The following data were obtained in a resin burn-off test of an E-glass-polyester sample: Weight of an empty crucible = 10.1528 g Weight of crucible + sample before burn-off = 10.5219 g Weight of crucible + sample after burn-off =10.3221 g Calculate the fiber weight fraction, the fiber volume fraction, and the density of the composite sample. Assume Pr= 2.54 g/cm3 and Pm = 1.25 g/cm3. %3D The following data were obtained in a resin burn-off test of an E-glass-polyester sample: Weight of an empty crucible = 10.1528 g Weight of crucible + sample before burn-off = 10.5219 g Weight of crucible + sample after burn-off =10.3221 g Calculate the fiber weight fraction, the fiber volume fraction, and the density of the composite sample.
