TAKE YOUR ADVANTAGE
Cost effectiveness and freedom of geometry
Composites can be tailored to your purpose through fibre orientation and material combination. The correct design of the properties results in a very cost effective product. Due to the low life cycle costs, the cost advantage can be enormous. High, directional strength (anisotropy) enables structures and properties that cannot be achieved with conventional materials.
The superior material properties enable aesthetically pleasing designs, e.g. slim constructions and seamless facades, which cannot be achieved with conventional materials. The surfaces can be very stylish and good looking.
Fibre reinforced composites outperform most metals in strength in absolute numbers as well as in weight to strength ratio.
Fiber-reinforced plastics are much lighter than metals yet can still achieve their rigidity. Experience shows that the use of composites can realise a weight saving of 20% to 400%. The specific weight of composites varies between 1.5 and 2.0 kg/L compared to 2.7 kg/L for aluminium and 7.8 for steel.
From stiffness to fexibility
With fiber composites, rigidity can be calculated and modified with the utmost precision from elastic to maximum rigidity. The stiffness to weight ratio of a high modulus carbon fibre construction is typically 5 times higher than steel or aluminium.
High resistance to fatigue
Fiber composites fatigue slowly and increase the life of highly stressed components and and can be defined in detail. The fatigue resistance of composites is much better than that of metals.
Steel structures typically require periodic maintenance such as conservation and paint systems to prevent corrosion. Composites are not susceptible to corrosion, resulting in lower Life-cycle costs.
Perfect for rude conditions: Composite materials are resistant to salt and seawater, most solvents, oil, acids, hydroxides, etc. Extremely high resistance to corrosion gives a long service life in even the most aggressive environments.
Limited thermal expansion
The expansions of composite materials can be designed up to the zero expansion, depending on the fibre used. Fiber composites expand must less than metals.
Up to ten times more effectively than metals.
Typical GRP lambda values are 1, compared to 50 for steel and 237 for aluminium, which results in excellent insulation properties.
Carbon fibre used in a polymer matrix can be designed that is thermally conductive in the fibre direction with thermally insulating transverse to the fibre direction.
High transparency to radar and excellent permeability to xrays.
Glassfibre reinforced composites have superiour non-magnetic properties.
