Continuous glass fiber composite is 60% by volume E-Glass Fibers and 40% epoxy resin Fiber Modulus of Elasticity = 75 Gpa Resin Modulus = 3.5 Gpa Tensile Strength Fiber = 2.5 Pga Tensile Strength Resin = 65 Mpa Note : Stresses parallel to fibers is iso-strain loading. Stresses perpendicular to fibers is iso-stress loading (a) Sketch thc compositc undcr iso-scrain loading and compute che modulus of elasticity. (b) For thc iso-scrain loading conditions in (a), compute the tensile strength ofthe composite. (c) For the iso-strain loading conditions in (a), compute the rraction ofload carrier by the fibers. (d) Sketch the composite under iso-stress loading and compute the modulus of elasticity ofthc compositc. (e) Compa re the modulus of elasticities for the composite under iso-strain and isostres loading.
