Strength Properties of 3D Solid Orthogonal Panel Fabrics

IntroductionWith the development of high performance fiber andtextile perform manufacturing technology, fiber reinforcedcomposite materials are getting more and more attractivebecause they have many advantages such as their highstiffness and strength at low density, high specific energyabsorption behavior, and excellent fatigue performance.Therefore they are frequently used in a wide variety ofapplications[1], although most of them are two dimensional(2D) laminated comp…     

织物的动态传热传湿性能研究

文章探讨了织物的动态传热传湿性能,认为织物的传热和传湿是相互影响的,为此设计了一台织物的动态传热传湿性能测定仪,对织物在经历干燥—吸湿—放湿—干燥整个过程中所传导的热量(包括干热和湿热)进行了测量.根据测量得到的热流量曲线,本文提出了四个衡量织物动态传热传湿性能的指标,实验结果证明,所用指标能较好地反映织物的动态传导性能。结果表明,经织物所传递的热量大小与织物自身的传湿散热性能有关,湿阻小散热性能好的织物其测得的单位时间内传递的热量值较大.

THE EFFECT OF, ABRASION ON LOW STRESS MECHANICAL PROPERTIES OF FABRIC

The low stress mechanical properties of a pure wool and a wool / polyester blend twill fab-rics which were abraded at various abrasion cycles were measured using the KES-F system andthe Instron tensile machine. The surface change of fabrics before and after abrasion was stu-died by means of scanning electron microscope. With the increasing number of cycles, the re-covery behavior of the fabrics studied in tensile, shear and bending deformation decrease, theantibuckling ability lowers, the friction coefficient increases. The geometric roughness de-creases during the first step of abrasion then enhances with further abrasion. The influence ofabrasion on mechanical properties of the pure wool fabric are larger than that of blend fabric.
