Is there a benefit to adding biax cloth, to the laminate of a gluelam style

beam that will reinforce a weight bearing deck. There are to be 5 beams total, 8ft long, 1.5 in wide and made up up 6, 1/4 in thick strips, spaced 15 inches apart to support the flybridge deck. would adding a 0/90 biax , or 0 uni, intralayer, add any strength to the beam? Epoxy will be used for the lamination, and in turn the beams will be laminated to the underside, laid into a bed of epoxy and 1700 45/45 biax, and tabbed over with the same, 2 layers at 6 in and 4 inch tabs.

Currently strips are wetted out and clamped to a form, cut to the curve required. when dry they will then be glued up, using the form and clamps to hold them until set.

 

A layer or two of fabric will not add any serious amount of strength or stiffness to a laminate like this. The wood stack will be pretty stiff as you've described. Some unidi, top and bottom can help, but you'll need more than a layer or two to offer much more than a waterproof sheathing.

 

Thank you! As always you are most helpful. Happy Holidays.
