Abstract:

This thesis presents the results of an experimental and analytical study of the high strain rate behaviour of ceramic particle-reinforced metal matrix composites (MMC). Two MMC systems, both based on the 6061-T6 aluminum matrix, were selected. The first is an alumina reinforced system, made by a liquid metallurgy (LM) route, with 10, 15 and 20% particle volume fractions. The second is a silicon carbide system, made by powder metallurgy (PM), with 0, 15 and 30% particle volume fractions. Unreinforced 6061-T6 and 7075-T6 were also included for comparison.

Abstract:

Metal matrix composites (MMCs) are emerging as advanced engineering materials for application in aerospace, defence, automotive and consumer industries (sports goods etc.). In MMCs, a metallic base material is reinforced with ceramic fiber, whisker or particulate in order to achieve a combination of properties not attainable by either constituent individually. Aluminium or its alloy is favoured as metallic matrix material because of its low density, easy fabricability and good engineering properties. In general, the benefits of aluminium metal matrix composites (AMCs) over unreinforced alumini

The effects of reactive metal particles on the microstructure and mechanical properties of epoxy-based composites are investigated in this work. To examine these effects castings of epoxy reinforced with 20-40 vol.% Al and 0-10 vol.% Ni were prepared, while varying the aluminum particle size from 5 to 50 microns and holding the nickel particle size constant at 50 microns. In total eight composite materials were produced, possessing unique microstructures.

However, due to its inferior properties at high temperature, it is not suitable to electrical contact devices that carry heavy loads or provide superior performance. Tungsten has high melting point, excellent high temperature strength and low coefficient of heat expansion. Copper has good electrical (thermal) conductivity and low melting point. W-Cu composite material is fabricated by using powder metallurgy to be provided with specia

Abstract:

Highly filled polymer composites, such as polymer concrete (PC), suffer from setting stresses generated during the cure of the resin binder, when polymerization shrinkage is hindered by the close packing of filler and aggregate particles. Setting stresses impair significantly the strength of the cured composite. Current zero-shrinkage and expanding polymer concrete formulations achieve these properties with a sacrifice in strength. In this investigation, a novel system was developed for producing zero-shrinkage and expanding polymer concrete composites with concomitant enhancement in strength.

To estimate the performances of the PP/Talc composites, mechanical properties, heat deflection temperature (HDT), thermomechanical analysis, and isothermal crystallization characterization were conducted. Incorporating talc particles increased the tensile strength, flexural properties, and HDT of the PP matrix, but reduced the elongation at break and notched impact strength. Moreover, the inclusion of talc particles in PP/Talc composites induced heterogeneous nucleation and considerably redu

Abstract:

This study introduces a time-dependent micromechanical model for a viscoelastic-viscoplastic analysis of particle-reinforced composite and hybrid composite. The studied particle-reinforced composite consists of solid spherical particle and polymer matrix as constituents. Polymer constituent exhibits time-dependent or inelastic responses, while particle constituent is linear elastic. Schapery's viscoelastic integral model is additively combined with a viscoplastic constitutive model. Two viscoplastic models are considered: Perzyna's model and Valanis's endochronic model.

Magnesium and magnesium alloy are the lightest structure material, but have smaller elastic modulus, tensile strength and yield strength than aluminum alloy.
