In order to study the shear performance of the repair technique of lap-stitch,specimens were prepared using a vacuum-assisted molding process.The experimental results shown that the sample was in the deformation state with the shear strength test of ± 45 ° specimens,the plane shear strength was 105MPa.The fracture morphology was a broom style,the epoxy resin was completely pulled,and a 45 °grain direction can be seen in the specimen.The interlaminar shear strength was 15.6MPa with the short-beam test method,and a pure shear failure mode was occurred in the center position.
