Abstract

Stacking plates of composite materials, which are common used today have increasing in demand because of its unique characteristics. It has the properties of uneven quality and anisotropic nature unlike general metallurgical materials as the staking plates of composite materials are in the combination of different types of fiber materials to produce continuous reinforced polymer composite such as laminated polymer composite. Therefore, in this study, stacking plates of laminated polymer composite materials were manufactured using hand lay-up, cured polyester resin, woven roving glass fiber and chopped strand mat. Then it is made by changing woven fiber glass orientation angles and also some samples in combination with chopped strand mat (CSM). The samples after that are tested in the thickness direction for six specimens, three with different fiber orientations, [0/90/0/90]2S, [0/90]2S[0/45]2S, [0/45/0/45]2S and plus another three sample in orientation and combination, [CSM/CSM]2S, [CSM]2S[0/90]2S, [CSM]2S[0/45]2S which is chopped strand mat .In this study, it was to obtain the flexural strength results by carrying out three-point bending testing and in order to find out the effect of that orientation according to the samples by following the ASTM D790 test method.
