Abstract: The hot pressed laminate of glass fiber cloth/toughened phenolic resin was taken as the research object,the surface-surface bonding properties of the laminate were characterized by drum peeling strength, and the microstructure of the failure form of the adhesive surface was observed by electron microscope. Combined with the above tests, the effects of laying mode, testing direction, warp and weft density, forming parameters on the peeling strength of eight three flying satin laminate rollers are studied and the laws are found out. The results show that when the stripping surface is weft yarn surface,the drum peeling strength for which peeling surface long floating fiber are vertical and parallel to the loading direction is better than warp surface. The interlaminar adhesive property of 0° is the best, and the laying direction of non-stripping surface has no effect on the drum peeling strength. And the increase of theodolite density is helpful to improve the drum peeling strength. In a certain range of heating rate, reducing the heating rate is helpful to improve the peeling strength of the drum. And the time of pressure has no effect on the peeling of the interlaminar drum.
