Publication number: 20230383869Abstract: A composite tube comprising a region of greater diameter forming a bellow. The bellow has a first side and a second side spaced apart in the axial direction of the tube. Each side of the bellow comprises at least one hole and the at least one hole on the first side is offset in relation to the at least one hole on the second side. The holes in the bellow provide increased flexibility, thereby allowing a greater amount of bending or articulation in the shaft.

Patent number: 11193619Abstract: A fibre-reinforced polymer component is provided which comprises a main portion comprising fibre-reinforced polymer and at least one surface and at least one raised feature extending from said surface. The at least one raised feature consists of non-reinforced polymer and is shaped to incur visually perceptible damage when the component is subject to an impact with an energy above a predetermined impact energy threshold and to resist an impact with an energy below the predetermined impact energy threshold. The at least one raised feature thus provides a clear visual aid as to when a component has experienced an impact with an energy above the impact energy threshold. Because the raised feature consists of polymer without fibre reinforcement, it is more fragile than the fibre-reinforced polymer main portion 204 and thus reduces the energy at which impacts may be detected.Type: GrantFiled: May 29, 2019Date of Patent: December 7, 2021Assignee: CROMPTON TECHNOLOGY GROUP LIMITEDInventors: James William Bernard, Paul Daniel Liddel
