  • Deformability of a flax reinforcement for composite materials
    Switzerland, 2014
    Co-Authors: Vanleeuw A, Carvelli Valte, Lomov, Stepa Vladimirovitch, Arburski Marci, Van Vuure, Aa Willem
    Abstract:

    In this work, the deformability of a flax Fabric adopted as composite reinforcement is experimentally investigated. The Fabric (commercialized as FLAXPLY UD 180 by LINEO) is a quasi-unidirectional woven Fabric with thin weft yarns connecting thick slightly twisted warp using satin weave interlacing pattern. The study is dedicated to the understanding and measurement of the main deformation mechanisms occurring during forming processes. The deformation during extension is investigated under uniaxial and biaxial loading in the in-Plane tow directions (i.e. warp and weft). Particular attention is dedicated to the behavior during shear loading because this is considered the primary deformation mechanism in the reinforcement forming. Uniaxial bias extension and picture frame tests are adopted to measure the shear deformation. The tests are assisted by digital image correlation (DIC) technique to have a continuous measurement of the local deformation in the Fabric Plane during loading.status: publishe

  • investigation on static and dynamic mechanical properties of epoxy based woven Fabric glass carbon hybrid composite laminates
    Procedia Engineering, 2014
    Co-Authors: R Murugan, R Ramesh, K Padmanabhan
    Abstract:

    Abstract Balanced mechanical properties within the Fabric Plane and excellent formability have rendered the woven glass Fabric composite laminates popular in aircraft, automobile, marine and civil structures. In practice, while preferring glass woven Fabric layers in Fabrication, to achieve the required design strength, the nominal size of the component was increased. This increased the total weight of the component. In the present work, glass laminate is strengthened and stiffened by interplying high modulus carbon Fabric layers for attaining better specific properties. Two symmetrical four layered glass/carbon hybrid laminates and two dedicated four layered glass or carbon laminates were Fabricated separately using the hand lay up and compression moulding techniques. The static mechanical properties like tensile strength, flexural strength and impact strength and dynamic mechanical properties such as storage modulus, loss modulus and loss factor of these laminates were experimentally evaluated as per ASTM standards and reported. The influence of stacking sequence of composite laminates on static and dynamic mechanical properties was discussed in detail. The modulus curves of dedicated and hybrid composite laminates in a Cole-Cole plot show an imperfect semi-circular curve indicating the heterogeneity of the laminates and relatively good fibre/matrix bonding. A conclusion as to the superiority of one of the hybrid constructions for structural applications could also be reached.

  • transmission of ultraviolet light through reinforcement Fabrics and its effect on ultraviolet curing of composite laminates
    Polymer Composites, 2008
    Co-Authors: A Endruweit, Wout Ruijter, M S Johnson, A C Long
    Abstract:

    The ultraviolet transmission of various reinforcement textiles was quantified experimentally for the case of incidence of light normal on the Fabric Plane, and correlated with the curing behavior of laminates incorporating these Fabrics. For glass fiber Fabrics wetted with polyester resin, light is transmitted through the voids between the fiber bundles and through the fiber bundles. Multiscale modeling of the Fabric geometry allows the local transmission to be estimated and the average total transmission to be quantified. The results of curing experiments suggest that the degree of through-cure achieved after a given cure time is correlated to the Fabric transmission. Both are determined by the laminate thickness, the Fabric architecture and the fiber volume fraction, i.e., the fiber packing density. While the transmission is reduced by the presence of the reinforcement Fabrics, the total resin volume is reduced when compared with that of a resin only sample of the same thickness. A lower radiation dose is sufficient for curing, which partially compensates for the effect of reduced transmission. POLYM. COMPOS., 2008. © 2008 Society of Plastics Engineers
