Hi guys,
so ive been searching for a supplier for carbon and carbon kevlar fabrics for about a month now and i have finally found one who meets my specifications for the latter mentioned materials.

only problem is he only supplies fibreglass (which i need for mould making) in woven form. its really cheap in bulk so the price dofference doesnt bother me compared to chopped, but is it suitable for mould making? i think yes, but better safe than sorry

general rule of thumb is woven is 0.7-0.5x the UD strength (weave dependant) and CSM is about 0.3x then there is another reduction for fibre/resin ratio
