Many researchers have investigated the means for enhancing the strength of the bonded joint of composite material. One of the topics is changing the surface geometry (e.g. wavy, taper, fillet) of the composite to improve the tensile strength and decreasing stress concentration of the bonded area. In this research, a method capable of improving the tensile strength of the adhesively bonded single-lap joint is introduced. The enhanced material was embedded into the glass fiber in the Seemann Composite Resin Infused Molding Process (SCRIMP) and formed a symmetry wrinkled surface composite material. The composite single-lap joint specimens were fabricated by following the ASTM D5868 01 standard and subjected to the tensile test to compare the strength of the conventional single-lap joint and the improved wrinkled surfaced single-lap joint. The test results have suggested that the wrinkled interface formed by the embedded material could successfully improve the strength. By embedding different materials, the improved rate would vary from 30% to 40%. Moreover, this research, which the common composite material fabrication process, SCRIMP, is applied to make wrinkled surface without a special mold is easier to promote to the industry. ? 2017 International Committee on Composite Materials.
