Abstract

The high-temperature-resistance property of the embedded co-cured damping composite is very important to its application in special environment. A new high-temperature-resistance ingredient of viscoelastic damping material is found through orthogonal experimental method to be co-cured with high-temperature-resistance composite preperg (T700/QY260). Damping material is dissolved in tetrahydrofuran to form viscoelastic material solution and then it is used to produce damping membrane on the composite preperg by brush coating process. After the composite preperg with damping membrane is laid according to the design requirement, the autoclave is employed to make the embedded co-cured high-temperature-resistance damping composite specimens. The interlaminar bonding force between the damping layer and composite is tested before and after high-temperature aging to study the high-temperature resistant performance of this embedded co-cured damping composite. The results show that the composite material has good high-temperature-resistance performance and it would provide a possibility for the wide application of embedded co-cured high-temperature-resistance damping composite.
