    I am studying hull bottom thickness with the regulation of iso 12215 -5 C.1
    FRP laminate single skin

    i found out Pbm Base :45,2 kN / m2 ..?
    Pbm :33,36 kN / m2...?
    t1 : 5.2 mm
    1. question : Is this minimum 5.2 mm thickness of bottom (Chopped strand mat +viny lester +catalizer ) a CORRECT approach for a 7.5 m fiberglass boat?

    2. question : how many layers of chopped strand mat should i use for bottom ?

    450g (1.5 oz) Chopped Strand Matting +2.5 kg of Resin will “wet out” 1kg of Chopped Strand Matting
    Property Description
    Glass Type E
    Binder Type Emulsion
    Filament Diameter micron : 11
    Coupling Agent Silane
    Mat Density g/m² 450 & 600
