Selden Phantom Carbon S2 High Modulus Mast

Selden Phantom Carbon Series 2 High Modulus Mast

The investment in a sophisticated carbon filament winding machine and autoclave enabled Selden to produce a new generation of carbon spars.

The following steps ensure that Seldin can manufacture the best performing and most consistent spars on the market:

In-house specialist design team

Seldin has the design expertise and software to create a mast to meet exacting performance requirements. During the design process the position and alignment of each fibre is precisely calculated so as to meet the required bend characteristics. This detailed design is then used to program and control the filament winding equipment. The combination of meticulous care, long experience, and exact specifications enable Selden to achieve optimum performance for minimum weight.

Computer controlled laminate lay-up

Carbon filaments are wound around a mandrel (male mould), under controlled tension, via a designated winding program supplied by the design team.

Filament winding, a computer-controlled process (CNC), guarantees consistent and accurate filament fibre orientation from spar to spar. Carbon filaments can be laid from 00 (uni-directional) to leave 890 (hoops) and at all angles between to produce a wide range of bend characteristic requirements. This accurate alignment of composite filaments is vital to the performance characteristics of a carbon spar. Fibres are laid under tension, which means that Selden can make the most efficient material choice and supply the lightest spars on the market. This process gives a Seldin spar a level of tube consistency unattainable via any other composite manufacturing technique. Hence, the mast you buy will perform as well for you as it will for a world champion sailor!

Use of pre-preg carbon

Only the highest grade pre-preg tows of T700 or TZ carbon fibre are used to give sailors the best stiffnessto-weight spar. This, in combination with the filament winding process, enables the highest fibre-to-resin content pre-preg to be used.

The aerospace grade pre-preg has a UV stabiliser in the resin system to give the spars a guaranteed long life, even in the sunniest of climates. More fibres and less resin, mean lighter, stiffer masts.

Autoclave cured

The consolidation of the material to form a ready-to assemble carbon tube is completed in Selden's in-house 20-metre long autoclave. The combination of heat and pressure to cure the resin and consolidate the pre-preg material ensures a strong and consistent final product.
