TAILIEUCHUNG - Báo cáo " Experiment for Bending Analysis of 3-phase Composite Plate in Ship Structure "

Composite is a material composed of two or more component materials to obtain better properties. 3-phase composite is usually added with reinforced fibers and particles. This report presents an experimental study on the bending of some 3-phase composite plates for Vietnam’s shipbuilding industry. The studied composite is made of polyester matrix, glass fiber and titanium dioxide particle (TiO2). The numerical study, in which the interaction between the matrix and particle is taken into account, shows good agreement with the experiment. . | VNU Journal of Science Mathematics - Physics 26 2010 141-145 Experiment for Bending Analysis of 3-phase Composite Plate in Ship Structure Nguyen Dinh Duc1 Dinh Khac Minh2 1 University of Engineering and Technology VNU E3-144 Xuan Thuy Cau Giay Hanoi Vietnam 2Shipbuilding Science and Technology Institute Hanoi Received 9 June 2010 Abstract. Composite is a material composed of two or more component materials to obtain better properties. 3-phase composite is usually added with reinforced fibers and particles. This report presents an experimental study on the bending of some 3-phase composite plates for Vietnam s shipbuilding industry. The studied composite is made of polyester matrix glass fiber and titanium dioxide particle TiO2 . The numerical study in which the interaction between the matrix and particle is taken into account shows good agreement with the experiment. 1. Introduction To improve both the mechanical and physical properties composite can be reinforced simultaneously with both fibers and particles thus 3-phase composite appears. The bending problem of anisotropic plate and shell is studied in 1 2 . The bending of composite is studied in 2 3 . In 4 we investigate the bending problem for 3-phase composite taking into account the shear effect and in 5 we take into account the creep effect. Recently the present authors have published some experiments to determine the elastic modules for 3-phase composite with different volume ratio of fiber and particle. Our purpose in this paper is to continue the experiments for the bending of 3-phase composite plates used in Vietnam s shipbuilding. The material is made of polyester matrix reinforced by glass fibers and titanium dioxide particles. The formulas used for the calculation are from 6-8 and 4-5 9 . 2. Prepare the samples The samples dimension is 500mmx300mm. It is made of 6 plies the stack sequence is 07 457-457 457-45790 . The plate s thickness is mm. The material s components are AKAVINA polyester glass .
