A solid CFRP tension membedesigned to link any two parts of a bridge superstructure. CL Solid CFRP Bridge Cable is driven by stiffness and break load demands - whilst both variables are treated independently. The inherent non-corrosive nature of carbon is further enhanced with a ceramic coating to increase resistance to chafe, impact and vandalism. Stiffness demands drive the selection of the applicable raw carbon fibre and matrix material, whilst break load demands drive the fitting size and form.

The CL Solid CFRP Bridge Cable is produced from pre-impregnated tapes and titanium fittings. Raw carbon fibres are impregnated with the optimum matrix material using our in-house, automated prepreg machine. This process ensures that the carbon fibre filaments are aligned perfectly along the load path - driving exacting stiffness. In addition, the prepreg tapes are produced to the correct width to correspond with the titanium termination, meaning there are no slit tapes along the entire length. Custom laminate plans are engineered for each cable, defining the number of loops, start and ending points of the tapes. The prepreg tapes are wound around the titanium thimbles in accordance to the laminate plan before being consolidated into a circular form on an automated winding machine. After consolidation, the cable is put under a predetermined load and held under tension whilst being ‘cured’ into a solid CFRP tension ready for shipping and installation.

Key Benefits:

  • Superior fatigue properties; reduced stiffness, consistent load distribution

  • Superior durability and corrosion resistance in harsh exposure environments

  • Weight saving; lightweight cable and reduced demand on support infrastructure

  • Significant reduction in cost of ownership; install logistics & maintenance cost

  • Competitively priced to inferior steel alternatives; less material required
