The table below gives physical properties for three types of fibers used to reinforce polymer resins to make PMC materials.

FIBER TYPE>>	CARBON	ARAMID	E-GLASS
Modulus of Elasticity- MSI	33	18	10.5
Tensile Strength- KSI	580	400	500
Specific Modulus of Elasticity- MSI	18.3	12.5	4.1
Specific Tensile Strength- KSI	322	278	197
Specific Gravity- g/cc	1.8	1.44	2.54
Relative Cost	High	Moderate	Low

MSI = million lb/in²

KSI = thousand lb/in²

Compare these fibers as the reinforcing material in PMC materials. In what types of applications might you chose each of them, keeping in mind stiffness, strength, density and cost factors? A thorough discussion is expected.
