The pneumatic tyre is a complex structure which performs a variety of functions essential to the effective operation of most vehicles. The performance of a tyre can be considered in terms of a b257 of criteria; durability, tread wear, noise, energy consumption (rolling resistance), vibrations and traction. In this report the authors review recent advances in all these areas. An additional indexed section containing several hundred abstracts from the Rapra Polymer Library database gives useful references for further reading.

This book highlights the mechanics of tire performance, offering detailed explanations of deriving basic equations for the fundamental properties of tires, and discussing ways to improve tire performance using these equations. It also compares the theory with practical measurements. The book commences with composite mechanics, which is the fundamental theory for belt and carcass tires, and covers classical, modified and discrete lamination theory. It then addresses the theory of tire shape and spring properties and the mechanics of tread pattern contact properties, as was well as the performance of various tires. This comprehensive book is a valuable resource for engineers involved in tire design and offers unique insights and examples of improvement of tire performances.

This is an overview of the factors tyre compounders and engineers must consider when developing compounds for tyres. It discusses compounding ingredients for tyre rubbers by class including polymer types. The future of tyres in vehicles is also outlined. An additional indexed section containing several hundred abstracts from the Polymer Library provides useful references for further reading.

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.

This review discusses the preparation of highly ordered polyacetylene blends and compares forms of polyacetylene obtained by different methodsand includes an analysis of the formation of defects in polyacetylene during growth of the polyene chain and cis-trans isomerisation. The mechanism of acetylene polymerisation with rhenium catalysts, and the reactivity of highly ordered polyacetylene blends to oxidation and doping are also discussed. An additional indexed section containing several hundred abstracts from the Rapra Polymer Library database gives useful references for further reading.
