Download or read book Rubber Product Failure written by Roger P. Brown and published by iSmithers Rapra Publishing. This book was released on 2002 with total page 118 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rubber components are used in many demanding applications, from tyres and seals to gloves and medical devices, and failure can be catastrophic. This review of Rubber Product Failure outlines and illustrates the common causes of failure, while addressing ways of avoiding it. There has been increasing pressure to improve performance so that rubbers can be used at higher temperatures and in harsher environments. For example, the under-the-bonnet temperature has increased in some vehicles and new medical devices require longer lifetimes in potentially degrading biological fluids. The expectations of tyre performance in particular are increasing, and retreads have been in the spotlight for failures. The definition of failure depends on the application. For example, a racing car engine seal that lasts for one race may be acceptable, but in a normal car a life span of 10 years is more reasonable. If appearance is critical as in surface coatings and paints, then discolouration is failure, whilst in seals leakage is not acceptable. Each rubber product must be fit for the use specified by the consumer. Failure analysis is critical to product improvement. the cause of the problem can be much harder to find. It can range from a design fault to poor material selection, to processing problems, to manufacturing errors such as poor dimensional tolerances, to poor installation, product abuse and unexpected service conditions. The rubber technologist must become a detective, gathering evidence, understanding the material type and using deductive reasoning. Testing and analysis of failed materials and components add to the information available for failure analysis. For example, stored aged tyres appeared superficially to be alright for use, but on drum testing small cracks grew more quickly than in new tyres leading to rapid failure in service. Quality control procedures such as product inspection, testing and material quality checks can help to reach 100 percent reliability. In critical applications such as electricians' gloves for high voltage working, gloves are inspected before each use, while engine seals may be routinely replaced before the expected lifetime to avoid problems. in the literature is not high. However, several reviews have been written on specific products and references can be found at the end of this review. Around 400 abstracts from papers in the Polymer Library are included with an index. Subjects covered include tyre wear and failure, seals, engine components, rubber bonding failure, rubber failure due to chloramine in water, tank treads, gloves and condoms, medical devices and EPDM roofing membranes.

Download or read book Constitutive Models for Rubber IV written by Per-Erik Austrell and published by Routledge. This book was released on 2017-12-04 with total page 646 pages. Available in PDF, EPUB and Kindle. Book excerpt: The unique properties of elastomeric materials offer numerous advantages in many engineering applications. Elastomeric units are used as couplings or mountings between rigid components, for example in shock absorbers, vibration insulators, flexible joints, seals and suspensions, etc. However, the complicated nature of the behaviour of such material makes it difficult to accurately predict the performance of these units using finite element modelling, for example. It is imperative that constitutive models accurately capture relevant aspects of mechanical behaviour. The latest developments concerning constitutive modelling of rubber is collected in these Proceedings. Topics included in this volume are, Hyperelastic models, Strength, fracture & fatigue, Dynamic properties & the Fletcher-Gent effect, Micro-mechanical & statistical approaches, Stress softening, iscoelasticity, Filler reinforcement, and Tyres, fibre & cord reinforced rubber.
Download or read book Empire of Rubber written by Gregg Mitman and published by The New Press. This book was released on 2021-11-02 with total page 331 pages. Available in PDF, EPUB and Kindle. Book excerpt: An ambitious and shocking exposé of America’s hidden empire in Liberia, run by the storied Firestone corporation, and its long shadow In the early 1920s, Americans owned 80 percent of the world’s automobiles and consumed 75 percent of the world’s rubber. But only one percent of the world’s rubber grew under the U.S. flag, creating a bottleneck that hampered the nation’s explosive economic expansion. To solve its conundrum, the Firestone Tire and Rubber Company turned to a tiny West African nation, Liberia, founded in 1847 as a free Black republic. Empire of Rubber tells a sweeping story of capitalism, racial exploitation, and environmental devastation, as Firestone transformed Liberia into America’s rubber empire. Historian and filmmaker Gregg Mitman scoured remote archives to unearth a history of promises unfulfilled for the vast numbers of Liberians who toiled on rubber plantations built on taken land. Mitman reveals a history of racial segregation and medical experimentation that reflected Jim Crow America—on African soil. As Firestone reaped fortunes, wealth and power concentrated in the hands of a few elites, fostering widespread inequalities that fed unrest, rebellions and, eventually, civil war. A riveting narrative of ecology and disease, of commerce and science, and of racial politics and political maneuvering, Empire of Rubber uncovers the hidden story of a corporate empire whose tentacles reach into the present.

Download or read book Chemistry Was Their Life written by Marelene F. Rayner-Canham and published by Imperial College Press. This book was released on 2008 with total page 561 pages. Available in PDF, EPUB and Kindle. Book excerpt: British chemistry has traditionally been depicted as a solely male endeavour. However, this perspective is untrue: the allure of chemistry has attracted women since the earliest times. Despite the barriers placed in their path, women studied academic chemistry from the 1880s onwards and made interesting or significant contributions to their fields, yet they are virtually absent from historical records.Comprising a unique set of biographies of 141 of the 896 known women chemists from 1880 to 1949, this work attempts to address the imbalance by showcasing the determination of these women to survive and flourish in an environment dominated by men. Individual biographical accounts interspersed with contemporary quotes describe how women overcame the barriers of secondary and tertiary education, and of admission to professional societies. Although these women are lost to historical records, they are brought together here for the first time to show that a vibrant culture of female chemists did indeed exist in Britain during the late 19th and early 20th centuries.
