多軸化平打組物複合材料の機械的継手における破壊と強度

Braided fabrics are useful as one of the techniques in realizing the concept of near-net shape in the reinforcement configuration of composite materials. When structural members are connected with other members, the mechanically fastened joint is well known as one of the simplest method. It has been confirmed in our previous paper that braided flat bar with a braided hole in which the fibers continuously orient, has high joint performance with small joint geometry. The effect of middle-end-fibers which are one of the braiding techniques is discussed in this paper. It is proved that performance of mechanically fastened joints with braiding structure containing middle-end-fibers is superior to no middle-end-fibers. Moreover, the effect of the continuous fibers at the sides of the flat braid is also discussed. It is clear that these continuous fibers are effective to raise joint strength.
