  • A Perspective on High-Performance CNT Fibres for Structural Composites
    A Perspective on High-performance CNT fibres for Structural Composites Anastasiia Mikhalchan, Juan José Vilatela IMDEA Materials Institute, C/Eric Kandel 2, Getafe, Madrid, Spain, 28906 This review summarizes progress on structural composites with carbon nanotube (CNT) fibres. It starts by analyzing their development towards a macroscopic ensemble of elongated and aligned crystalline domains alongside the evolution of the structure of traditional high- performance fibres. Literature on tensile properties suggests that there are two emerging grades: highly aligned fibres spun from liquid crystalline solutions, with high modulus (160 GPa/SG) and strength (1.6 GPa/SG), and spun from aerogels of ultra-long nanotubes, combining high strength and fracture energy (up to 100J/g). The fabrication of large unidirectional fabrics with similar properties as the fibres is presently a challenge, which CNT alignment remaining a key factor. A promising approach is to produce fabrics directly from aerogel filaments without having to densify and handle individual CNT fibres. Structural composites of CNT fibres have reached longitudinal properties of about 1 GPa strength and 140 GPa modulus, however, on relatively small samples. In general, there is need to demonstrate fabrication of large CNT fibre laminate composites using standard fabrication routes and to study longitudinal and transverse mechanical properties in tension and compression. Complementary areas of development are interlaminar reinforcement Corresponding Author. E-mail: [email protected] (Anastasiia Mikhalchan) Corresponding Author.

  • Temperature and Humidity Aging of Poly(P-Phenylene-2,6

The objectives of this study were to expose woven PBO body armor panels to elevated tem- perature and moisture, and to analyze the chemical, morphological and mechanical changes in PBO yarns extracted from the panels. A 30% decrease in yarn tensile strength, which was correlated to changes in the infrared peak absorbance of key functional groups in the PBO structure, was observed during the 26 week elevated temperature/elevated moisture aging period. Substantial changes in chemical structure were observed via infrared spectroscopy, as well as changes in polymer morphology using microscopy and neutron scattering. When the panels were removed to an ultra-dry environment for storage for 47 weeks, no further decreases in tensile strength degradation were observed. In a follow-on study, fibers were sealed in argon-filled glass tubes and exposed to elevated temperature; less than a 4% decrease in tensile strength was observed after 30 weeks, demonstrating that moisture is a key factor in the degradation of these fibers.

Although the mechanical properties are documented for these fibers at ambient and elevated temperatures, there is an absence of data in the open literature for how these fibers behave at very low temperatures. To evaluate the mechanical properties, the ASTM standard method for testing at ambient temperature was used as a baseline. The low temperature tests were conducted inside a double walled cryogenic chamber to evaluate the fiber performance at 100K.

(August 2006) Joseph M. O’Neil, B.S., Texas A&M University Chair of Advisory Committee: Dr. Roger J. Morgan The moisture absorption behavior of Zylon fibers was characterized in various high temperature and high humidity conditions in a controlled environment. The results of these thermal cycling tests show that PBO fibers not only absorb, but also retain moisture (approximately 0.5-3%) when exposed to elevated temperature and humidity cycles. Also, the impurities of Zylon fibers were characterized through the use of Laser Ablation Inductively Coupled Plasma Mass Spectrometry (LA-ICP-MS) and solid state Nuclear Magnetic Resonance (NMR). These tests demonstrated that, in addition to other impurities, PBO fibers may contain up to 0.55 weight percent phosphorus, and that this phosphorus is present in the form of phosphoric acid.

Some of these unique properties were discovered through 20 years of research and development of the polymer Vectra®. Celanese committed to developing a thermotropic (melt processable) LCP in the mid 1970’s and commercialized the Vectra family of resins in 1985. The molecules of the liquid crystal polymer are rigid and position themselves into randomly oriented domains.The polymer exhibits anisotropic behavior in the melt state, thus the term “liquid crystal polymer.” Upon extrusion of the molten polymer through small spinnerette holes, the molecular domains align parallel to each other along the fiber axis.The highly oriented fiber structure results in high tensile properties. A schematic diagram of the molecular chain structure is shown in Figure 1. Figure 1: Schematic Of Molecular Chain Structure Of Fiber Conventional Liquid Crystal The attributes of Vectra, such as excellent Polyester Polymer mechanical properties, property retention over a wide range of temperatures, excellent chemical resistance, and low moisture pick-up, carry Melt Spinning Melt And Spinning over to the fiber.The fiber also exhibits no Heat Drawing measurable creep when loaded up to 50% of the threadline breaking load.

  • Ballistic Impact Response of Kevlar 49 and Zylon Under Conditions Representing Jet Engine Fan Containment
    Ballistic Impact Response of Kevlar 49 and Zylon Under Conditions Representing Jet Engine Fan Containment J. Michael Pereira and Duane M. Revilock NASA Glenn Research Center, Cleveland, Ohio [email protected] [email protected] Abstract A ballistic impact test program was conducted to provide validation data for the development of numerical models of blade out events in fabric containment systems. The impact response of two different fiber materials - Kevlar 49 (E.I. DuPont Nemours and Company) and Zylon AS (Toyobo Co., Ltd.) was studied by firing metal projectiles into dry woven fabric specimens using a gas gun. The shape, mass, orientation and velocity of the projectile were varied and recorded. In most cases the tests were designed such that the projectile would perforate the specimen, allowing measurement of the energy absorbed by the fabric. The results for both Zylon and Kevlar presented here represent a useful set of data for the purposes of establishing and validating numerical models for predicting the response of fabrics under conditions simulating those of a jet engine blade release situation. In addition some useful empirical observations were made regarding the effects of projectile orientation and the relative performance of the different materials. Introduction In the last thirty years the use of aramid fabrics in jet engine blade containment systems has become common. It is recognized that high strength and high elongation fabrics, combined with innovative structural concepts can provide a light weight, effective fan case system that provides the strength required to safely handle impact loads, blade rub loads and the large dynamic loads caused by rotor imbalance.

They gain new importance in technical applications, and man-made fibers are at the center of this ongoing innovation. The development of high-tech textiles relies on enhancements of fiber raw materials and processing techniques. Today, melt spinning of polymers is the most commonly used method for manufacturing commercial fibers, due to the simplicity of the production line, high spinning velocities, low production cost and environmental friendliness. Topics covered in this review are established and novel polymers, additives and processes used in melt spinning. In addition, fundamental questions regarding fiber morphologies, structure-property relationships, as well as flow and draw instabilities are addressed. Multicomponent melt-spinning, where several functionalities can be combined in one fiber, is also discussed.
