Day By Day

The usage of composite material has been increasing day by day over the years due to the excellent properties being offered by them such as lower volume-to-weight ratio, improved toughness, recyclable, environment friendly and also due to their short cycle productivity, easiness in fabrication, long lasting life span etc. This work presents study of mechanical and tribological behaviour of ABS polymer matrix filled with micron-sized inorganic and Natural / Green fillers. The main purpose behind this work is to compare the performance of composites with different class of fillers. The experimental results unveil that the composite with inorganic fillers perform better than with natural based fillers.

Waste newspaper fiber was filled in the collagen cross-linked by glutaraldehyde. The effects of deinking fiber, glycerol dosage, glutaraldehyde dosage on the mechanical properties of composite were investigated. It is found that the deinking treatment increases the strength of the composite material. The composite has better mechanical properties under the preparing conditions as follows: waste newspaper fiber content 10%, glutaraldehyde dosage12.5%, glycerol dosage 12.5%, pH 9.7, 60°C for 2h. The tensile strength and elastic modulus are 4.98Mpa and 0.09Gpa, respectively.

Abstract Now days, green composite materials are now gaining popularity for the various industrial applications. It is a combination of naturally occurring reinforcement like jute, sisal, flax, hemp, and kenaf; and matrix materials like biopolymers or bio resins which have been derived from starch, and vegetable oils. It is becoming more desirable due to its properties like biodegradability, renewability and environment friendly. The present paper presents the various natural fibers and their combinations with biopolymers. The paper also reflects the key issue related to hydrophilic nature of natural fibers and their remedies for a good fiber and bio polymer adhesion. Furthermore the strategy used and major attributes of the green composite are also discussed.

The Matrix

Basalt as a filler in a polymer-based composite material fulfils the demand of being natural, environment-friendly material for the production of various composite materials. The material could be used as protective layer and the abrasion should be tested in order to evaluate the properties of the material. The cavitation test enables the evaluation of the possible service in conditions that simulate the extensive erosion. The presence of basalt in the matrix improves the resistance to cavitation. The possibility to further improve the material could be obtained using the reinforcement of the matrix itself by incorporation of submicron ceramic particles into the composite. The obtained hybrid composite material with the addition of reinforcement in the matrix further improves the cavitation resistance.

Strength And Stiffness

Increasing population has led to numerous disabilities. One such disability which should be taken into account is related to human gait. Polio patients mainly suffer from this kind of disability due to which their muscles get weakened and they are unable to walk properly. The handicapped patients require an appliance with the help of which they can walk without any difficulties and the appliance acts as an aid for the correct positioning of their joints. Presently Aluminum Alloy based calipers are used but still the patients urge for better comfort. The requirement apart from more strength and stiffness, durability at lesser cost, environment friendly and light weight. Composite material is one such material which provides lower weight to volume ratio, high strength and stiffness at lesser cost. The purpose of the authors is to compare the mechanical properties of presently used aluminum calipers with polymeric thermoset based matrix (Carbon cloth with epoxy) based on CAD tools. The comparison reveals that thermoset based matrix will provide the maximum strength and firmness when compared to presently used Aluminum based calipers and model designed on CAD tools. Hence, the usage of the composite material will help the researchers design orthotic calipers which will have higher strength at a lower weight.

The stearate surface modified LDHs S-NiMgAl-Y was rapidly synthesized based on the coprecipitation coupled with the microwave hydrothermal treatment. The cone calorimeter data confirmed that composite S-NiMgAl-Y/EVA has the good functions of both the flame retardancy and smoke/toxic gas suppression. The tensile strength of S-NiMgAl-Y/EVA was increased to the maximum value of 25.6 MPa when the addition of 10 wt.% S-NiMgAl-Y to EVA. This value is markedly larger than that of the pristine EVA equaling 20.8 MPa. The composite material developed in the present work greatly contributes to the processing and application of the fire retardant material.
