SMART COMPOSITES FIBRES

SOME OF THE SMART COMPOSITES FIBRES ARE:

Carbon fibres are a type of material.

Fibres of Aramid (meta and para)

Fibres of glass (E-glass and S-glass)

CARBON FIBRE:

Carbon fibre is a composite material that is most commonly found in race cars and high-end supercars, but it is slowly making its way into more and more vehicles, as with all sophisticated technologies. Despite its high cost and high-tech applications, carbon fibre is a rather simple material to work with. Carbon fibre’s high cost is mitigated by its incredible strength and lightweight qualities. It’s also highly stiff, and body stiffness contributes significantly to effective handling, particularly at high speeds.

Some production supercars employ a carbon fibre monocoque, a structure that relies on the external skin for support rather than the traditional internal frame. Carbon fibre is also employed in body panels and other locations where exceptional rigidity and lightness are desired. Because of their similar manufacturing processes, carbon fibre and fibreglass are sometimes used together. An example of this is the Corvette ZO6, which has a carbon fibre front end and a fibreglass rear end. Carbon fibre, on the other hand, is significantly more durable and lighter than fibreglass. Carbon fibre is used in a variety of high-performance vehicles, including sports cars, superbikes, pedal bikes (where it is used to make frames), and powerboats. It is also frequently used in the tuning and customising industry, where attractive woven panels are left unpainted to’show off’ the material. The most expensive reinforcing fibres are carbon fibres. Weaved mats cost around 500 DKK per kilogramme. 2000-5000 MPa tensile strength.

Carbon fibre has numerous weight and performance advantages, but it is hampered by costly manufacture, maintenance, and recycling methods. The beauty of carbon fibre is that it can be produced in such a way that its directional performance (in terms of responsiveness to applied force) may be tweaked to get the best outcomes in almost any situation. While a material like steel will function well when subjected to forces in specific ways or from specific directions, it will nonetheless have flaws. More regions of vulnerability can be removed thanks to the ability to arrange fibres to meet the specific stresses influencing a component.

Carbon fibres are classified according to modulus, tensile strength, and final heat treatment temperature. Temperature exposures in the carbonization process range from 10000 C to 20000 C, with each level of exposure resulting in a distinct attribute for the fibre. For instance, high-modulus types are processed at 20000 C, high-strength types at 15000 C, and low-modulus and low-strength types at 10000 C. The most common carbon fibres are polyacrylonitrile (PAN) and pitch-based, and they’re well-known for their composite reinforcing and heat-resistant applications.

GLASS FIBRE:

Glass fibres are formed mostly of silicon oxide with a few additional oxides thrown in for good measure. Glass fibres are known for their excellent strength, temperature and corrosion resistance, as well as their low cost. E-glass and S-glass are the two primary forms of glass fibres. The first is the most common, and its name comes from its excellent electrical qualities. The second variety (S-glass) is extremely strong, stiff, and temperature resistant. Many industries, including as the automotive and marine industries, as well as sports equipment, use it as reinforcing materials. They are made by a spinning process in which molten glass is sucked out through a nozzle at hundreds of metres per minute. Glass fibres are inexpensive. Their braided mats cost around 15 DKK per kilogramme.

Because of their high surface area to weight ratio, glass fibres are valuable. The expanded surface area, on the other hand, makes them considerably more vulnerable to chemical attack. Glass fibre blocks provide good thermal insulation by trapping air within them, with a thermal conductivity of the order of 0.05 W/(mK).

Glass strength is often measured and reported for “virgin” or “pristine” fibers—those that have just been created. Because thinner fibres are more ductile, the freshest, thinnest fibres are the strongest. The toughness of the surface decreases as it is scratched. Glass has an anamorphous structure, which means its properties are the same both along and across the fibre. Humidity has a significant impact on tensile strength. Moisture is easily absorbed, causing microscopic cracks and surface flaws to worsen, as well as lowering tenacity.

Glass, in contrast to carbon fibre, may elongate further before breaking. The filament diameter and the bending diameter of the filament have a relationship. The viscosity of molten glass is critical for successful manufacturing. The viscosity of the glass should be low during drawing (pulling the glass to minimise fibre circumference). The fibre will break if it is too high during the drawing process. If it is too low, though, the glass will form droplets instead of pulling out into fibre.

ARAMID FIBRE:

Aramid fibres are noted for their high toughness and penetrating resistance. Aramid fibres are utilised when great impenetrability is required, such as bulletproof jackets, bike tyres, aeroplane wings, and sports equipment, due to their hardness.Because of their high water absorption, high cost, and complicated post-processing, these fibres are not as widely used as glass or carbon fibres. PPTA is used to make them. PPTA creates liquid crystals when immersed in a strong acid at -50 C. At 200 degrees Celsius, the liquid is drawn through a nozzle, where the acid evaporates and the crystals are orientated. Finally, the fibres are stretched at 500 degrees Celsius. Fibres with a hefty price tag. Weaved mats cost around 400 DKK per kilogramme. Tensile strength is around 3,600 MPa. The characteristics of aramid fibres.

Aramid fibre is a synthetic organic polymer (an aromatic polyamide) manufactured by spinning a solid fibre from a liquid chemical mixture. The brilliant yellow filaments produced have a variety of characteristics, but they all have high strength and low density, resulting in extremely high specific strength. All grades are very impact resistant, and lower modulus grades are commonly employed in ballistic applications.

Experience in boat rigging opens up a world of options for using Aramid Rigging instead of typical steel wire. In steel wire solutions, our endless-winding technique for end fittings substitutes the old, less lasting cone fittings.

Cables can be up to 50% less in diameter, making them significantly lighter!
