Carbon
|
NZ Spars & Rigging carbon Fibre masts and Booms are manufactured in house and in one Piece using female Moulds, Prepreg carbon, which are then autoclaved cured at up to 8 bar.
All the Local patching, reinforcing and stiffening as required is added during the Laminate stage and Co-Cured with the mast section resulting in a smooth Outside Finish of the mast section. Our autoclaves are electronic control steam heated. This gives us near perfect heat distribution and temperature ramping control which inturn insures the sections are straight and accurate. One of the advantages of having alloy moulds is as the temperature increases the mould expands and increases in length. The carbon fibre in the mast section however does not expand so is tensioned straight in the process improving the stiffness of the finished product. The advantage over the Mandrel wrapping system which requires the material to be wrapped around a mandrel resulting in the required extra reinforcing must be applied to the outside surface which produces an unfair section which must be faired increasing the weight. This also means the shape of the mast is inconsistent. The advantage over building the masts in two halves and bonding and mechanically fastening the mast into one piece along the transverse lap is a lighter section, no filling, fairing or secondary bonding, and a smooth internal finish to the mast, no glue, rivets or screws the full length of the mast to chafe halyards etc. Contact us today to Discuss the Vision for your Project and I’m sure the team here can help. |
