Fiber Structure - an overview | ScienceDirect Topics
网页A fiber structure (X, p, b) is called a fiber space (or fibration) for the class A if for each Y in A, each continuous map f:Y × {0} → X, and each homotopy ϕ: Y × I → B of p ∘ f, there exists a homotopy φ ˜ of f covering ϕ.
Fiber - Wikipedia
网页Fiber or fibre (British English; from Latin: fibra [1]) is a natural or artificial substance that is significantly longer than it is wide. [2] Fibers are often used in the manufacture of other materials. The strongest engineering materials often incorporate fibers, for example carbon fiber and ultra-high-molecular-weight polyethylene.
Internal Structure of Fibers - SpringerLink
网页2023年1月10日 · This chapter deals with the internal structure of synthetic and cellulosic fibers. It differs fundamentally from the structure of inorganic fibers (e.g. glass) and metal fibers. Their structures are considered separately in the corresponding chapters.
Fiber Optics: Understanding the Basics - Photonics
网页An optical fiber consists of three basic concentric elements: the core, the cladding, and the outer coating (Figure 1). The core is usually made of glass or plastic, although other materials are sometimes used, depending on the transmission spectrum desired. The core is the light-transmitting portion of the fiber.
Introduction: The structure of fibres | SpringerLink
网页Abstract. The specific chemistry of a given type of fibre is undeniably crucial in determining many features associated with its processing, performance and end-uses; but it may also be asserted that its physical structure — i.e. the organisation and geometrical arrangement of its component parts —is at least equal in importance. This ...

Introduction to the science of fibers - ScienceDirect
网页2018年1月1日 · The science of fibers is multidisciplinary as it encompasses botany, zoology, organic chemistry, the physics of materials, and all of material science from polymers to ceramics. Fibers are ubiquitous and can be found all around us, not only in clothes but also in our very makeup.
Dietary fiber - Wikipedia
网页Dietary fiber (fibre in Commonwealth English) or roughage is the portion of plant-derived food that cannot be completely broken down by human digestive enzymes. [1] Dietary fibers are diverse in chemical composition and can be grouped generally by their solubility, viscosity and fermentability which affect how fibers are processed in the body. [2]
Man-made fibre - Chemical Composition, Molecular Structure
网页Man-made fibre - Chemical Composition, Molecular Structure: One of the features common to all the fibre-forming polymers is a linear structure. As explained in the article industrial polymers, chemistry of, polymers are built up by the joining together, through strong covalent bonds, of smaller molecular units known as monomers.
