Fibre Reinforced Composites

Fibre reinforced composites have been an essential concern in various fields, especially in the field of aerospace owing to its high strength to weight ratio, toughness, corrosion resistant and low cost. Natural fibre reinforced composites have produced better results in mechanical properties like impact, toughness and fatigue strengths when compared to synthetic fibre reinforced composites. Recently researches have been conducted on different varieties of natural fibres for use in plastics such as jute straw, wood, rice husk, wheat, barley etc. Natural fibres have also attracted the attention of researchers due to its availability, renewability, degradability and most importantly ecofriendly. In this work an attempt is made to improve the mechanical properties of the composite and also to enhance the compatibility of the fibres with the matrix. The composite is prepared by reinforcing banana fibres into unsaturated epoxy matrix using hand layup method. Mechanical properties such as tensile strength, flexural strength and hardness strengths are carried out on the specimens made by reinforcing with 5%, 10 % and 15 %concentration of banana fibre by weight. The results showed that the composite with 15% concentration of banana fibre produced higher tensile strength of 21.43 MPa, flexural strength of 0.895 kPa and Shroud hardness of 59.3.

AbstractThe interest in natural fibre reinforced composites is growing in industrial applications due to natural fibres being an attractive alternative to synthetic fibres. However, it is necessary to improve the fire behaviour of the material because natural fibres have a high combustibility. The objective of this work is to evaluate the fire resistance of polymer composites reinforced with natural fibre fabric, using magnesium hydroxide as flame retardant for the polymeric matrix and alkali treatment for the fibre. The types of fabric are banana, banana with cotton and linen; and long banana fibre has been used for the formation of a nonwoven. The fire test is carried out based on ISO 9773 standard and the effect of the additive has been studied, chemical treatment, type of fabric and number of layers. Through statistical analysis, it is concluded that the flame propagation speed has a decreasing relation with respect to the percentage, but it decreases the mechanical properties considerably. In addition, the number of layers and type of fabric influence the fire properties. Finally, it is concluded that composites reinforced with linen fabric have the best mechanical properties, but banana nonwoven with 60% additive has the best fire behaviour.

Natural fibres offer environmental benefits such as biodegradable and can be obtained from renewable resources. However, there is lack of investigations done to characterize and compare different types and orientation done on the natural fibres. This paper determines the tensile strength of sugar palm fibres under various treatment processes. The composites were fabricated using woven sugar-palm fibre treated with alkali and acid and used epoxy resin as the matrices for the composite. The tensile test was done to determine the tensile strength of the composite and the surface morphological analysis was done using SEM. The results demonstrated that the composite with the alkali treated fibres produced higher tensile strength compared to untreated and acid treated fibres. With these properties, it shows that treated woven sugar-palm fibre composite can withstand high stress load during operation compared to untreated fibres reinforced composites.

In engineering, composites have indicated a more profound influence in the recent development of materials with high strength to weight ratio. The purpose of this work is to identify the different and specific properties which a composite possesses when various reinforcement fibres are used in different epoxy matrix material. Composite materials have a major role to play with meeting that requirement. Many natural fibre composite materials possess good mechanical properties but still lack in satisfying applications requirements and alternate for which is seen as sandwich natural fibre composites. In this investigation, an effort has been made to study the mechanical properties exhibited by sandwich epoxy composite reinforced with various commonly used natural fibres, namely Aloevera, Kenaf, Sisal, Jute and Flax. The polymer resin used as matrix is also varied using Epoxy LY556 and Epoxy GY250. The originality of this work is in the use of Epoxy GY250 to fabricate sandwich composites with five commonly available natural fibres and compare its performance to the more widely used Epoxy LY556. It has been determined through various mechanical tests, which particular epoxy resin bonds better with the natural fibres namely, jute, sisal, aloe vera, kenaf and flax thereby providing better tensile, impact and flexural properties. The investigation is hoped to provide an insight into how the environmentally friendly natural fibres interact with the varying matrix resins and how this interaction affects the mechanical properties of said composites.

Fibre Reinforced Composites

The increasing global environmental concerns and awareness of renewable green resources is continuously expanding the demand for eco-friendly, sustainable and biodegradable natural fibre reinforced composites (NFRCs). Natural fibres already occupy an important place in the composite industry due to their excellent physicochemical and mechanical properties. Natural fibres are biodegradable, biocompatible, eco-friendly and created from renewable resources. Therefore, they are extensively used in place of expensive and non-renewable synthetic fibres, such as glass fibre, carbon fibre and aramid fibre, in many applications. Additionally, the NFRCs are used in automobile, aerospace, personal protective clothing, sports and medical industries as alternatives to the petroleum-based materials. To that end, in the last few decades numerous studies have been carried out on the natural fibre reinforced composites to address the problems associated with the reinforcement fibres, polymer matrix materials and composite fabrication techniques in particular. There are still some drawbacks to the natural fibre reinforced composites (NFRCs)—for example, poor interfacial adhesion between the fibre and the polymer matrix, and poor mechanical properties of the NFRCs due to the hydrophilic nature of the natural fibres. An up-to-date holistic review facilitates a clear understanding of the behaviour of the composites along with the constituent materials. This article intends to review the research carried out on the natural fibre reinforced composites over the last few decades. Furthermore, up-to-date encyclopaedic information about the properties of the NFRCs, major challenges and potential measures to overcome those challenges along with their prospective applications have been exclusively illustrated in this review work. Natural fibres are created from plant, animal and mineral-based sources. The plant-based cellulosic natural fibres are more economical than those of the animal-based fibres. Besides, these pose no health issues, unlike mineral-based fibres. Hence, in this review, the NFRCs fabricated with the plant-based cellulosic fibres are the main focus.

Fibre Reinforced Composites

Composites are materials formed by the combination of two or more components that acquire better properties than the ones obtained by each component on its own. Composites have been widely used in the industry due to its light weight and good mechanical properties. To improve these properties several layers of reinforced material (e.g., carbon fibre) are overlapped which produce an increase in the fibre consumption. In this sense Tailored Fibre Placement (TFP) embroidery can offer good opportunity to reduce the consumption of reinforced fibre while improving the mechanical properties due to the alignment of the fibres in the effort direction. This study analyzes the performance of carbon fibre reinforced composites with Polyester resin made with TFP embroidery technology against flexural strength efforts and without using plain woven fabrics to demonstrate that the use of reinforcement fabrics in composites can be optimized by a curved alignment of the fibers. Two different structures were embroidered with TFP technology, one simulating a woven fabric with straight unidirectional alignment of fibres in horizontal and vertical direction, and a second structure made with curvilinear alignment of carbon fibers. After the study of the flexural mechanical properties an improvement of 18% was obtained in maximum flexural strength.
