Patent number: 11268639Abstract: A composite connector assembly includes first and second tubular members, each constructed from fibre-reinforced polymer and each comprising at least one layer of axial or helical fibre and each comprising an end portion with a clamping surface and an overclamp. The overclamp is arranged to at least partially enclose the end portions of the first and second tubular members and to apply a clamping force to the clamping surfaces so as to connect and hold the first and second tubular members together. In each end portion, the at least one layer of axial or helical fibre is diverted radially outwards. Each end portion may have a fibre redirecting member formed underneath the axial or helical fibre which serves to divert the axial or helical fibre radially outwards.Type: GrantFiled: June 11, 2019Date of Patent: March 8, 2022Assignee: CROMPTON TECHNOLOGY GROUP LIMITEDInventor: Will Pollitt

Publication number: 20210404511Abstract: A filament wound composite fibre reinforced polymer shaft comprising helical wound fibres, the shaft having at least one hole perpendicular to an axis of the shaft; wherein fibre paths of the helical wound fibres divert around the hole. The hole can be used as an attachment point to connect the shaft to other parts, e.g. by means of a pin passed directly through the hole. The amount of metal used in this type of connection can be significantly reduced compared to using metal end fittings, thus greatly reducing cost and weight of the whole system. Fibres are diverted around the hole rather than the hole being cut through the fibres which would reduce the strength of the shaft as a whole. By diverting the fibres around the hole, the fibres retain their load bearing properties and the strength of the shaft is maintained even in the presence of the hole.Type: ApplicationFiled: September 9, 2021Publication date: December 30, 2021Inventors: Will Pollitt, Andrew Wragg
