Abstract

Abstract: During last two decades the growth of composite materials was remarkable. The volume and number of applications of composite materials are rapidly growing and continuously conquering new market fields. The demand for these engineered materials varies from consumer goods to advanced niche applications, reflecting substantially development of composite materials. However, the composites losses it properties during secondary processing methods such as drilling, and cutting. The main objective of this paper is to study the loss of strength in composites while cutting serial fastener holes for mechanical joints of structures. The design is to be made such that the loss in strength is reduced considerably by selecting an exact combination of the parameters like (E/d, K/d ratios). Finally, the theoretical values are compared to the Ansys values.
