| Abstract: |
| Neutral salt fog spray of carbon fiber epoxy composite material was carried out to study the durability of the carbon fiber epoxy composite material in marine climate. The change mass, interlaminar shear strength and bending strength of the material after salt fog spray test was analyzed combined with heat aging mechanism. The results showed that with the test time increases, the moisture absorption of the material increases, mechanical strength decreases, and the material shows plastic characteristics; moisture absorption has significant influence on mechanical properties at primary phase; the interlaminar shear strength and bending strength decreased 10.3%, 9.8% respectively. |
