Mechanical Properties of Unidirectional Epoxy Matrix Composites Reinforced with Scutched Flax and Tow By-Product
ECCM16 - 16TH EUROPEAN CONFERENCE ON COMPOSITE MATERIALS, Seville, Spain, 22-26 June 2014 MECHANICAL PROPERTIES OF UNIDIRECTIONAL EPOXY MATRIX COMPOSITES REINFORCED WITH SCUTCHED FLAX AND TOW BY-PRODUCT N. Martina*,c, P. Daviesb, C. Baleya aLIMATB, EA 4250, Univ. Bretagne-Sud, 56100 Lorient, France bMarine Structures Laboratory, IFREMER, 29280 Plouzané, France cVan Robaeys Frères, 83 rue Saint-Michel, 59122 Killem, France *[email protected] Keywords: Flax fibers, Scutching, Flax by-products, Composite materials Abstract The decortication of flax by scutching yields scutched flax and tows. In this study, we have compared the properties of composite materials made of scutched flax and flax tows from the same batch. A series of unidirectional epoxy composites were manufactured by wet moulding. Mechanical properties of single fibers and composite materials were measured by tensile tests. The tensile properties of single fibers were in the same range. The tensile properties of the unidirectional composites show a similar evolution of properties versus fiber volume fraction. The results show that tows could be used to reinforce high performance composite materials. 1. Introduction A wide range of plant fibers have been studied for composite reinforcement including hemp, jute, sisal and flax [1]. Among them, flax fibers have excellent specific mechanical properties and are being evaluated as a replacement for E-glass fibers [2,3]. Flax (Linum usitatissimum) is the major plant fiber cultivated in northern Europe, mainly for the textile sector. The structure and composition of flax plants is complex [4,5]. The stems contain fiber bundles embedded in cortex tissues at the periphery. In these bundles, single fibers are grouped together by middle lamellae. -

Raffia Palm Fibre, Composite, Ortho Unsaturated Polyester, Alkali Treatment
American Journal of Polymer Science 2014, 4(4): 117-121 DOI: 10.5923/j.ajps.20140404.03 The Effect of Alkali Treatment on the Tensile Behaviour and Hardness of Raffia Palm Fibre Reinforced Composites D. C. Anike1,*, T. U. Onuegbu1, I. M. Ogbu2, I. O. Alaekwe1 1Department of Pure and Industrial Chemistry, Nnamdi Azikiwe University Awka, Anambra State, Nigeria 2Department of Chemistry Federal University Ndufu-Alike, Ikwo Ebonyi State, Nigeria Abstract The effects of alkali treatment and fibre loads on the properties of raffia palm fibre polyester composite were studied. Some clean raffia palm fibres were treated with 10% NaOH, and ground. The ground treated and untreated fibres were incorporated into the ortho unsaturated polyester resin. The treated and the untreated fibre composites samples were subjected to tensile tests according to ASTM D638 using instron model 3369. The microhardness test was done by forcing a diamond cone indenter into the surface of the hard specimen, to create an indentation. The significant findings of the results showed that alkali treatment improved the microhardness and extension at break at all fibre loads, better than the untreated fibre composites, with the highest values at 20% (14.40 and 3.47mm for microhardness and extension at break respectively). Tensile strength, tensile strain and modulus of elasticity also improved for alkali treated fibre composites, except in 5% and 20% for tensile strength, 15% for tensile strain, and 15% and 20% for modulus of elasticity, compared to the corresponding fibre loads of untreated fibre composites. Keywords Raffia palm fibre, Composite, Ortho unsaturated polyester, Alkali treatment The main drawbacks of such composites are their water 1. -

Flax and Linen: an Uncertain Oregon Industry by Steve M
Flax and Linen: An Uncertain Oregon Industry By Steve M. Wyatt One of the several painstaking, time-consuming tasks involved in processing flax is shown in this photo from 1946. Here workers bind dried bundles of retted flax, preparing them for scutching, the procedure by which usable fiber is separated from the plant. (Courtesy Horner Museum, Oregon State University) In many languages the word for flax is lin. In Eng lish, then, the two principal products derived from Steve m.

Spinning and Weaving of Flax and Wool
The Museum | The Village Hall | The Research Library | The Museum Shop Spinning and Weaving of Flax and Wool 1 – Flax Plant Linen is made from a plant called flax. The plants were usually harvested in August. The plants were laid out to dry in the sun and then the seed pods were pulled off. The stalks were bound into bundles and soaked in a stream or pond for several days. Then the fibers were taken from the plant, combed and spun into thread on a spinning wheel. Then the thread was woven into cloth. 2 – Wool Wool comes from sheep that were usually sheared in the spring. Men and older boys usually did this job. The wool was combed, washed and rubbed with grease then spun into thread on a spinning wheel and then woven into cloth. 3 – Carding Colonial women and children used cards to straighten out the curly wool of the sheep. A card consisted of a piece of wood with a handle and it had nails or needle like objects driven through the back to the front of the card. They would put in a handful of wool on a card and then use another card to comb the wool back and forth until it was as straight and soft as possible. The wool was then ready for the spinning wheel. 4 – Spinning Wheels Spinning wheels were used to turn the flax and wool fibers into thread. The larger of the spinning wheels is for wool and the small one is for flax. 5 – Loom came from the Pike Haven Foster house. -

ISSN: 2350-0328 International Journal of Advanced Research in Science, Engineering and Technology Vol. 2, Issue 10 , October 2015 Thermal Behaviour of Flax Kenaf Hybrid Natural Fiber Composite V.S. Srinivasan, S. Rajendra Boopathy, B. Vijaya Ramnath Department of Mechanical Engineering, CEGC, Anna University, Chennai-25. Department of Mechanical Engineering, CEGC, Anna University, Chennai-25. Department of Mechanical Engineering, Sri Sairam Engineering College, Chennai-44. ABSTRACT: In this work, natural fibers of flax and kenaf are used. Hybrid materials are given importance as they play very important role in all applications and characterizations. This paper deals with one of such hybrid composite made of natural fibers namely, kenaf and flax fibers. The hybrid built-up is such that one layer of kenaf is sandwiched between two layers of flax fibres by hand layup method with a volume fraction of 40% using Epoxy resin and HY951 hardener. Glass fiber reinforcement polymer (GFRP) is used for lamination on both sides. Thermal properties are investigated for single fiber composites and kenaf - flax with GFRP hybrid composites. The hybrid composites have better thermal stability than single fibre composites. KEYWORDS: Flax, Kenaf, GFRP, Thermal behavior 1. INTRODUCTION The usage of natural fiber- reinforced composite materials is rapidly growing both in industries and in various research activities. The advantages of fibers are cheap, recyclable and biodegradable. Plants such as flax, hemp, cotton sisal, kenaf, banana etc., are the most used reinforcements of composites. They are used widely for manufacturing composites because of their easy availability, renewability, low density, and low price. The natural fiber containing composites are more environmental friendly and are used in transportation (automobiles, railway coaches, aerospace etc.,), military applications, building and construction industries in paneling and partition boards, packaging, consumer products etc. -

They had a chiton, which probably involved a certain amount of real sewing, although most of the needlework done by Greek women was in the form of embroidery. The spinster continued to feed tow from the distaff into the growing length of yarn until the spindle reached the floor. The peplos was fastened at the shoulders, armhole openings were left on each side, and the peplos might or might not be cinched with a belt. Caron, Beaudouin. Moffett, Kenworth. Italian Peninsula, B.

Lazzarini, Lorenzo and Clemente Marconi. Greek and Roman Textiles and Dress Writer By merging the study of Greek religion and the study of textiles, the current study illustrates how textiles are, indeed, central materialisations of Greek cult, by reason of their capacity to accentuate and epitomize aspects of identity, spirituality, position in the religious system, by their forms as links between the maker, user, wearer, but also as key material agents in the performance of rituals and communication with the divine. -

The Textile Machinery Collection at the American Textile History Museum a Historic Mechanical Engineering Heritage Collection
THE TEXTILE MACHINERY COLLECTION AT THE AMERICAN TEXTILE HISTORY MUSEUM A HISTORIC MECHANICAL ENGINEERING HERITAGE COLLECTION Textiles are an important part of our everyday lives. They clothe and comfort us, protect our first-responders, Introduction filter the air in our automobiles, and form the core of the fuselage in our newest aircraft. We enjoy their bright colors, wrap up in their warmth, and seldom give a second thought to how they make bicycles stronger and lighter or how they might be used to repair our vital organs. As textiles have changed from the first simple twisted fibers to high-tech smart fabrics, the tools and machinery used to make them have evolved as well. Drop spindles and spinning wheels have given way to long lines of spinning frames. And looms now use puffs of air instead of the human hand to insert the weft thread in a growing length of fabric. During the eighteenth and nineteenth centuries, textile manufacture was the catalyst for the Industrial Revolution in America. It was the leading edge in the transformation from an agricultural to a manufacturing economy and started the move of significant numbers of people from rural areas to urban centers. With industrialization came a change in the way people worked. No longer controlled by natural rhythms, the workday demanded a life governed by the factory bell. On the consumer side, industrialization transformed textiles from one of a person’s most valuable possessions to a product widely available at incredibly low prices. For more than a century, textile mills in Great Britain and the United States dominated textile production and led the industrial revolution in both Europe and North America. -
