Abstract: The objective of this work was to use a novel 3-D test analysis system for evaluating the mechanical properties of the natural fiber fabric composites under biaxial loads.

In wet condition, strength of ramie fibers is increased. It has resistance to heat, light, acid and alkali etc. The statements, opinions and data contained in the journals are solely Ramie (Boehmeria nivea), commonly known as China grass, white ramie, green ramie and rhea, is one of the group referred to as the bast fiber crops. Ramie fiber reported to exhibit good mechanical properties such as tensile strength (400–938 MPa), modulus elasticity (61–128 GPa) with 1.2%–3.8% elongation [ 30, 31] and was successfully utilized as reinforcement in polymer composites [ 32 – 35 ]. Composite Structures, 2007. You seem to have javascript disabled. Ramie can be spun but also used for needle and wet felting. 37(9): pp.1316-1324. 41(1): pp.16-21. 48: pp.51-58. Article Preview. Bleaching could be done with ramie fiber … Ramie fibres were surface treated in order to enhance the interfacial interaction between ramie natural fibres and vinyl resin matrix. Composites Science and Technology, 2012. Dyeing could be done easily. It resists the attack of bacteria, mildew and other insects. Some or all are needed to separate the raw fiber from the adhesive gums or resins. [8] Ramie fibers have similar properties to other commercial bast fibers [3,4]. Herein, the bio-based epoxy composites were reinforced with ramie fibre (RF) and recycled carbon fibre (rCF) via inter-layer hybridisation. Dhakal, H.N., et al., The low velocity impact response of non-woven hemp fibre reinforced unsaturated polyester composites. The properties of the fabric include: It doesn’t shrink when washed. Composites Part A: Applied Science and Manufacturing, 2006. Our dedicated information section provides allows you to learn more about MDPI. The fibres are exposed to three different treatment ways in this paper. During laundering, it withstands with water temperature. However, other reports claim that the tensile strengths of cotton, flax, hemp and ramie are similar. Scida, D., et al., Influence of hygrothermal ageing on the damage mechanisms of flax-fibre reinforced epoxy composite. 557: pp.17-28. It is reported that their tensile strength is eight times greater than that of cotton, and seven times greater than that of silk. Composites Part A: Applied Science and Manufacturing, 2010. Properties for these fibers include excellent tensile strength and modulus, high durability, low bulk density, good moldability, and recyclability. However, its utilization in automotive friction composite materials was barely reported. The fibres are exposed to three different treatment ways in this paper. The fiber's extraction and cleaning are expensive, chiefly because of the several steps—involving scraping, pounding, heating, washing, or exposure to chemicals. There is also growing interest in other uses of the fibers, such as in composite materials [2]. The surface topography and binding force influenced by the treatments were characterized by contact angle and mechanical property. Greater utilization o… Lyocell fiber can absorb around 20% of its own weight in moisture. The physical properties of Ramie fibre exhibited high tenacity, high luster and brightness. It is a very elastic fiber and has a good resistance to twisting. Find support for a specific problem on the support section of our website. Properties. Materials & Design, 2013. Composition of ramie hemicelluloses and effect of polysaccharides on fiber properties - Zhengfan Li, Zhaoling Li, Ruoyao Ding, Chongwen Yu, 2016 43: pp.177-184. As ramie fibre is essentially composed of pure cellulose22.32 , the processed fibre was subjected (0 IR study and the spectrum so obtained was compared with that of pure cellulose. Mechanical properties of the biocomposite were [2] [10] Composites Part B: Engineering, 2013. While linen and hemp harvesting rely on the microbial retting (degradation) of pectins, ramie is normally extracted by decorticating fresh stems to produce bark ribbons that are subsequently dried, scraped, and de-gummed. Materials & Design, 2013. Xianghua Liu, Kaifeng Zhang and Mingzhe Li, https://doi.org/10.4028/www.scientific.net/AMR.712-715.203. Ramie is one kind of natural fiber. Baley, C., et al., Influence of chemical treatments on surface properties and adhesion of flax fibre–polyester resin. 37(10): pp.1626-1637. Ramie fiber is very durable, is pure white in colour and has a silky luster. ADVANTAGES OF RAMIE AS A FABRIC resistant to bacteria, mildew, alkalis, rotting, light and insect attacks extremely absorbent and therefore comfortable to wear, especially during warm weather has … Monteiro, S.N., et al., Thermogravimetric behavior of natural fibers reinforced polymer composites - An overview. However, other reports claim that the tensile strengths of cotton, flax, hemp and ramie are similar. To make the fabric more resistant and shinier, it is often mixed with other fibers (natural or synthetic), such as cotton, hemp, wool, and viscose. Yousif, B.F., et al., Flexural properties of treated and untreated kenaf/epoxy composites. [6] Help us to further improve by taking part in this short 5 minute survey, Effect of Polypropylene Fibers on Self-Healing and Dynamic Modulus of Elasticity Recovery of Fiber Reinforced Concrete, Influence of Stem Diameter on Fiber Diameter and the Mechanical Properties of Technical Flax Fibers from Linseed Flax, Interfacial Characterization by Pull-Out Test of Bamboo Fibers Embedded in Poly(Lactic Acid). Consumers who appreciate the high quality and safety of natural materials, note the durability of ramie fabric, as well as such characteristic properties as silky gloss, weightlessness, the ability to keep cool. Yu, T., et al., Effect of fiber surface-treatments on the properties of poly(lactic acid)/ramie composites. Ramie fibers are very long and fine, have a natural shine and are very strong, even when they are wet. Examples of bast fibers include hemp, jute, flax, ramie, and kenaf. After three layers of the fibers were wetted, the mould was heated at 180 C for 15 minutes and then pressed at 40 MPa.

Vázquez, Study of saturated and unsaturated permeability in natural fiber fabrics. matlac matrix was painted to the plain weaver of ramie fibers. Materials Science and Engineering: A, 2012. We immobilized Agrobacterium larrymoorei A1, a potent extra-cellular cellulase producing bacteria, in Ca-alginate.
