From my own research and a couple of posts on some surfboard construction sites (i didn't bookmark...sorry!) mat tends to soak up more resin and create a higher resin to glass ratio, thus creating excessive weight. In a discussion over flashchat with Loki he suggests laying up unidirectional at opposing 45 degree angles and testing the flex after each layer until you get it just the way you want it. Er...two layers at opposing 45's then one at 90 then if it's still flexy a 30 degree angle. this would do more for torsional stiffness (which was My issue) than longitudinal (nose to tail) but it would certainly add to the stiffness as well.
HOWEVER this longwinded suggestion is according to various sources and personal calculations without having yet gotten my board to that stage and thus have not applied these calculations to an actual product yet. The internet is full of people who have however. one strategy is to search forums dedicated to the construction of things other than skateboards but which still use composites. These sites often provide a different set of expertise and set of knowledge that can still be applicable to boardbuilding!
Hope that helped more than confused, Best of luck to you!

Fiberglass ? is this okay?
Linear Mode
