Glass fibre reinforced plastics are a lot more cost-efficient than carbon or aramid fibres but at the same time of high quality.

Glass fibres are the material most commonly used in fibre plastic composites, because processing it is especially uncomplicated, and it is explicitly suited for applications with a high level of mechanic stress. GRP is a popular material due to its outstanding material characteristics such as its exceptional strength, stability, and corrosion resistance, with a remarkably light weight at the same time.
