Design and Finite Element Analysis of E-glass Fiber Reinforced Epoxy Composite Air Bottle used in Missile System: Experimental Validation [ ]


The objective of this paper was to design the air bottle used in military system and to validate the design using finite element analysis. The load bearing capacity of the air bottle was 40 MPa. The air bottle was made of E-glass/epoxy composite. The hoop and helical winding layer thicknesses were, respectively, 3.6 3.013 mm. Matrix splitting was occurred along the fibers. The fibers were broken when the air bottle was tested at a pressure of 60 MPa.
