Abstract

ABSTRACT:-This study deal with composite materials made of E-glass , carbon fiber with epoxy matrix at volume fraction 0.6 , by using mat lab 2008 a was used to state the deformation and strain in both x,y direction .
40*40 mm element was subjected to tensile stress in x direction with value 200,300,400 and 500 MPa with two angle θ=0 and θ=45 degree, the von miss stress distribution has been stated by using solid work at 400,500 MPa.
The results was showed when θ=0 glass fiber have value of strain more than carbon fibers, when θ=45 carbon fiber have value of strain more than glass fibers .the change in right angle gave us zero indicating when θ=0 ,and θ=45 the change in right angle gave us negative indication .the von miss stress at 500 MPa was low factor of safety .
Keywords:- composite material, mat lab, epoxy, strain, deformation.
