For future battery-enclosure panels:

1. It is better to laminate from downwards-up

   • Reduces risk for dry-spots - the resin cannot just flow in-accordance to gravity

2. Depends on the scale of the part
   Perforate your core with 1/8” holes spaced around an inch apart

   • helps the resin flow-through adequately through both-sides

   • can use school’s CNC machine to program and cut-holes

3. Always perform a vacuum-drop test before starting infusions

4. Use breather if-possible to prevent the bag from being punctured

5. Always add lots of pleats (6” long) to your bag so that every-crevice is covered well with the tape

   • including at the tubing where the Enka sits

6. Instead of wrapping the chromate tape around the tubing, stuff the chromate inside, poke a small-hole for the resin to go-through, and then

Calculations for resin:

• general rule is to give core a buffer of 10%, and for all-else a buffer of 10%

• good to perform a gel-test with a small amount of resin to see how fast gelling occurs - record initial temperature, amount of time which has passed and amount of catalyst-used

  • learned that you can get-away with a lot less catalyst than you realized

Male versus Female Mold:

• Male molds are better for when you want the out-side of your part to look nice, for example for the aero you want the outside of the car to be the “A” side to decrease drag so you use a female-mold
