The specific weight of composites varies between 1.5 and 2.0 compared to 2.7 to 7.8 for aluminium and steel.
Typical GRP lambda values are 1, compared to 50 for steel and 237 for aluminium, which results in excellent insulation properties.
Double curved shapes are easily produced in composite materials at almost no extra cost. For production of limited series the relatively low moulding costs are an additional benefit.
By combining functions such as strength and insulation in one product, a composite solution is often more cost effective than the sum of traditional solutions.
