Mechanical properties of particulate goat bone reinforced epoxy composite were investigated in this research. This was aimed at assessing the suitability of the developed composites for biomedical applications. The combination of the two materials for the development of the composites was targeted to meet good surface compatibility in addition to the structural compatibility needed as biomateri...

Metal matrix composites (MMCs) have superior mechanical strength and wear resistance as compared to base alloy. Aluminium matrix reinforced with low density discontinuous particulate composites has good potential in automobile and aerospace applications. The main challenge is to produce the light weight composite in a cost effective way to achieve the greater properties. In the present study, a...

In recent years, the improvement of properties of natural fibre reinforced laminates over the pure polymeric matrix has been thoroughly investigated with the aim of providing a possible replacement of E-glass fibre reinforced composites for some large-volume applications. In the present study, the properties of a jute/polyester laminate are compared with those yielded by two E-glass fibre woven...

In this paper the effect of various chemical treatments on the damping property of jute fiber reinforced green composite is discussed. The surface of the jute fiber was modified by alkali, permanganate, benzoyl chloride, malic anhydride and silane treatments. Several samples of unidirectional composites were prepared with treated jute fibers as well as untreated jute fibers. Matrix used is epox...

The main advantage of multidirectionally reinforced composites is the freedom to orient selected fiber types and hence derives the benefits of varying fibre volume fractions and there by accommodate the design loads of the final structure of composites. This technology provides the means to produce tailored composites with desired properties. Due to the high level of fibre integrity with throug...

The influence of nanoscale reinforcement on the mechanical behavior of ultrafine-grained composites was studied. Al 5083 (Al– 4.5 Mg–0.57Mn–0.25Fe) composites, with grain size of 115 nm and B4C reinforcement size of 38 nm, were fabricated via cryomilling and consolidation. The result reveals that the presence of nanoparticles enhances strength by interacting with dislocations, while simultaneou...

Interphases in unidirectional fiber-reinforced composites under transverse loading are modeled using an advanced boundary element method (BEM) based on the elasticity theory. The interphases are treated as elastic layers between the fiber and matrix, as opposed to the springlike models in the BEM literature. Stress intensity factors for interface cracks between the interphase and the matrix are...

This study focused on the contribution of micromechanical parameters on the macro-mechanical response of short fiber composites, namely polypropylene matrix reinforced by glass fibers. In the framework of this paper, an attention has been given to the glass fibers length, as micromechanical parameter influences the overall macroscopic material’s behavior. Three dimensional numerical models were...
