Processing of Epoxy-Nickel Matrix Composites Reinforced with Aluminum and Waste Elastomers

Abstract:

A mixture of structural functions can be accomplished using different reinforcements in epoxy-nickel matrix composites. In the frame of the common research project, mechanical and physical properties of the epoxy resin-nickel matrix composites containing extremely fin aluminum and fine waste elastomer powders were studied. A comprehensive study is given with different static and dynamic aspects as a function of composition, frequency and temperature. Two types of waste elastomeric powders were used for the reinforcement: Styrene-Butadyene Rubber SBR and Ethylene Vinyl Acetate (EVA). All of the composites were fabricated by mixing during 4h and then put in an ultrasonic dispersion for 1h. After that, a detail analyses has been carried out by means of Dynamic Mechanical Thermal Analysis (DMTA), microindentation and wear - scratch test. Dielectric properties (Permittivity (ε′)) and dielectric loss angle tangent (tan delta) were investigated using a Dielectric Thermal Analyzer (Rheometric Scientific) at three different frequencies (1 kHz, 10 kHz, 100 kHz) from room temperature up to 280°C. Wear of surface resistance measurement has been carried out by scratch test with a normal of 2.06N load with the frequency of 10Hz in two different number of cycles; 50000 and 100000. After the test, damaged zone were measured by 3D optical roughness meter to characterize damage occurred after the scratch test.
