Project Abstract

Composite materials are obtained by combining two or more materials having different characteristics at certain conditions and at certain rates forehead macro structure  for the desired purpose. A composite material usually consisting of  matrix resin or metallic  matrix resin which has  lower modulus and strength  and reinforcement phase which dispersed in the main phase. Carbon fiber composite materials are used as reinforcing material carbon fibers are used most commonly in the form of woven cloth. Fibers are woven in the fabric form to achieve equal strength and  increase the strength of the material in all directions, Woven polymer matrix composites are gaining in popularity or manufacturing aerospace structures and automobile structures because of their ease of use , have a symmetric and balanced material properties. The scope of this study is firstly made ​​the overall presentation of composite materials then determined the properties and common areas of carbon fiber-reinforced composite materials.

 

In our study, the use of modified epoxy resin systems with carbon nanotubes as the matrix material are planned for  production of carbon-fiber-reinforced composite material. Epoxy resin systems are widely used in industries of the aviation, marine, automotive, sporting goods due to strength, durability and light weight fiber-reinforced composite materials. Modified resin systems  obtained by strengthening epoxy resin systems with  carbon nanotubes to increase the mechanical, thermal properties and electrical characteristics of epoxy resins and resin systems It is expected to obtain crack growth resistance in the carbon composite materials, fiber direction perpendicular to the fiber direction of the increase in strength, the temperature drop in the coefficient of expansion, obtain easy and ready systems to use in the hot-melt prepreg applications, better conductivity and anti-static properties by using modified epoxy resin with carbon nanotubes as matrix material systems. Making tensile and compression tests, are planned  in order to investigate of the effect different woven fabric construction structures, linear density, warp and weft yarn density, weft and warp yarn number, modified resin systems with carbon nanotubes  as  the matrix material  on the mechanical properties of the composite material. In addition to these the DSC and TGA analysis are planned to determining the thermal properties of composite material and SEM analysis for determination of the surface properties
