تجزیه و تحلیل عملکرد جهت گریخت در ورقه های کامپوزیت

With advancement in Material Sciences new types of materials are being invented and researched every day. Composite materials are globally used in aircraft design to decrease emissions and significant weight reduction. Advanced composite materials, which are usually continuous fibers (mostly carbon and glass) within a polymer matrix provide superior material properties than metals and enable lighter structural designs to be achieved in aerospace applications. In recent years, advanced composites have replaced traditional structural materials in aircrafts to a significant extent (e.g. Boeing 787, Airbus A350, with more than 50% composites by weight. The evaluation technique generally involves the implementation of ANSYS & MATLAB softwares that help in designing, drafting, and analysis. The scope of this paper is to highlight the researches done in composite laminates, new fibers and resins and to create future applications for composites. Eco-friendly resins will replace recycled plastics and bio-based polymers by composites. The present paper entitled “Performance Analysis of Ply Orientation in Composite Laminates” is the work done to perform the analysis on CFRP laminate with in-plane loading condition. In this research the mathematical calculation of determining the failure criteria of the laminate with ply orientation of [90/0/0/-45/+45]s is done by writing stress program on MATLAB and further analysis is performed using ANSYS. After obtaining both the results the design is validated.
