New Fasteners from Fulcrum Outperform Traditional Composites

04 March 2005

Fulcrum Composites Inc. has launched an innovative range of composite threaded products.

Fulcrum claim that the new products overcome many of the performance problems associated with existing composite threaded rod offering significantly higher strength and greater elongation to failure.

Typical applications include joints in composite structures in chemical plants, water treatment, air pollution control, radar and electronic towers, cryogenic equipment, marine, transportation and infrastructure.

The initial product range includes both English and Metric threaded rod in sizes from 1/2”-13UNC to 1”-8UNC and from M12-1.75 to M16-2.0 Fulcrum threaded rods can be readily thermoformed to produce high strength U bolts and hanging straps and produced to order in any required colour.

The threaded rod is produced in a newly developed process which combines sequential operations of thermoplastic pultrusion, extrusion, and moulding/forming to optimize tensile strength, thread strength and torque resistance. The patent pending process does not involve cutting the fibres as in existing processes used for thermoset threaded rod. As a result the threads are significantly stronger and have better chemical resistance as the fibre ends are no longer exposed to chemical attack.

The threaded rods will be showcased at JEC in Paris between 5 – 7 April.
