electromagnetic shielding effectiveness of copper glass fiber Knitted Fabric reinforced polypropylene Composites
Composites Part A-applied Science and Manufacturing, 2000Co-Authors: K. B. ChengAbstract:The main objectives of this research work are to develop conductive Knitted Fabric Composite materials and to determine their electromagnetic shielding effectiveness (EMSE). Polypropylene is the matrix phase and glass fibers are the reinforcement phase of the Composite material. Copper wires are incorporated as conductive fillers to provide the electromagnetic shielding properties of the Composite material. The amount of copper in the Composite material is varied by changing the yarn composition, Fabric knit structure and stitch density. The EMSE of various Knitted Fabric Composites is measured in the frequency range of 300 kHz to 3 GHz. The variations of EMSE of Knitted Fabric Composites with Fabric structure, stitch density and yarn compositions are described. Suitability of conductive Knitted Fabric Composites for electromagnetic shielding applications is also discussed.

effect of cf gf fibre hybrid on impact properties of multi axial warp Knitted Fabric Composite materials
Composites Part A-applied Science and Manufacturing, 2009Co-Authors: Tomohiko Sugie, Asami Nakai, Hiroyuki HamadaAbstract:Abstract The multi-axial warp Knitted Fabric (MWK) is a useful reinforcement for Composite. Higher mechanical performance resulted from no crimp of the fibre bundle is achieved compared with the general textile Composites. For the fibre bundle of MWK, only one type of reinforcement fibre among glass, carbon fibre bundle, and so on has been selected. The mechanical properties and the cost of MWK Composite depend on the feature of the fibre bundle. In order to extend the applicability of Composite, the concept of “fibre hybrid Composite” was applied into the MWK Composite. Two kinds of fibre bundle; carbon and glass, were used in the 0/90 multi-axial warp Knitted Fabric. As the fibre hybrid Composite; the inter-layer hybrid Composite in which each layer was Fabricated by carbon and glass fibre bundle respectively was investigated. Impact properties of Composite were investigated by using drop weight impact tests. In case of unsaturated polyester, total energy and progressive energy of inter-layer fibre hybrid Composite realized the highest value in all specimens. However, in case of epoxy resin, inter-layer hybrid Composite didn’t realize the highest value in all specimens. The difference in energy absorption capability could be described with the fracture mechanism.

Modeling the Tensile Behavior of Milano Rib Knit Fabric Composites
2016Co-Authors: Zheng-ming Huang, S. Ramakrishna, K. H. LeongAbstract:ABSTRACT: The mechanical properties of Milano rib knit Fabric reinforced Composites have been previously characterized [1–5]. The purpose of this paper is to theoretically pre-dict the stiffness and tensile strength of these Composites. Attention has been focused on simplicity and user-friendliness. The complicated Milano rib knit Fabric structure has been approximated by several simpler plain stitches, for which an analytical geometric model is applicable. After discretizing the representative volume element of the Milano Fabric com-posite into sub-elements which contain only straight yarn segments, the overall stiffness and strength of the Composite are obtained by assembling the contributions of a number of unidirectional fibrous Composites. A recently developed micromechanics model, the bridging model [6], is applied to estimate the stiffness and strength of each unidirectional Composite. The predicted stiffness and strength of the Milano Fabric Composites have been compared with the available experimental results. Reasonably good correlation has been found between the predictions and the experiments.
