Solve the following problem:
The amount of fibers in a composite sample can be determined by a burn-out test. The burn-out eliminates all the resin and only the fibers remain. A composite sample plus its container weights 50.182 grams before burn-out and 49.448 grams after burn-out. The container weighs 47.650 grams.
Compute the fiber weight fraction WF and matrix weight fraction WM.
