“…Several computational studies were also seen in literature where the authors used different commercial FE software for analysing the effect of hole-size on the strength of composite laminates. One such work is that of Babu and Ali 35 which studied the effects of hole-size as well as material parameters such as the difference in fibre orientation and ply stacking. The composite laminate with a large diameter hole is found to be weaker compared to the ones with smaller diameter holes, irrespective of change in material parameters – fibre orientation or ply stacking orders.…”

Composite panels are widely used as structural members due to their high strength-to-weight ratio. In order to reduce further weight, cutouts or notches are introduced in these members. These cutouts also serve utility requirements such as man-holes for purpose of service as well as for passing electric or fuel lines. An aircraft wing rib is a typical example of such a composite panel. Even while composites with holes or cutouts provide great savings in weight compared to metallic structures, the presence of holes itself leads to strength reduction. The reduction in strength is due to the concentration of stress around the vicinity of the hole while the structure is under loading. Different-sized and shaped holes/cut-outs are used in composites structural members, which may serve for different purposes. They, in turn, introduce their own versions of stress concentrations effects in such members leading to weakening of the structure. The stress concentration effect in fibre composites also depends on other factors like fibre orientation, fibre material, matrix material, etc. Loading can also influence stress concentration. This review pursues vast research done in this area and attempts to compare and summarise the diverse findings for designers to obtain a comprehensive concept on stress concentration factor as an effective tool for composite structure design.

The main goal of this work is to understand the mechanical behaviour of composites to compression loads. A unidirectional (UD) fabric of E-glass fiber is the most common reinforcement in composite structural applications which exhibits excellent strength, modulus, resistance to water degradation and corrosive environments, durability, good and a quantitative and qualitative analysis is conducted on this model and the results are validated. An experimental test sample made of the E- Glass/Epoxy-resin composite is subjected to uniaxial compression test. The experimental results are validated with the multiscale mechanical model built. The FEA (Finite Element Analysis) is being utilized and the results obtained are validated through experimental approach. With such validated numerical model, application in micro wind turbine blade would result in faster prototype development. Keywords: Compressive strength, Composite material, Micro wind turbine, E-Glass fiber, FEA, Orthotropic Material, Numerical methods, Macrostructure, Microstructure.

One of the most important requirement from the materials is to provide more strength at the expense of less weight. E-glass fiber is the material which satisfy this requirement. E-glass fiber has various applications in fields such as aerospace, automobile, marine, p iping industries etc., that's make it is most versatile material of today's industries. In the present research work, attempt is made to fabricate the E-glass/epoxy composites at three different laminate orientations: 0º/0º/0º/0º/0º, 0º/45º/0º/-45º/0º and 0º/90º/0/90º/0º. Fabricated E-glass/epoxy composite specimens were tested for tensile strength, flexural strength and the experimental results had been validated through ANSYS software.
