| 摘要 |
An article comprises a superposed plurality of identical, disc-like laminae of fibre composite material and has a thickness which varies around the disc, being thickest at a number of first areas (56 - 60) circumferentially spaced apart around the disc. The thickness in the first areas contains all the laminae and the disc thickness tapers by stepwise reduction of the number of laminae in second areas (61, 64) on each side of each first area so that there are two second areas between two circumferentially adjacent first areas. The article may be divided into reinforcing elements (71 or 163) each containing a first area (55) and two adjacent second areas (61 and 72) or part of a first area (156) and one second area at the side of the first area and these elements may be used to reinforce the fixing portions (12) of a composite annular coupling disc (10) or link (166). |
