A sheet of fiber reinforced plastic consists of E-glass chopped-strand mat (CSM) (30% mass fraction) in a
matrix of thermoset polyester. The glass fibers are randomly arranged in the plane of the sheet.
Estimate the in-plane tensile modulus of the sheet. (In CSM the fibers are sufficiently long (10 to 50mm )
that they may be considered to be continuous as far as elastic transfer is concerned).
