Steps
- Plan 3 or more layup orientations to compare.
- Lay up fiberglass coupons with epoxy, wearing gloves and working with good ventilation.
- Let the coupons cure, then weigh and measure each one.
- Load-test each coupon to failure on the load cell rig.
- Calculate strength-to-weight for each layup.
- Chart the comparison and document the study for your portfolio.
What to photograph for your portfolio
