| Abstract | ||
| The effect of fiber volume fraction on the flexural properties of the laminated composite test specimens constructed of two layers, one of them reinforced with glass fiber and the other layer reinforced with Kevlar fiber has been investigated experimentally. The results illustrate that tension stress decreases with the increase in fiber volume fraction of glass fiber of the lower layer while it increases with the increase of Kevlar volume fraction of the upper layer. As for compression stress, it increases with the increase in volume fraction of glass fiber of the lower layer while it decreases with the increase of volume fraction of Kevlar fiber of the upper layer. The results also show the maximum value of tension stress (= 25.3 MPa.) at Vf of Glass fiber (= 15 %) and Vf of Kevlar fiber (= 60 %), while the maximum value of compression stress (= -17.1 MPa.) at Vf of Glass fiber (= 60 %) and Vf of Kevlar fiber (= 15%). | ||
