FIELD: machine building.
SUBSTANCE: invention relates to machine building and can be used in designs of gas and hydraulic filters and accumulators and all similar containers using shells from composite materials, as well as in aircraft and rocket equipment. Power shell 1 comprises docking face frame 2 with radial grooves 3 distributed in circumferential direction for the pins. From all layers 4 of composite material based on unidirectional and woven reinforcing material and polymer binder. Pins are made with smooth holes for pins 12 in form of two halves 5, 6 arranged with gap 7 between each other. Pins are made integral with annular beads 8, 9 and have inclined surfaces 10, 11 symmetrically located relative to axis of pin 12. On the side of inclined surfaces 10, 11 there are brackets 14 with central holes 15 for pins 12. Tails 16, 17 of brackets 14 come on inclined surfaces 10, 11 of pins and have inclined surfaces 18, 19 responding to them.
EFFECT: invention allows to increase joint unit strength and enlarge application of power shells from layered composite materials.
