An epoxy matrix composite containing both HS (such as T-300) carbon fiber and E-glass fiber is to be formulated such that the cost/ kg is to be equal $ 8.00/ kg. It is desired to keep the total fiber volume fractionequal to 60 %. What are the required mass fractions of the carbon fiber, glass fiber and epoxy resin?
Use the following values:
Fiber Density (kg/m3) Cost ($/kg)
HS Carbon fiber 1770 $12.00
E-glass fiber 2540 $4.00
Epoxy resin 1250 $4.00
