Evaluation of Mechanical Properties of Sisal and Bamboo Fibres Reinforced with Polymer Matrix Composites Prepared by Compression Moulding Process

Today’s modern, dynamic world would be impossible to imagine without the concept of composite material advancement. Various studies are being conducted in this area in order to reach the desired level. In terms of compatibility, natural fibre reinforced polymer-based composites and synthetic fibre composites are very similar. Because they are lightweight, nontoxic, and nonabrasive, they are very popular with consumers. They are also readily available and affordable. Composite materials made from natural fibre have superior mechanical properties compared to those made from synthetic fibre. As part of this research, an epoxy-based composite with bamboo and sisal fibre reinforcement is examined. Reinforced with epoxy resin, bamboo fibre and sisal fibre are used to make composite materials. The effect of adding bamboo fibre and sisal fibre in various weight percentages on the mechanical behaviour of composites is investigated.

Tribological Studies of Bamboo Fibre Reinforced Epoxy Composites Using a BOD Technique

To reduce the emission of harmful materials into the ecosystem, researchers have been exploring the potential of manufacturing polymeric composites based on natural fibres. Although the large area of application of these materials has encouraged investigations of their performance under various loading conditions, less research has been conducted on their tribological behaviour. Hence, in this study, tribological tests were conducted on epoxy composites based on bamboo fibres. The wear performance of bamboo fibre reinforced epoxy was tested using various operating parameters, and the worn surfaces were examined using optical microscopy. The results revealed that the specific wear rate of the composites reduced since the epoxy was reinforced with bamboo fibres. Scanning electron microscopy analysis showed different wear mechanisms and damages.

Menstrual hygiene practices among adolescent girls in rural area of India

Menstruation and menstrual practices still face many social, cultural, and non secular restrictions which is an enormous barrier within the path of menstrual hygiene management. In many parts of the country especially in rural areas girls aren't prepared and aware of menstruation in order that they face many difficulties and challenges reception, schools, and work places. In rural areas, women don't have access to sanitary products or they know little about the kinds and method of using them or are unable to afford such products due to high cost. So, they mostly believe reusable cloth pads which they wash and use again. Implementation of recent techniques like incineration can help to scale back the waste. Also, awareness should be created to stress the utilization of reusable sanitary products or the natural sanitary products made up of materials like banana fibre, bamboo fibre, sea sponges, water hyacinth, and so on.

Development of Non-Woven Fabrics from Bamboo/Polypropylene Fibres and its Application in Personal Protective Equipment-A Review.

The important component of personal protective equipment is a mask. Mask is more important in a pandemic because it safeguards our life by stopping the spreading of the Coronavirus by entrapping the droplets from the corona affected person to enter into the wearer’s nose. Many types of masks are available such as non-woven mask, reusable mask, N95 mask and cloth mask etc. The majority of commercial masks are non-woven masks which are made up of polypropylene fibre. The main drawback of non-woven masks is their discomfort due to lack of breathability. This problem is solved by utilizing natural fibres as one of the raw material in non-woven and using them in the mask. Bamboo fibre is a natural celluloid fibre having good comfort properties with antimicrobial properties. Hence an attempt is made in this review article to examine the important properties of bamboo fibre and to evaluate its potential as a protective barrier material in non-woven face masks.

Development of bamboo polymer composites with improved impact resistance

Reinforcing thermoplastic polymers with natural fibres tends to improve tensile and flexural strength but adversely affect elongation and impact strength. This limits the application of such composites where toughness is a major criterion. In the present work, bamboo fibre reinforced polypropylene (PP) composites were prepared with bamboo fibre content varying from 30% to 50% with improved impact resistance. Homopolymer and copolymer PP were used as the matrix polymer and an elastomer was used (10% by wt.) as an additive in the formulation. Copolymer based composites exhibited superior elongation and impact strength as compared to homopolymer based composites. The adverse impact of elastomer on tensile and flexural strength was more pronounced in homopolymer based composites. The study suggested that the properties of the bamboo composites can be tailored to suit different applications by varying reinforcement and elastomer percentage.

Characterization and structural properties of bamboo fibre solid foams

In this work, cellulose fibres extracted from bamboo culms were used to fabricate two types of cellular materials: rigid foams and fibrous networks. A relatively simple and low-technology fabrication method is presented, using natural binders and blowing agents to manufacture rigid foams, and fibrillation by partial hydrolysis in H2SO4 to manufacture fibrous networks. The compressive response is related to the internal microstructure and processing parameters. In the case of fibrous networks, the achievable relative density range is determined by the length of initial fibres and extent of external fibrillation. The compressive properties are dictated both by the density of the network and strength of the fibrous bridges, showing a linear stiffness-density relationship due to the length of fibres, and an inverse relationship at increased external fibrillation. The rigid foams showed an orthotropic internal microstructure but nearly isotropic compressive response, due to the influence of the interpenetrating void structure on the deformation and fracture mechanisms. The results show the potential of bamboo-fibre porous materials as low cost, lightweight structural materials.
