Popis:	Composite cylinders made of a polymer matrix such as epoxy reinforced with glass or carbon fibers possess extremely high strength. Proper modeling of FRP composite cylinder is very essential for many applications. FRP composite cylinders are commonly used in the aerospace, automotive, marine and construction industries. The present work is to study the variation of stressesat the top end, middle and bottom end portions of a composite cylinder by varying the diameter to thickness ratio(S) and fiber angle (θ).The four layered angle ply (θ/-θ/-θ/θ) composite cylinder is considered forthe present work and behavior of each portion (Top end, middle and Bottom end) is studied.For the present work composite cylinder is modeled in ANSYS and analysis was carried out using numerical software. It isfound thatthe increment of stress takes place linearly with respect to D/t ratio due to reduction in thickness of the layer.The critical fiber angle is 450 to 600 as it offers high resistance against axial and circumferential deformation in middle and end portions.
