Compute the longitudinal modulus of elasticity (in GPa) for a continuous and aligned hybrid composite consisting of aramid and glass fibers in volume fractions of 0.22 and 0.30, respectively, within a polyester resin matrix, given the following data:
Modulus of Elasticity:
(GPa)
Glass fibers 72.5
Aramid fibers 131
Polyester 2.5

Respuesta :

Polyester 2.5? I would guess just so that the modulus of elasticity would have a higher volume?
