Producing an octagon shape with RI?

I have attached an image of the part I want to produce, the overall diameter of the exterior diameter is about 14 inches. The smaller holes have been designed out so it is a solid piece with the large hole in the centre. The part will be 10mm thick. I am using roving mat and a 3d core material. Would resin infusion work with this shape? I was planning on running spiral coil around half of the exterior circumference and drawing the vacuum from the opposite side. My concern is the resin will not penetrate the depth of the laminate, would it be better to laminate two halves and then bond them together? Any assistance would be greatly appreciated! B.

The better way to plumb your resin and vacuum lines would be to have the resin feed in the middle and the vacuum spiral around the outer circumference to infuse evenly from the middle.
