I believe CF is laid into wet resin (mixed with a catalyst) just like fiberglass. There's still room for bubbles and voids. If the part is cast molded the process is different - in resin casting you try to use a vacuum table and/or possibly vibrate the solution to push trapped air out. Injection molding uses forced liquid pressurized into metal molds. They all have the same issues with occasional voids and trapped air. The ideal situation involves a super clean injection or fill, where both the solution and mold are in vacuum so that there is no possibility of trapped air. However this is very expensive and only used in very large scale manufacturing.

Due to the small numbers and demand in the VX market, about the best you get is either parts produced for another model which can be used or converted, or small, private manufacturors like Ron who casts/injects to order. Most fiberglass workers will also throw a CF part together for you. Most of the time and cost is in the mold making process. After the mold is made, the cost difference between CF, Kevlar or fiberglass is relatively small. The second part of the equation is the laber cost. CF is much cheaper done in asia due to the cheaper laber cost, and lack of good quality, safety and environmental controls. It's actually mujch cheaper to have CF done in asia and pay for shipping, than to produce the same part in the US.
