Experimental Optimization of Process Parameters for Tape Wound Composite Cylindrical Shells by using Taguchi Method

Ehthesham Uddin Qureshi, Md Musthak

Abstract


The purpose of this paper is to design and construct laminated composite cylindrical shells.  Tape wound layup method is implemented for the preparation of composite laminated shells by E-glass fiber mat and Epoxy resin as adhesive. The shells were made by considering two parameters p1-diameter of mandrel and parameter p2- stacking sequence. As per the L9 orthogonal array the required diameter and stacking sequence was arranged. The composite shells were fabricated by winding the mats on circular mandrel made up of PVC. These shells after drying up were removed from the mandrel, and buckling test and radial tensile test were conducted. The results were analyzed by Mean response, S/N ratio of both tests. And concluded that when the diameter of mandrel is small, buckling strength and Radial tensile strengths were more. And when the diameter increases the buckling strength and radial tensile strength both were decreased. And when hoop layers and helical layers were separately wounded i.e., 90/90/90 and 45/45/45 the buckling strength is less as compared to combination of Hoop and Helical layers. Whereas the radial tensile strength is more for all the layers are Hoop i.e, 90/90/90. Confirmation test was carried out on optimized process parameters. Confirmation test shows the maximum strengths for both buckling test ang Radial tensile test.
