CST Composites: B14 Carbon Fibre Spars

CST supplies a complete range of carbon tubing for masts, spreaders and wings for the B14 class. Our 50 series masts are made using intermediate modulus carbon fibre and have been developed with the leading class sailors to offer the optimum bend characteristics and light weight.

The 50 series mast is also the current world champion spar can be purchased as either a rigged section, or a bare tube set.

Working closely with the B14 association, CST has also developed new carbon fibre wings replacing the existing aluminium variety. These are available as cut to length tubes ready for assembly or as a complete wing kit including moulded carbon joints and acetal fittings.

Please refer to the drawing below for details or our rigging guide for assembly instructions.

Note: For application of a carbon mast collar see document below:

Procedure:

Required Items

Masking tape

Sand Paper - 80 or 120 grit wet or dry

Epoxy resin

Micro fibre powder (glue powder) or pre-prepared epoxy glue mix

Acetone solvent

Preparation

Measure off the collar position on the mast. Measuring from the base of the carbon mast (not the heel), top of the collar should be at 295mm and the bottom at 215mm. Wrap masking tape above or below these points respectively.

Sand the region with 80 or 120 grit paper to remove the shine and provide a scratched surface for good bonding. Similarly sand the inside of the collar. If using dry paper care should be taken to avoid breathing in the carbon dust - wear a dust mask.

If wet paper was used dry the mast and collar.

Wipe the mast and collar with acetone on a clean rag.

Gluing

Remove the heel plug fastenings and see if the collar fits over the heel plug, if not remove the heel plug as well.

Remove the bottom masking tape to allow the collar to be slid into position.

Mix the epoxy resin (approximately 50g) and add glue fibre until the mix is stiff (like porridge) and doesn't drip off your stirrer.

Apply the glue to the mast and a very small amount to the collar (just wet the surface).

Slide the collar into position, ensuring some glue remains underneath; remove excess glue.

Check the collar is in the right position (top at 295mm from the base)

Remove masking tape. Clean off excess glue from the mast and collar with acetone on a rag.

Allow glue to set. Hold the collar in position with a small amount of masking tape if it is likely to move while curing.
