Experimental study on young’s modulus E of a polymer composite reinforced by nano titanium dioxide particles

There are many formulas proposed by different authors in order to determine elastic modules for composite filler particles. This article aims to present the experiment’s results and to review some formulas for determining Young’s modulus of elasticity E of the polyester filler titanium dioxide particles composite. The results showed that there was a relatively good fit between theory and practice of some formulas. | Vietnam Journal of Mechanics, VAST, Vol. 34, No. 1 (2012), pp. 19 – 25 EXPERIMENTAL STUDY ON YOUNG’S MODULUS E OF A POLYMER COMPOSITE REINFORCED BY NANO TITANIUM DIOXIDE PARTICLES Nguyen Dinh Duc1 , Dinh Khac Minh2 of Engineering and Technology, VNU 2 Shipbuilding Science and Technology Institute 1 University Abstract.

INTRODUCTION Composite material consists of two or more distinct components to obtain a new material with better properties. Such components include matrix material and filled materials including fiber, fabric, particles, and so on. The matrix material aims to ensure the linkages among all the composite components, which will resist all external acting on the composite including heating, physical, and chemical loads, while the filled components are used to improve the mechanical properties (stiffness and strength) of the composite [1, 2, 3]. The composite reinforcement components typically are composed of fiber, fabric, or particles. The fibers and fabrics increase the bearing capacity of the composite structure, while the particles often reduce crack, plastic deformation and increase the waterproofing capacity. Hence, the combination of fiber and particles in the composite material is able to make the composite product more perfect and meet the requirements of modern technology [4, 5, 6, 7]. Recently, the reinforce of polymers using piezoelectric particles, ferromagnetic particles, titanium dioxide particles,. not only increases the strength of .
