Abstract

Many materials are used in the field of aeronautical such as glass fiber, aluminum and so on. The application of composites materials are growing from customary areas (Aircraft engineering) to various fields (marines, automobile industry, civil engineering) because of the required qualities that can be attained by other constituent materials. In aeronautical industry, Carbon fiber reinforced composites are used for the manufacturing of different components of aircraft with the tight mechanical requirements. This paper discussed about the carbon fiber/epoxy and their strength compared to other composites. To know better understanding of mechanical properties of composites made from the epoxy resin and reinforced carbon fiber, different types of tests such as flexural strength, tensile strength, and compressive asset. The epoxy mastic works to improve the compressive property of composites. And this paper show the effects when carbon nanotube or nano-clay is added to the matrix of carbon fiber and epoxy. Keywords: Carbon Fiber, Epoxy, Flexural, Compressive, Tensile Strength

Introduction

Polymers are the attractive materials because of the low density compared to others. The demand of this material is increasing continuously because of they have an excellent mechanical properties. It is clear to all that the tension strength is stronger than the compression strength in the most advanced fiber. This property is because of the micro buckling of fibers that are entrenched in the medium governed the compressive forte of unidirectional amalgams with the fiber waviness that being the major factor. In structural application of composites, compressive properties are weak parts. In the manufacturing of high-speed rockets, aircrafts, and other related space and high temperature resins or electronics, are used as composite materials. The major load is shared by the reinforcements when a compound comprises of fiber cavalries that is isolated in a fragile matrix like epoxy/ carbon complex. This fiber bear almost all load. The stiffness and strength of constituent fiber control the stiffness and strength of such complexes (Banakar and Shivananda, 2012).

Carbon Fiber Reinforced Polymers (CFRP)

A significant improvement is offered by Carbon Fiber Reinforced Polymers (CFRP) over current conventional materials in aeronautical industry. It is a new class of polymer composites that consist multiple layers of fibrous materials. Because of their advanced properties this new class is used for many purposes like packaging, automotive, electronics, and construction industries. They are used to produce dissimilar physical constituents such as landing-gear doors, flaps, aileron and other structural parts. One of these advanced properties is they have high forte to stiffness and weight to weight ratios. Above the other monolithic constituents, these complexes have exclusive benefits such as high stiffness, high strength, corrosion resistance, long fatigue life, wear resistance, environmental stability and low density.

The complexes of laminates are vulnerable for motorized damage after come in the contact with tension, flexural and impact that results in the failure of materials. Though there is a reason of limiting using this in manufacturing practice. These reason are absence of dependable experimental processes that determine the mechanical characteristics of armored amalgams, complications in the mathematical exhibiting of distortion processes and the assessment of the load-carrying aptitude of protected structure and the prerequisite of new more reasonable manufacturing procedures.

CFRPs’ motorized properties can be dogged by constitutes properties, composite’s assembles, manufacturing technique and mode of collaboration at interfaces/matrix. By the known properties of constitutes, many mechanical factors of complexes can be determined. Still, the application of arduous mathematical solutions is not possible at all times because of the extreme sensitivity of some factors as strength, to the effects of other features that cannot be accounted completely’ (Rahmani et al., 2015).

Carbon Sources as a Suitable Material

Carbon and Graphite, both are the high temperature materials that also have a high strength and stiffness properties. These properties are maintained at a constant temperature of up to 2500°K. Composites of carbon fiber have many application such as biomedical, aeronautical, industrial, space and defense applications. The requirement of these supplies is that place where the system is exposed to extreme temperatures. They are used for high performance principles such as solid rocket motors. Now these days, the composites of carbon are used in military and commercial applications. A distinctive combination of chemical, mechanical and physical properties such as high strength and thermal resistance high modulus is contained by carbon fibers.
