0.1: A composite strip made of unidirectionally glass fibers reinforced
polyamide has a mass of 2.25 kg and a rectangular cross section of 3.5 cm * 2.5
cm, and a length of 1.25 m. The glass fibers have a density of 2.6 g/cm' and a
diameter of 15 um and packed in a square array in an epoxy matrix. The
polyamide matrix has a density of 1.2 g/cm'. Assume there are no voids in the
rod
1. Density of the composite
2. Volume and mass fractions of the glass fiber and the epoxy matrix.
3. Volume and mass of the glass fiber and the epoxy matrix.
4. Find the fiber-to-fiber spacing between the centers of the fibers.
