The acid digestion test left 2.595 g of fiber from a composite specimen weighing 3.697 g. The composite specimen weighs 1.636 g in water. If the specific gravity of the fiber and matrix is 2.5 and 1.2, respectively, find the
1. Theoretical volume fraction of fiber and matrix
2. Theoretical density of composite
3. Experimental density
4. Weight fraction of fiber and matrix
5. Void fraction
