Dana Luca Motoc, Ioan Curtu Dynamic Mechanical Analysis of Multiphase Polymeric Composite Materials


Abstract:
The paper aims to present a theoretical-experimental approach of a particular class of composite materials known as multiphase composites in order to retrieve its effective dynamic moduli and identify the major influencing factors on these variations. Supplementary, will be presented a two step homogenization concept based on the well known theoretical predictions from the micromechanics of composite materials approaches, the Mori-Tanaka that applies to the particle reinforced composites and Halpin-Tsai that applies to the random fibre composites. The theoretical values were compared with the experimental data, the later being retrieved during a two heating cycles with temperature ranging from -300C to 1600/2000C, in air, at a frequency of 1 Hz, using a DMA 242 C device, from Netzsch, Germany. The samples were manufactured using a self-developed technology. The samples were ceramics (Al2O3) and metal (Fe) reinforced particles embedded in small volume fraction along with random E-glass fibres (65%) into a polymeric matrix material. Keywords: composites, multiphase, polymer, dynamic modulus, testing
