Zusammenfassung: | PURPOSE:To prevent ply separation from occurring even when considerable load is applied by a structure wherein the direct mounting part of a joint is joined to a tube by applying adhesive over the whole surface of the part and, in addition, the direct mounting part is fastened by bands together with the tube so as to be joined into an integral body. CONSTITUTION:The direct mounting part 2b of a fiber reinforced plastic tee- joint 2 is joined onto the surface of a fiber reinforced plastic tube 1 by applying thermosetting adhesive 3 over the whole surface of the part and, in addition, the direct mounting part 2b is fastened by fiber reinforced plastic bands 4 together with the tube 1 so as to be joined into an integral body. When loads are applied in the directions indicated with the arrows (a) and (b), a force is especially given in such a direction as to separate the direct mounting part 2b from the tube 1. However, as the direct mounting part 2b is given a strength larger than that of ply separation especially by the action of the bands 4, the critical tensile strengths in the directions (a) and (b) are turned to be increased by the amounts given by the action of the bands. |
