    Thanks for that, it demonstrates the point nicely.

    Not that it will stop someone coming along in another day/week/month claiming that GRP structures are superior in toughness to metal ones when it comes to boat hulls.....

    You can do a lot of things with GRP that is difficult to do with metals. Impact and abrasion resistance simply are not 2 of the superior features.

    So we can look forward to explosion formed steel canal craft by the banks of the Wey Navigation....;)

    There are other examples, like aluminium 20' containers which allow approx 1 tonne more internal load, yet are tough enough for commercial service.

    It is not about toughness but the hardness. Steel is high density material and with high density comes high modulus. Thus if you rub steel against FRP, the steel will win much like filing the edges of an FRP laminate with a steel file.

    Attached table shows steel has a higher modulus than FRP.
