Thermo-Mechanical Analysis for Characterization of Dynamic Properties of FRP Composite Materials

Abstract

The research study is designed to assess the delamination factor and develop strategies to mitigate or minimize delamination. When addressing the machining of composite materials, abrasive water jet machining emerges as a superior choice compared to conventional and non-conventional machining methods. Composite materials are being increasingly used in various applications like space, aircraft, marine, architectural and automobile sector because of their superior physical and mechanical properties. This work is to evaluate the mechanical properties of carbon kelvar, basalt and glass fabric reinforced composites will be fabricated using hand layup and vacuum bagging technique. In former research work TMA is widely used, thermo-mechanical analysis (TMA), applies static force to a material and watches the material change temperature or time varies. Its reports dimensional changes. Abrasive water jet machining provides some advantages over conventional and non-conventional machining process for cutting the composite materials like no thermal effect, high machining versatility and small cutting forces. In the present research work, the effect of abrasive jet machining parameters such as traverse speed, abrasive flow rate, standoff distance on delamination’s of glass fiber reinforced epoxy composite is investigated. It is found that optimum water pressure together with small standoff distance between the nozzle and work piece may be used whereas, the traverse speed should be moderate in order to reduce delamination in composites.
