| Abstract: |
| Objective To design environmental worthiness experiments of carbon fiber reinforced nylon composites at low temperature, analyze aging regularities and mechanics properties change in low temperature environment, and research the environmental worthiness of material at low temperature. Methods Impact strength of carbon fiber reinforced Nylon composites was taken as the primary character. Impact samples were test at -50 ℃. The impact strength was measured on schedule to analyze mechanical property and aging tendency in different experiment conditions. Results The carbon fiber reinforced Nylon composites became brittle and the impact strength fell 40% over at low temperature. But the composites material’s impact strength would recover to original, when the temperature rose to normal from low. Conclusion The shock resistance of carbon fiber reinforced nylon composites used at low temperature falls apparently and becomes brittle. But the material has good low temperature storage performance. In combination with the natural test result, it can be deemed that the material has good h environmental worthiness. |
