Step 7 Layup III Core

There are many type of core -- in fact, just about anything can be used as a core material. Even garden hose! We will be using a material called CoreMat.

CoreMat soaks up resin and expands a bit. When it has been fully impregnated with resin, it turns a deep yellow color. Too much manipulation when coated with resin will damage the mat (much like rubbing wet paper towels).

To apply this type of core. Simple drench the area you will apply the core to with resin. Stick on the core and work in more resin until it's completely soaked.

Some other types of Core:
1. Carboard
2. Honeycomb (of many types including paper, aluminum, etc.)
3. Steel or Aluminum (good for super strong mounting points)
4. Foam
5. K-mat (a scored foam with fiberglass back)
