Graphlite Carbon Rod by Jim Marske

Whether your spars are constructed of fiberglass or carbon rovings you must take a serious look at this new miracle structural material. It's more than six times stronger than 2024-T3 aluminum, twice as stiff and nearly half it's weight. Compare this remarkable premanufactured carbon rod with wet layup carbon roving, it's nearly 3-1/2 times stronger in tension and 5-1/2 times as strong in ...

Carbon Spars - Home of World Beating Performance

The Black Art Of Carbon Spar Production. The use of advanced composites has rapidly developed over the past few years and especially in the production of Dinghy Racing spars during recent seasons. Many Classes have either allowed a change to Carbon Spars or are reviewing the possibility of change. A mast is used to hang the sails on and to control the leading (luff) edge of the sail for shape ...

Masts — GMT Composites

GMT’s first two carbon spars made in 1990 are still sailing today. We have many more examples including Defiant, a Hinckley 70 that went through a complete refit and our mast went back in. And we can't forget the custom Bill Lee 70' Merlin; She made a comeback winning the Transpac in 2017 using the mast we built for her in 2005. Bottom line, GMT spars last! Is a carbon mast hard to maintain ...

Lightning strikes and Carbon spars - Sailing Anarchy ...

17/09/2005  If a carbon spar is hit by lightning, x-ray is of no value since carbon is transparent to x-rays. The only way to inspect hidden damage is by tapping the same way a surveyor taps a hull, only it's much more difficult since the sound will change at patching, tapering, reinforcing, etc. Chances are that if you're hit, kiss it goodby. Any reputable carbon spar builder will offer a lightning rod ...

Wing Spar Modification - The BD-5 Web Site

The thermal expansion difference between the metal spar and the graphite can cause high stresses on the bond line over that length. The shorter the distance the less stress. Obviously you do not want the carbon fiber sock to be in the region where the metal wing spar slides over the center section. Obviously when you put the inflated tube down through the center of the sock, you need the ...

Sky Shark Tubes

Sky Shark wrapped carbon tubes are renowned around the world for their use in building kites and hobby related products. Sky Shark produces both tapered and straight wrapped tubes. What is a wrapped carbon tube? The method for making a wrapped carbon tube involves the use of wrapping a resin pre-impregnated fiber cloth around a mandrel. The diameter and the length of the mandrel determines the ...

Steen Aero Lab - Aircraft Products - Laminated Wing Spars

Laminated material is at least 25% stronger than natural (solid) wood.** See note below Laminated spar sections remain dead straight to provide for a more accurate structure, free of warps or bows.; Using a laminated spar incurs no weight penalty over a solid spar.; Laminated spars are easy to work with - it's no different than solid spars.; Laminated spars use thinner sections of wood, which ...

11/11/2014  Carbon spars start out painted or clear coated when new. the clear coat needs to be redone ever 5 years and paint may last a little longer but mot much. Thats $5K ever five years. Leave an aluminum mast with the paint peeling in the sun for more then a year and it is still good to go, do that to a Carbon mast and it is Carbon dust. When aluminum cracks you stop dill it and it is good for a ...

Graphite is used in epoxy coatings to make hulls and ...

Galvanic corrosion has been observed in fitting used on carbon fibre masts and spars. Generally a graphite epoxy coating is too resistant to electricity to be useful but not resistant enough to ignore. For this reason if you decide to coat your centreboards, hulls or any other structure in a boat to reduce friction, any fitting or pivot should not touch the graphite mixture and be isolated ...

Carbon fiber spars SailNet Community

15/11/2007  Because carbon fiber spars are so light for their strength and so can have higher safety factors, initially, they actually tend to be much stronger and less likely to fail than the aluminum spars that they replace. Carbon fiber spars have had an excellent safety record. Its not that carbon fiber spars are without some liabilities. They do take greater care in their fabrication, expecially in the methods used

Steen Aero Lab - Aircraft Products - Laminated Wing Spars

We are able to buy high-quality spar wood and finish-saw it ourselves, and are able to be very competitive on spar wood pricing both for solid and laminated materials. Laminated spar technology is not a new phenomenon; it was routine in the Golden Age of wooden aircraft design in the 1930's and 40's. The process requires more labor than solid spars, but since thinner sections are used, any

Graphite-epoxy Composite Design for Aircrcaft Wing Spar ...

To carry out progressive failure analyses of the various graphite-epoxy composite wing spar designs under bending moment, finite element analysis with ANSYS 14 Mechanical APDL software was employed to determine which spar design would best withstand the bending moment of 10,000Nm generated from the MATLAB MuPAD software. The investigation revealed that all the three designs of Low Modulus

Applications of Carbon fibers in thermoset matrices-

The spars were built on mandrels, producing five cells to give the spars, which were covered with dry carbon fiber reinforcement, placed in the mold and then covered with carbon fiber fabric to give a single piece structure. Carbon fiber braid was chosen as the ideal reinforcement for the spars since it could be precisely positioned and kept in place. Some spars had two layers of braid.
