fiber reinforced nylon composites had no visible characteristics of appearance aging in both high and low temperature tests. The mechanics property of the material presented the tendency of relatively slow thermal aging after 16 days of high-temperature test. |
