Vegetable Fibre

A novel fibre composite consisting of natural vegetable fibre as the reinforcer and plasticised natural vegetable fibre as the matrix was studied. By means of cyanoethylation and chlorination, pine sawdust and chopped sisal were converted into thermoplastics and then compounded with sisal and ramie fibres. The natural fibre composite not only exhibits properties similar to those of conventional fibre composites, but also is characterised by easy processing, enviromental frendliness, low cost and capability of tailoring property due to the physically heterogeneous nature.

Bleaching Treatment

Food packaging has seen a growth in the use of materials derived from renewable resources such as poly(lactic acid) (PLA). However, the initial costs to produce bioplastics are typically high. Tropical fruit waste as naturally sourced fibres, such as jackfruit skin, can be used as a cost-reducing filler for PLA. The main objective in this study is to fabricate a low-cost natural fibre-reinforced polymer that potentially applies in packaging with the aid of bleaching treatment. The treatment shows a rougher surface fibre in Scanning electron microscopy (SEM) micrographs and it is expected to have better mechanical locking with the matrix, and this is found similar with a Fourier-transform infrared spectroscopy (FTIR) analysis. Unfortunately, fibre insertion does find low tensile performances, yet bleached-fibre composites improved its performance significantly. A similar situation was found in the thermal characterization where a low-thermal stability natural fibre composite has lower thermal behaviour and this increased with bleaching treatment. Besides, bleached-fibre composites have a longer service period. Besides, a 15 wt% thymol insertion inhibits the growth of Gram-positive bacteria in the composites and the non-treated fibre composite has better thymol effects. The 30 wt% of the bleached-fibre insertion composite has a high potential to reduce the cost of bioplastic products with minimum alterations of overall performances.

Kenaf Composites

Due to positive impact on the environment, biodegradable composite materials are of growing interest. This study used cellulose acetate, a derivative of cellulose, as the matrix for its solubility and flexibility. Kenaf composites have been used in furniture, ceiling panels, and fences. The aim is to prepare composites with plasticized cellulose acetate and natural fibre. The kenaf fibres were surface treated to remove impurities, in particular, hemicellulose, wax, and lignin. Chopped kenaf was added to dissolve cellulose acetate and cast on a Petri dish. After solvent has evaporated, the composite was compression moulded. The thermal and mechanical properties of the kenaf cellulose acetate composite were characterised. From thermogravimetry, the composites were shown to be stable until moisture began evaporating. As a hydrophilic material, cellulose is sensitive to moisture. The mechanical properties of the composites were analysed under high humidity. Dynamic mechanical analysis showed that these properties changed slightly with humidity.

Natural fibre composites are the promising replacement for synthetic fibre owing to their improved properties, and more importantly, natural fibres are biodegradable and of low cost. These characteristics have made them viable for contemporary engineering and structural applications. However, large scale production of natural fibre composites is in prone because of the challenges in manufacturing and machining. Fibre composite exhibits poor machinability characteristics owing to their heterogeneous and anisotropic behaviour. To overcome this problem, various steps and new methodologies have been established in the view to produce quality machining in natural fibre composites. In recent years, the possibility of conventional machining in natural fibre composites was also discussed. In the present review study, an effort has been taken in studying the fibre composite’s machining characteristics and their failure mechanism in both conventional and unconventional machining. The influence of process parameters in machining different natural fibre composites is also discussed.

In this paper a study of concurrent engineering in the development of product from natural fibre composites is presented. As far as the natural fibre composites are concerned, concurrent engineering is strongly linked to the design for sustainability because the design of natural fibre composite products fulfils the requirement of the design for sustainability, i.e. design for well-being of future generation. A study of the development of food packaging materials has been conducted. This study involved the development of sugar palm starch bio-polymer, selection of the most suitable bio-polymer, development of sugar palm fibre reinforced bio-polymer composites and design for food packaging of sugar palm fibre, specifically the sugar palm polymer composites.

Fibre Composites

The growing awareness about sustainable development, environmental ecology and new legislations has led researchers to focus attention on bio fibres reinforced composites. In this field research has been done on many fibres but fibres such as banana, coir, bagasse, jute have gained importance in the recent decades. The main advantage of the natural fibre based composites materials being their low cost, easy availability, low density, acceptable specific properties, ease of separation, enhanced energy recovery, C02 neutrality, biodegradability and recyclability in nature. The attention is being given to the development of natural fibre composites is to explore value-added application avenues for their use and also for a sustainable and economical use of easily available natural material in hand. Agricultural waste is a very good example of such naturally available material and it can also be used to prepare composite materials for commercial use this has a very significant advantage over other natural fibres as its abundance and because of almost no cost.

Increasing concern about global warming and depleting petroleum reserves and the high cost of petroleum products had made scientists to focus more on the use of natural fibres such as rice husk, baggase, coconut husk, hemp, sisal, jute, flax, banana etc. Past decade has shown many efforts to develop composites to replace the Petroleum and other non-decaying material products. Reinforcement with natural fibre in composites has recently gained attention due to low cost, easy availability, low density, acceptable, strength full, stiffness, ease of separation, enhanced energy recovery, biodegradability and recyclable in nature. Natural fibre composites are suitable as wood substitutes in the construction sector. All these have excellent physical, thermal and mechanical properties and can be utilized more effectively in the development of composite materials. In this connection, an investigation has been carried using rice husk, a natural fibre abundantly available in India.
