Fibreglass Lamination Plan

[alpamis34]

Hi All,
I am starting a new GRP boat project and after having done the preeliminary design,now it s time to kick off the building.My query is about the lamination of the fibreglass,I am thinking what kind of fibre I have to use while doing the lamination.How am I going to determine the kind of fibre for each layer? I know that I have to use strand matt and woven to reach the desired thickness.but how many layers with matt and how many with the woven.Also the density is another issue ,what densities do the layers have to be with?

Thanks in advance
