“…It has been proposed that the critical mean free distance [70] corresponds to either a transition from plane stress to plane strain conditions [71], or is due to the interaction of the stress field around neighbouring particles [72]. Figure 22b shows the measured fracture toughness versus the calculated mean free distance for specimens used in the present work.…”

The mechanical properties and fracture behaviour of epoxy-inorganic micro- and nano-composites

2006

Hybrid materials have been formed using an epoxy polymeric matrix and a range of inorganic particles, including mica and organically-modified montmorillonites ('organoclays'), with various concentrations of the silicate modifier up to about 30wt.% depending upon the viscosity increase induced by the presence of the silicate. Wide-angle and small-angle X-ray scattering plus transmission electron microscopy were used to identify the morphologies produced, which included particulate, intercalated and ordered exfoliated. The modulus of these composites increased with the weight fraction of silicate.

“…Rubber tends to improve the toughness of the epoxy by preventing the propagation of cracks and boosting the strain capability. Rubber particles induce the formation of microvoids and activate the yielding processes of the matrix [5]. A substantial amount of energy is dissipated within the plastic zone near the crack tip.…”

The effect of nanosilica on compressive properties of an Epikote 828 epoxy at room temperature was studied. A 40 wt% nanosilica/epoxy masterbatch (nanopox F400) was used to prepare a series of epoxy based nanocomposites with 5-25 wt% nanosilica content. Static uniaxial compression tests were conducted on cubic and cylindrical specimens to study the compressive stress-strain response, failure mechanisms and damage characteristics of the pure and nanomodified epoxy. It was found that the compressive stiffness and strength were improved with increasing nanosilica content without significant reduction in failure strain.The presence of nanosilica improved ductility and promoted higher plastic hardening behaviour after yielding in comparison with the unmodified resin system. This result suggested that nanoparticles introduced additional mechanisms of energy absorption to enhance the compressive properties without reducing the deformation to failure.

“…The peaks in graph shows the energy dissipation or energy absorption means whether the reaction in the material is exothermic (energy dissipation shown by EX) or endothermic (energy absorption shown by EN). The area under the endotherm or exotherm is related to the enthalpy of the thermal event, ΔH [8][9][10]. Figure 3a shows thermogram of epoxy with 10 wt% of coconut shell particles and 10 wt% of hardener.…”

Frequent use of various types of green composite in different applications has led to the great development in material science technology. Coconut shell which is generally considered waste material is been analysed here to get its desired properties and characteristics. Basically composite particles are studied using various macroscopic and microscopic approach and with various advance techniques like Scanning electron microscopy (SEM), Water absorption and Thickness swelling test, Thermal analysis, Thermo Gravimetric analysis (TGA) and Differential thermal analysis (DTA). In our work we have focused on the thermal analysis of coconut shell particles using TGA and DTA technology and finally the conclusion is made regarding the feasibility of using Coconut Shell Particle in Application of green composites.
