In order to substitute and recycle the existing automobile parts for GMT‐Sheet, researches on the effects of GMT‐Sheet on the establishment of precise joining strength, joining condition that are lap length of joining part, compression ratio, and closure speed must be carried out but until now, there is almost no case of systematic researches on joint of GMT‐Sheet. Therefore, as there are many obstacles in joining of GMT‐Sheet molding products or in production of stable molding products, the researches on these issues are required. Because of this, it is reality that GMT‐Sheet is only applied to parts of newly developed automobiles instead of substituting the existing automobile parts. In this study, materials with each different fiber content ratio and fiber orientation state were used in the study for decision of molding condition of GMT‐Sheet and the condition of lap joining. Clarify joining strength and lap joining efficiency during high temperature. Compression press lap joining molding of GMT‐Sheet and research data regarding to the lap length of joining part was presented. Thus, the purpose of this study is to contribute to the substitution of existing products as well as usage development in non‐automobile field and also to find out precise dynamic characteristics as designing data of structures.
