Composites versus Steel There is a lot to consider: Mechanical properties of composites are not a simple sum of its components • Incredible variation in material choice • Properties depend on the way the composite is made • Properties can change over time or upon use -> monitoring and repair • Properties other than mechanical/water or corrosion resistance. • Not a lot of standardisation yet. • Positive example, ACMA has succeeded in getting pultruded composites accepted in the building code.

of key
Both have their place and in some occasions there is good potential for better structural performance when they are combined. Each case is different, but if your problem falls in the following category, you might be able solve it with composites. Huidige constructie duur vanwege hoge onderhoudskosten
