Foreword
It is a great honor to write the Foreword to what will surely become a major contribution to the advance of glass science and engineering throughout the world—the publishing of a long overdue and modern summary of Fiberglass Science and Technology. The goals, scope, and expectations of this book are eloquently and thoroughly stated in the Preface authored by the internationally renowned Editor, Dr. Hong Li. That these objectives are met, and then some, is evidenced by the scholarly material presented in eight chapters by authors from across the globe, all of whom are similarly renowned and highly respected. Rather remarkably, over 1000 references are cited by these authors—a tremendous, timesaving treasure to those involved in the manufacture or scientific investigation of this material. The result of this collective effort is a summary of the latest science and technology on how fiberglass is fabricated, characterized, and utilized and the physical/chemical properties of this material resulting thereof. Of special value is the description offered of batch-to-melt processing—including environmental aspects—which is also undergirded by presentation of state-of-the-art modeling of rate phenomena associated with this process. In view of these remarks, it is confidently predicted that this book will come to be regarded as a milestone in the history of fiberglass and will be read and re-read by scientists, engineers, and educators involved in the manufacture or characterization of this material. Many may even come to regard it as the sine qua non of fiberglass technology. Thus, congratulations are offered to all involved in the writing and publication of this book.

Preface
Glass fiber, in both continuous form and discontinuous form, offers countless opportunities in people’s modern life, covering automobile and transportation, renewable energy, construction, chemical industry, electronics, consumer goods, etc. Glass fibers are used as reinforcements for organic matrices as an integral part of composites. Mineral wool fibers are used as a standalone material input for thermal insulation primarily in building materials. Driven by the global demand for cleaner environment, glass fiber with higher specific mechanical properties because of its light weight and unique high thermal insulation over metallic materials of the counterparts provides a wide range of solutions to meet the global call. Fiberglass industry has existed since the 1950s and has accelerated its production technology, capacity, and market applications since the 1990s. The research and development of fiberglass relies heavily on both inorganic and organic chemistries; the former delivers inherent properties for application and high-temperature processing needs and the latter provides the functionalities to bridge glass fiber product to plastic matrix of the composite and downstream process requirements in making the composite components. On the manufacturing technology site, fiberglass production requires a deep understanding of raw materials, energy, batch-to-melt conversion and glass fining, and fiber drawing. It also requires deep technical knowledge of glass volatilization in glass melting to meet emission control requirements. Combining our collective efforts from the pool of international expertise, this book covers relevant topics on fiberglass manufacturing, development and commercial application, fundamental glass science research, physics, fiberglass chemistry and sizing chemistry and usage, and spectroscopic techniques for materials characterization, including glass and glass fiber. The contributors of this monograph have combined decades of expertise and experiences in fiberglass and glass research and development, fiberglass manufacturing processes (operation, thermodynamics, etc.), glass and glass surface chemistry and molecular dynamics modeling of complex glass network structures, organic chemistry in designing fiberglass coating, i.e., sizing, and spectroscopic characterizations of glass and glass fibers, etc.

Overview
The first man-made glass by accident from melting natural sand with natron (natural sodium nitrate) can be dated around 3500 B.C. in Egypt and Eastern Mesopotamia. Numerous artifacts from archology excavations show pottery or glassware (fiancé) wrapped with man-made glass filaments or glass fibers. No specific historical records, but it is not unexpected that the first accidental discovery of making glass fibers coming from stretching a molten glass object. Knowing the glass making process, the early Egyptians would also learn the art making glass filaments or bigger glass fibers, perhaps found it naturally through the process of making glass objects, and subsequently wrap them over clay vessels and fuse glass fibers onto glass vessels for decoration. Venetian glass blowers in the sixteenth and seventeenth centuries used glass fibers to decorate elaborate glass articles. Glass fibers, in a fine textile form, were even used as fabric elements in fashion garments in the late nineteenth century, yet the business was not successful because of its breakage under repetitive folding, especially in washing. Today at least two major categories of glass fibers are industrialized, continuous glass fiber and mineral wool fibers. The former has become the most widely used and cost-effective reinforcing fibers. Early melt spun processes have evolved to today’s large-scale direct melt continuous fiber forming operations. Original E-Glass compositions for glass fibers have grown to include an increasing array of specialty glass

compositions that are targeted for key expanding markets in electronics, transportation, corrosion, construction, and in energy management. Prior to 2000, most major glass fibers manufacturers were concentrated in North America and Western Europe. Today, fiber glass production facilities are flourishing in China and beginning to spread to other regions of the world. It is the intent of this overview to provide insight into the technology that is associated with the continuing success of glass as a reinforcing fiber. Fiber glass technology associated with both material characteristics and manufacturing processes are described at a high level. The industrial mineral wool fiber has become the most widely used as glassy insulation material in which there are two branches, stone wool and glass wool. Mineral wool fibers are typically produced close to where the market demands the most. Traditionally stone wool fibers have been produced in Europe, whereas glass wool fibers typically are produced in North America, France, and the UK. As the need for insulation against cold and hot weather is growing, as well as protection against the spread of fire, the production facilities have moved toward the markets in the Middle East and Asia. In this chapter, these two major glass fiber categories are discussed, firstly continuous fibers and then industrial mineral wool fibers. For both categories their historical development, production process, glass chemistry and commercial status will be discussed as well as their various applications.
1.2
Continuous Glass Fibers
Two key developments around the mid-1930s create the means for glass fiber to become the base of a new industry of composite materials, i.e., organic polymers reinforced with glass fibers, more commonly known as glass fiber reinforced plastic composites (GFRPC). The first was improvement of the continuous glass wool fiber processing under the joint development between the Owens-Illinois Fiberglass Company and Corning Glass Works (now Corning Incorporated). In 1938, Owens Corning Fiberglass Corporation (OC) was established; during the same year, the continuous wool fiber process improvement led the development of continuous E-Glass fiber production. The second was the development of polymeric resin systems by DuPont in 1936 and others that could be combined readily with glass fibers. The GFRPC materials offer key material advantages over conventional metallic materials, including light weight, stiffness and strength, and resistance to corrosion and fatigue. Reinforcement glass fibers or fiberglass can be broadly divided into two categories—general purpose fibers and premium specialty fibers. General purpose glass fibers are known by the designation of E-glass with various compositions and are defined by specific oxide composition ranges according to the standard, ASTM D578 [1]. Historically, E-glass fibers have been predominant in the commercial production of fiber glass products for use as reinforcements in various industrial polymer-matrix composites applications. Other specialty glass fibers that have been

Continuous glass fibers for composite reinforcement have been categorized by the specific properties required for the end use applications as briefly discussed below. Figure 1.1 highlights the historical timeline of the fiber glass development and commercial use of these major glass fiber types in a chronological order. Tables 1.1 and 1.2 provide further detail on typical oxides and oxide ranges, physical and mechanical properties, and processing related properties. Specific examples of recent developments in the areas of D-, S-, and R-Glass are also included in these tables.
1.2.1
E-Glass
First commercialized in the late 1930s, E-Glass fiber is the most widely used class of fiber glass for GFRPCs [2, 3]. E-Glass is primarily a ternary system of CaO-Al2O3SiO2; B2O3 and F2 are conditionally used, varying between 0 and 10 weight % and 0 to 2 weight %, respectively. For much of its history, E-glass fiber production incorporates B2O3 in commercial compositions at levels of 7–8 weight %. This level provides an optimal balance of melting and fiber forming characteristics, mechanical properties, and electrical properties. Over time, however, increasingly restrictive environmental emission requirements for particulates have drove investment costs up for installation of emission control systems. Countries, such as Canada and Norway, have been leaders in the push to improve environmental conditions, leading to the introduction of the first boron-free commercial E-glass fiber production. The type of glass fiber has been also found to have excellent corrosion resistance under
