    Dear my friends,
    I have some questions about fibreglass boat construction as follow:

    2) Can we use 1 layer Mat + 30 layer (Woven roving) + 1 layer Mat + Polyester or Epoxy resin, to reache the required thickness, for example?

    1) What is the best fber configuration in lamination of hull thickness (combination of Mat and Woven rowing fibre) to have best bending and impact strength?


    Best Regards

    Ahmad

    This will not be pretty.

    I think you will need to give a lot more detail before anyone can help you.

    Dear lesburn1,
    Thank you for reply. For more detail, I can ask my question with more detail as follow. In my experience in fiberglass boat building, normaly in hand lay-up method, we use different types of fiber to obtain require thickness (and strength), for example using
    1 layer gelcoat+1 layer Mat fiber+ 2 or 3 layers woven roving (or other type)+1 layer Mat+2 or 3 layers woven roving (or other type)+ . . . + Polyester or Epoxy resin= Requier thickness

    My question is very clear.
    - Can we use 1 layer Mat + 30 layer (Woven roving) + 1 layer Mat + Polyester or Epoxy resin, to obtain the required thickness?

    I think that this detail will sufficient. I am looking forward for your reply.

    Best Wish

    I've always separated layers of cloth or woven roving with a layer of mat. But I also used vinyl ester instead of polyester or epoxy, too.

    WR is normally separated by CSM to allow composite infill bonding between layers.

    ...and yes, try VE resin instead of cheap polys as stated above.
