Wood fibre reinforced polypropylene composites at fibre content 50% by weight have been prepared and different types of wood fibres (hard wood fibre, soft wood fibre, long wood fibre and wood chips) were treated with coupling agent (MAH-PP) to increase the interfacial adhesion with the matrix to improve the dispersion of the particles and to decrease the water sorption properties of the final composite. The present study investigated the tensile, flexural, charpy impact and impact properties of wood fibre reinforced polypropylene composites as a function of coupling agent and fibre length and structure. From the results it is observed that wood chips-PP composites showed better tensile and flexural properties comparative with the other wood fibre-PP composites with the addition of 5%MAH-PP, which is around 65% and 50% for tensile strength and flexural strength respectively. Hard wood fibre-PP composites showed better impact characteristic values comparative to other wood fibre-PP composites with the addition of 5%MAH-PP and damping index decreased about to 60%. Charpy impact strength also increased up to 60% with the addition of 5%MAH-PP for long wood fibre-PP composites. Water absorption and scanning electron microscopy of the composites are also investigated.

Wood Fibre Reinforced Polypropylene Composites: Effect of Fibre Geometry and Coupling Agent on Physico-Mechanical Properties

Composite materials derived from biodegradable starch polymer and jute strands

As major historical periods such as Stone Age, Bronze Age, and Iron Age, the development of new materials was the fundamental to all the periods In the present investigation, a new hybrid composite with epoxy as a resin and reinforcing both biowaste (jute) and traditional fiber (glass) as continues layered mat composites and also study experimentally the effect of the stacking sequence on tensile, flexural, and interlaminar shear properties Composites were prepared by using hand lay-up technique All the laminates were prepared with a total of four piles, by varying the position of glass and jute One group of all jute and glass laminate was also fabricated for comparison purpose Specimen preparation and testing were carried out as per ASTM standards Tests were conducted on INSTRON H10KS Material Test System at room temperature using automatic data acquisition software The results indicated that the jute fiber and hybrid composite give encouraging results when compared with the neat epoxy The morpho

In the last two decades, the fibre reinforced composites have attracted substantial importance as a potential structural material for residential housing construction and is largely found in nonstructural housing components. Research and development efforts are being made to use bast fibres (comes under the classification of plant fibres) as reinforcement for the automotive and building industries. Bast fibres, a relatively new group of environmental friendly materials are in considerable demand in recent years by unifying technological, economical and ecological aspects. Bast fibres are receiving increasing attention as reinforcement in polymeric materials in composites due to the shortage and environmental hazardous of non-renewable resources. The use of bast fibres offer a number of advantages, since they are derived from a renewable resource, require low energy inputs in their manufacture, and can be disposed of at the end of their life-cycle by composting. Further the bast fibre reinforced polymer composites is of low density and cost as well as having satisfactory mechanical properties. The aim of this paper is to provide a consolidated report of the researches in the field of different bast fibres (banana, flax, hemp, jute, kenaf and ramie) reinforced polymer composite including the effect of chemical treatment with its physico-mechanical properties and their applications.

A review on physico-mechanical properties of bast fibre reinforced polymer composites

This article consists of the two parts. In the first part the nature of jute fiber, productivity, advantages, disadvantages, its composition etc. have been described. The jute fiber is also compared with the glass fiber. Inspite of some advantages, this natural fiber possess some drawbacks and thus needs chemical modification. For modification of fiber-matrix interaction i.e.to reduce jute polymer interactions and to facilitate wetting, the use of compatibilisers is also mentioned. In the second part different types jute composites have been described. The role of jute composite as wood substitute is explained. The different methods of jute composite manufacture with its potentials & prospects are also described in a nutshell.
