Textile Fiber reinforced anionic polyamide 6 composites part i the vacuum infusion process
Composites Part A-applied Science and Manufacturing, 2009Co-Authors: K Van Rijswijk, Hen Bersee, Julie J E Teuwen, Adriaan BeukersAbstract:Abstract In order to manufacture thicker, larger and more integrated thermoplastic composite parts than currently can be achieved by melt processing, a vacuum infusion process is currently being developed at the Delft University of Technology using a reactive thermoplastic polymer called anionic polyamide-6 (APA-6). In previous studies it was demonstrated that the anionic polyamide-6 (APA-6) resin that is used has excellent mechanical properties. The present study assesses infused thermoplastic composites and focuses on Fiber-matrix interactions. Part I of this study focuses on the thermal effects, causes for deactivation of the initiator and the restriction caused by the low in-plane permeability of the Fiber Textiles on various transport phenomena. It will be shown that addition of pre-heated Fibers not only shortens the infusion window, but also influences the matrix properties by reducing the exothermic heat production. In addition, the low in-plane permeability of the Fiber Textiles influences the infusion time and causes the entrapment of voids. Finally, reactions between the matrix and the Fiber surface can lead to deactivation of the initiator and bond formation with the activator. Interfacial bonding, however, is discussed in more detail in Part II of this study, whereas the effect of adding a nucleating agent is discussed in Part III.

reactive processing of Textile Fiber reinforced thermoplastic composites an overview
Composites Part A-applied Science and Manufacturing, 2007Co-Authors: K. Van Rijswijk, Hen BerseeAbstract:Thermoplastic composites offer some interesting advantages over their thermoset counterparts like a higher toughness, faster manufacturing and their recyclable nature. Traditional melt processing, however, limits thermoplastic composite parts in size and thickness. As an alternative, reactive processing of Textile Fiber-reinforced thermoplastics is discussed in this paper: a low viscosity mono- or oligomeric precursor is used to impregnate the Fibers, followed by in situ polymerization. Processes that are currently associated to manufacturing of thermoset composites like resin transfer molding, vacuum infusion and resin film infusion, might be used for manufacturing of thermoplastic composite parts in near future. This paper gives an overview of engineering and high-performance plastic materials that are suitable for reactive processing and discusses fundamental differences between reactive processing of thermoplastic and thermoset resins.

Chapter 15 – Textile Fibers
Fundamentals of Forensic Science, 2015Co-Authors: Max M. HouckAbstract:Fibers make good evidence for a number of reasons: They vary greatly, are easy to analyze, and are everywhere present as Textiles. Fibers have figured prominently in many high-profile cases and are researched extensively by forensic and Textile scientists alike. Textile Fibers are among the most frequently encountered types of physical evidence. Color is one of the most underutilized traits of a Textile Fiber; the color of Fibers should be analyzed spectrally or chemically in any positive association. The combinations of characteristics make Fibers very specific evidence: It is rare to find two Fibers at random that exhibit the same characteristics.

The use of spectroscopy for Textile Fiber identification
Identification of Textile Fibers, 2009Co-Authors: Max M. HouckAbstract:Abstract: The use of spectroscopy for Fiber analysis is widespread and ranges from simple identification of polymer type(s) to structural information. Colorants used on Textiles, be they dyes or pigments, are also the subject of spectroscopic analysis. Of necessity, the spectroscopy of Fibers and related materials is a broad and complicated topic. This chapter will be limited, therefore, to basic concepts, applications, and future improvements in some of the spectroscopic analysis of Textile Fibers.

Introduction to Textile Fiber identification
Identification of Textile Fibers, 2009Co-Authors: Max M. HouckAbstract:Abstract: The identification of Fibers is critical to a number of industries, including Textiles, forensic science, fashion, and design. The actual identification, however, varies with industry and method. Changes in Textile technology create a constant need to improve identification methodology. The old methods – despite the increased pace of new technology – are often the best. Microscopy still dominates the field for analytical methods and provides a range of analysis barely possible with any other method. Combined with spectroscopy, microscopy is the quintessential Fiber identification tool.
