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.
