STUDY ON THE PERFORMANCE OF THE MID-TEMPERATURE CURED ADHESIVE FILM USEDFOR BONDING REPAIRING OF CIRRUS SR20 COMPOSITES

Abstract

Abstract: The differences between the curing process, mechanical properties and temperature of J-12 medium-temperature adhesive film were compared with those of AF-163-2M which was suggested to use in bonding repair of Cirrus SR20 composites. It was found that those two adhesive films have good curing rate between 120 ℃ and 130 ℃, and both of them could maintain good mechanical properties at 150 ℃ and meet the maintenance needs of Cirrus SR20 composites. The single lap shear tensile strength of cured J-12 adhesive film and AF-163-2M film were 30.1 MPa and 27.4 MPa at room temperature, respectively. The shear strength of cured J-12 film is better than that of cured AF-163-2M film. To sum up, the comprehensive performances of J-12 adhesive film are similar to those of AF-163-2M adhesive film, which could be used as an alternative product used in the Cirrus SR20 composites bonding repairing.

Key words: mid-temperature cured adhesive film, tensile shearing, curing process, heat resistance
