Hi, I broke my drone propeller blade made of cfrp. So i want to memic the same blade. The challenging part is to maintain the same weight and dimensions of the original propeller blade..
 I am using prepreg so that there will no confusion fibre resin ratio (for weight problem). I need to know about mould prepration because the blade has twist and pitch and also about lay up the prepreg  because the blade has various dimensions from trailing edge to leading edge.  so help me out in making my propeller blade made of cfrp.
