| "plastic" and "resin" are interchangeable terms depending on where in the world you are. FRP (fiberglass reinforced plastic) and fiberglass are the same thing, i.e. the resin IS plastic, and the fiberglass reinforces the matrix, hense the name. "woven" just means they didn't use fiberglass flox or CSM, but actual cloth.
Technically speaking, there is no such thing as "dry vacuum woven plastic", or "dry vac bagging", or "dry carbon parts". Fiberglass thats dry is just fiberglass cloth, you need to add resin, which makes it "wet". Vacuum bagging can be done 2 ways, normally you'd use "pre-preg" or wet out the cloth, then place it in the vac bag to press out the air and excess resin, making a stronger part. Another way is placing the fiberglass and core if any in the bad dry, then using the vacuum (and gravity) to draw in the resin through a tube from a bucket. This is called resin infusion, and results in less excess resin production and waste, but harder to get right without doing lots of testing and experience. People who are not specialists in the field of composites call this "dry" because it's not "wet layup" (which do not use vac bagging), but just because it's not "wet" doesn't make it "dry".
Anyways, that hood is just a vac bagged fiberglass hood. Which is good.
