Multi-part assembly technology

Multi-part assembly technology, combined with the use of the Araldite system from Huntsman Advanced Materials, has been used in the construction of sports bicycle frames by Time Sport International.

Located in Charancieu, France, Time Sport specialises in the development and manufacture of bicycle frames and accessories. Its new high-performance model - the RXR - makes use of assembly technology that is based on high modulus carbon composite components. Each frame consists of three parts made in mould 'shells' using the Araldite epoxy system with carbon fibre. "This unique technology enables the mechanical features of every shell to be modified according to specific requirements thus providing each bicycle with unparalleled performance for its rider", says Huntsman's Karin Eisenblatter. The system used to produce the carbon components comprises Araldite LY 564 and Aradur 22962 which can be cured at temperatures of >100ºC. "This amine-cured laminate system has very low viscosity so is suitable for the latest injection moulding techniques used by Time Sport such as resin transfer moulding." It also has a long pot life (up to 150 minutes at 23ºC) and high reactivity; for example, curing for 15 minutes at 100ºC.
