The following data were obtained in a resin burn-off test of an E-glass-polyester sample: Weight of an crucible = 10.1528g, Weight of crucible + sample before burn off = 10.5219g, Weight of crucible + sample after burn off = 10.3221g.

Calculate the fiber weight fraction, the fiber volume fraction, and the density of the composite sample. Assume Pf = 2.54g/ml, and Pm = 1.25g/ml. Do you expect the calculated value to be higher or lower than the actual value?
