RFL 浸胶和橡胶的粘合机理 ADHESION OF RFL-TREATED CORDS TO RUBBER NEW INSIGHTS INTO INTERFACIAL PHENOMENA RFL浸胶帘线与橡胶的粘合 对粘合界面的必威体育精装版认识 Chapter 1 Introduction: cord-rubber composites A brief introduction is given about the importance of cord-rubber composites. The example of a car-tyre shows that the cords carry all the loads that a tyre is subjected to; this is illustrated by a comparison between bias and radial tyres. The adhesion between cords and rubber is very important with regard to safety as well as durability of tyres. In this chapter, the objective of the project is defined and a description of the setup of the thesis is outlined. 第一章 简介 帘线-橡胶的复合体 本节简单介绍了帘线-橡胶复合体的重要性：比如，汽车轮胎，帘线承载轮胎的所有负荷，帘线与橡胶之间的粘合力对轮胎的使用寿命、安全性能非常重要，本章将简述项目的目标和本论文的结构。 1.1 INTRODUCTION 引言 Cord-rubber composites can be found in every day life. Examples of applications are car- and bicycle tyres, high-pressure hoses and conveyor belts. Some essential under-the-hood applications are made of cord-rubber composites as well: timing belts, V-belts and radiator hoses are examples. By far the largest of all these examples is the car tyre. The application of cords in tyres is essential because the cords prevent large deformations of the rubber material when excessive forces are applied. These forces are caused by the air pressure of the tyre, and by accelerating, breaking and cornering of the car. The network of cords that provides the tyre with its strength and its shape is called the carcass. There are two types of carcass constructions in use, thereby dividing virtually all tyres in two categories: radial and bias tyres, Figure 1.1.1 帘线和橡胶的复合体在日常生活中到处可见，比如汽车和自行车轮胎、高压胶管和橡胶输送带，包括汽车发动机室用的重要同步带、V带和散热水管等等。目前应用最大的就是汽车轮胎。在轮胎转向、加速、刹车时，轮胎会出现受力过大的情况，轮胎中的帘线可以避免轮胎中橡胶因受力增大出现大幅度变形。帘线的网状结构，给轮胎提供了强度以及外形。根据轮胎的骨架结构，轮胎分为两大类：斜交轮胎和织物轮胎。见图1.1.1 1.1.1 Bias tyre construction 斜交轮胎 The oldest tyre construction is called bias or cross ply: Figure 1.1A. A bias tyre has a casing which is made of stacked reinforcing layers
