I always use vacuum infusion technique to manufacture my CFP, but weight matters with me, and I want to limit resin uptake of balsa wood core material, so I was asking if I put the resin myself on the CF layer up and down the wood core material then put it in vacuum bagging, can this help me on decreasing the resin taken by balsa wood?
If not, please tell me how to decrease the balsa wood resin uptake.

I agree with what Fasta said about the trade-offs. Higher density foam is easiest but balsa is hard to beat for compression, shear or price! There are manufacturers of Balsa that make pre-sealed infusion balsa that soaks up half (or so) as much resin as standard balsa. Gurit Balsaflex, Corelite PC11 are examples.
