Abstract

The variation of Modulus Ec as a function of percentage of broken fiber for long aligned fiber composite subjected to longitudinal loading for constant vf content of 22%. It is observed that as ratio of broken to total fibers decreases Modulus decreases with linearly. Usually as broken fiber increases, the effective reinforcement decrease this reduces contribution of reinforcement in a linear manner. The loss in Modulus increases as percentage of broken fiber increase because reduction factor in fiber contribution Rs is function of β, fraction of broken fiber (ρv), aspect ratio (L/d), maximum shear strength (τmax) which gives less effect at low fraction of broken fiber and therefore the variation of 0-0.3 for fraction of broken fiber cause opposite zone for packages and model, therefore overall loss is obtained is more in case of packages. The comparative results of theoretical Models and FEA packages predicted values of Modulus respectively as a function of percentage of broken fiber for long aligned fiber composite subjected to longitudinal loading with experimental result.
