To resist to dynamic loading and corrosive conditions, the fibers and the elastomer matrix must build up chemical bonds. This is achieved by treating textile fibers with an adhesion promoter in a separate processing step. Mechanical anchorage of the fiber is sufficient for products subjected to minor stress (low-pressure hoses, the typical ‘garden hose’). No […]

Fiber-reinforced rubber composites rely upon three systems: (i) reinforcement textiles; (ii) adhesive systems used to treat textiles to make them bondable to rubber; and (iii) rubber. 8.10.4.1 Reinforcement Fibers Inorganic fibers, organic fibers and metal fibers are well suited reinforcements for elastomer composites, and may be either threads or planelike structures. Filament yarn is used […]

The properties of elastomers make them very different from other materials, in particular with regards to entropy elasticity, viscoelasticity and chemical structure, which is a macro network. Due to a three-dimensional network, elastomers do not flow and are insoluble, but swellable. When the temperature increases, they will not melt until degradation occurs. Table 8.7 Fiber […]

Today, a modern medium-class vehicle contains around 250 kg of chemical materials, with plastics alone contributing 125 kg. Currently, approximately 900000 tons of polyurethanes are employed in automobile production, mainly in the manufacture ofseats, fenders and side fairings. Textiles and carpets provide comfort in the interior, while paints and underbody coatings provide an appealing appearance […]

In recent years, synthetic fibers have increasingly been used for products involving technical textiles. The technical advances resulting thereof directly or indirectly add to many domains of daily life without being recognized as ‘involving textiles’. Few people know, for example, that the safety and stability of dams, dyke reinforcements, roads, streets and freeways is achieved […]

The bonding of textiles is a key application in the manufacture and use of many products in virtually all domains of daily life. Examples are clothing (not only up-to — date fashion, but also functional and protective clothing), home textiles (carpets, wallpapers) and textile cleaning products (cleaning rags, extractor hood filters). The extent to which […]

8.10.1 The Early History of Fabric-Reinforced Rubber Materials Today, so much of the modern world relies upon articles made from polymer-textile (mainly rubber-textile) composites; in fact, it is difficult to imagine how we could survive without these goods in modern life. Products such as transportation systems (rubber-textile tires), material-handling systems (conveyor belts) and mechanical driving […]

Special types of steel are useful as structural materials for virtually all industrial production sectors owing to their particular material characteristics, especially their anti-corrosion properties. Historically, stainless steel has been used in the chemical and food industry, but it is also becoming popular in the building industry because their surfaces are metallically clean and visually […]

For securing or locking, joining and sealing in the manufacture of internal combus­tion engines, and in transmission manufacture, the use of anaerobic diacrylate-based adhesives is virtually self-evident today. Anaerobic adhesives remain liquid as long as they remain in contact with oxygen from the air (see Section 5.7). When a screw is tightened in a thread, […]

Painted and coated surfaces are bonded with high-performance adhesives. Many functional parts of domestic appliances are bonded; for example, the cooling coils at the back ofa refrigerator are bonded with heat-conducting adhesives, while the cover of a top-loading washing machine, which seals the drum, is bonded with polyure­thane adhesives [47]. Double-sided, high-performance adhesive tapes are […]
