Reinforcements
ω Carbon: Fibres are available in high strength, intermediate modulus, high modulus, and ultra high modulus grades. These fibres are mostly used in high strength, high stiffness applications, where benefit from weight saving outweighs the additional material cost.
ω Glass: Most commonly used is E-glass with S-glass being lesser used but higher strength alternatives. Glass is much denser than carbon and has lower strength and stiffness values.
ω Aramid: More commonly known as Twaron® or Kevlar®. Aramid is a low density fibre normally applied to areas or in components where there is a likelihood of impact. Aramid has the ability to absorb and dissipate energy, while also exhibiting excellent abrasion resistance properties.
ω Polyethylene: Better known as Dyneema® or Spectra®, Polyethylene has similar energy absorption characteristics to Aramid fibres, but is a much lighter, although more expensive fibre than Aramid. Polyethylene has little or no compressive strength and begins to shrink and lose its properties at a relatively low temperature (100°C/212°F).
ω Hybrids: All the above fibres can be mixed or hybridised, yielding property combinations not normally available with the individual fibres.
