Abstract Current research focuses on optimizing various quality characteristics for kerf geometry generated through laser cutting of Coir fibre/carbon fibre/epoxy resin hybrid composite adjacent to straight cut profile employing pulsed CO 2 system. The Kerf taper (KT) and the Surface roughness (SR) are main parameters discussed. Dependent significant process parameters, namely gas pressure, spe...

The purpose of the study is to delineate the impact of national and industry-specific government interventions and the influence of political parties in power. The study employs an interrupted time series design from the annual national coir export data (1970-2012) published by the Coir Board. The study concludes by highlighting that the significance of economic environment has a greater impact...

In the context of sustainable development which is a balancing act between the fulfilment of human needs and the protection of the natural environment, the use of natural fibers such as coir in geotechnical applications is desirable. Reinforcing the soil with coir fibers/coir geotextiles is a cost effective solution to the ground/soil improvement problems. The effects of fiber parameters on the...

In this study, physical, mechanical, and flammability properties of coconut fiber reinforced polypropylene (PP) composite panels were evaluated. Four levels of the coir fiber content (40, 50, 60, and 70 % based on the composition by weight) were mixed with the PP powder and a coupling agent, 3 wt % maleic anhydride grafted PP (MAPP) powder. The water resistance and the internal bond strength of...

Ideal bacterial support medium for fixed film denitrification processes/bioreactors must be inexpensive, durable and possess large surface area with sufficient porosity. The present study has been focussed on removing nitrate nitrogen at two different nitrate nitrogen loading rates (60 (NLR I) and 120 (NLR II) mg l(-1)) from simulated aquaculture wastewater. Coconut coir fibre and a commerciall...

This research work developed and evaluated the mechanical properties of coconut fibre reinforced low density polyethylene (LPDE) composite material. The effect loading on properties: tensile, flexural, impact material have been investigated. Also carried out was water absorptivity Sample categories were prepared by varying contents weight at 0%, 10%, 20%, 30%. aim is to reduce excessive waste d...

In recent years, the growth of environmental awareness has increased interest in development biocomposites which are sustainable materials with an excellent price–performance ratio and low weight. The current study aimed to obtain characterize prepared by thermoforming using coir fibres as reinforcing material polypropylene matrix. were produced different fibres/polypropylene ratios characteriz...

It is often suggested that optimization of the fibre-matrix interfacial adhesion essential to improve mechanical performance natural fibre reinforced thermoplastic compounds. The use such composites in many applications requires characterisation over a range temperatures. This paper presents study on measurements coir with various polyolefin matrices at room temperature. We then present novel a...

Due to their high mechanical and physical properties, natural fibre-based composite materials have been important in many fields of application for four five years. The chief intention the current study is determine water retention features under ambient conditions. Coir pineapple leaf fibre were used as a reinforcement, aluminium oxide additives, polyester matrix. hybrid resources laminated by...
