Mechanical Characterization of Biodegradable Linen Fiber CompositesIJMER
Abstract: The conventional materials like iron, mild steel, cast iron etc are having good mechanical properties. Hence they are widely used in structural engineering applications. These conventional materials have some defects like formation of rust, low weight to strength ratio, high production cost. To overcome these defects, engineers started fabricating composite materials. Composites exhibit peculiar properties like different strengths in different directions, rust resistant, high strength to weight ratio, but they pollute the environment. Now the natural fibre composites are widely used in automobile industry. The natural fibres and resins are used to fabricate an eco friendly composite material. Lack of resources and increasing environmental pollution has evoked great interest in the research of materials that are
friendly to our health and environment. Bio polymer composites fabricated from natural fibres is currently
the most promising area in polymer sciences. This is designed to assess the possibility of fibre as reinforcing material in composites. Epoxy resin was made a stiffened panel to conduct tensile test. In this paper it is aimed to explain all possible ways to use natural composites in automobile components. The main advantages of using natural fibers are their degradability and light weight. They are environment friendly and also increase the fuel economy

In present scenario natural fibers have received much attention because of their light weight, nonabrasive, combustible, nontoxic, low cost and biodegradable properties. Among the various natural fibers, banana fiber was focused for its pretreatment conditions for preparing perfect fiber. In previously many researchers have found various fibers have been pretreated and they obtain its properties and its applications. In this project banana fiber has been taken as natural fiber and it was pretreated and its properties after pretreatment were obtained. The pretreatment was alkali, sodium hydroxide, potassium permanganate treatment, and bleaching was carried out. Then the composite specimen boards were fabricated by various pretreatment banana fiber, polyethylene and matrix. It undergone to mechanical testing, tensile test, hardness test and also SEM analysis was carried out to check their microstructure. The perfect fiber was found by the obtained results from their properties and bonding nature.

This document discusses chemically treated coir fiber reinforced concrete. It begins with an abstract that outlines adding coir fiber to concrete to improve tensile and flexural properties in a sustainable way. It then describes the materials and methodology used. Coir fibers were chemically treated using a 1N sodium hydroxide solution for 2 hours before being dried and mixed into concrete at ratios of 0.1%, 0.2%, and 0.3% by weight of cement. Common tests on the cement, aggregates, and treated fiber concrete mixtures are discussed to evaluate properties like compressive strength.

The document provides information on how the Competition Act of 2002 impacts trade associations in India. It discusses how trade associations can violate the act through anticompetitive agreements or facilitating prohibited information exchanges between competitors. The Competition Commission of India has found some trade associations guilty of cartel-like behavior in the past, such as the film producers association engaging in boycotts and price fixing. Trade associations need to avoid facilitating discussions around prices, markets, bids, and exchanges of sensitive competitive information to stay compliant with the act.
This document summarizes the state of the Indian economy in 2012. It notes that global growth estimates have been revised downward. While the US and European economies have not fully recovered from recession, India's growth is projected to slow as well, impacted by weakness abroad. Exports from India are declining, particularly to Europe, ASEAN and Northeast Asia. Capital inflows to India have also been volatile, with FDI steadier than portfolio flows. The rupee has begun depreciating against the dollar after gaining strength earlier in 2012.
The document summarizes the current state of the Indian economy and key industries based on a presentation by the President of CRISIL Research. It finds that (1) domestic and global macroeconomic conditions remain weak, though recent reforms provide hope; (2) industry profit margins have stabilized after declining for several quarters; and (3) capital investments are expected to decline for the second straight year, especially among private sector companies, due to policy inaction on land acquisition, mining, and other issues according to a poll of companies.
This document summarizes bans and challenges facing the plastics industry in India from the perspective of Arvind Mehta, Chairman of the Plastivision India Advisory Board. [1] It provides background information on India's population, economy, and the diversity of its 28 states and 7 union territories. [2] It then shows that 15, 11, 10, and finally 3 states and union territories have imposed bans or restrictions on plastics, with each jurisdiction setting its own laws. [3] It concludes that long-term solutions require addressing awareness, the visible impacts of plastic waste, myths about plastic waste management, the role of recycling technologies and consumers, and incentives for reduction and efficient waste systems.
The document discusses threats and opportunities related to plastic waste management in India. It notes that plastic waste generation is increasing as plastic usage grows. Currently, only about 60% of plastic waste is collected and 40% remains uncollected. Improper waste management can cause various environmental and health problems. The recycling industry in India involves both organized large recyclers and many smaller informal recyclers and waste pickers. The document outlines various opportunities to improve waste management through better segregation, collection, recycling technologies, and use of plastic waste in applications like road construction and cement kilns.
6 outreach positive contributions of plasticsAIPMA
The document discusses strategies and opportunities for the plastics industry. It notes that plastics are often perceived negatively in terms of health, environment and waste management. However, plastics have positive contributions by reducing greenhouse gas emissions compared to alternatives. The plastics industry needs to promote its environmental and social responsibilities. Efforts are being made in India through organizations like ICPE to encourage sustainable plastic waste management and develop standards. Collaboration between stakeholders is important to ensure plastics are used without harming people or the environment.
This document summarizes threats and challenges related to chemicals in plastics for the Indian plastics industry. It notes that awareness of issues is growing slowly in India and references studies that found toxic chemicals like phthalates in children's toys and pesticide residues in bottled water sold in India. It also outlines regulations from the Bureau of Indian Standards regarding permitted chemicals and materials for plastic food packaging and containers. The document lists several toxic chemicals that can be found in various plastics and consumer products, like Bisphenol A, and notes there is limited awareness in India about associated health risks.
