    Question about fiberglass panels (how much to use for a panel)

    I am beginning to experiment with fibreglass. First i am going to start with fabricating small pieces, pieces that have curved edges, etc, just to know what it is to work with fibreglass. How much fibreglass do i have to use to make a piece that can be used as a "panel" for a kitcar. What i want to say is, how thick does a panel have to be in order to have enough stiffness.

    Re: Question about fiberglass panels (how much to use for a panel)

    The necessary thickness will depend on where the panel is to be used. If it is structural and will have to support a load it will need to be thicker than if is just a covering panel. I usually shoot for about 3/16 thick for structural panels, cover panels can be thinner. Try and use only enough resin to wet the mat and cloth. More resin actually makes the final part weaker as resin has no real strength and is only a matrix to bind the fiberglass fibers together. More resin will also make the part heavier than necessary.
