Hi guys,
Has anyone ever heard of using a polyster fabric/cloth in place of fiberglass cloth when covering
sheeted areas
Better test your material and adhesive first. DACRON polyester is used as peel ply when laying up glass. That is, you use the DACRON on or partially in the lamination and then after the epoxy cures you peel or rip off the DACRON ply. Dacron doesn't stick to epoxy. It leaves a perfectly shaped but rough surface to which you can continue to bond without any further preparation.
For instance if you want to lap a glass ply along the leading edge of a wing and you're having a problem with the edge of the fabric not laying flat. You lay up a ply of dacron over the joint/lap. when the resin has cured, you peel off the dacron ply. It leaves the glass fabric perfectly flat on the underlying ply, the epoxy feathers perfectly evenly over the upper to lower ply leaving the joint invisible, and the surface is smooth enough to not require any shaping but rough enough to allow bonding without further preparation.
