The fabric’s areal density was 121 g/m2, the warp and weft densities were 239 roots/10 cm and 246 roots/10 cm, respectively.

Ramie fiber-reinforced composites have been extensively used in many structural applications. Ramie is a plant fiber and produces a fabric that is very sustainable. Natural fibre, such as cotton fibre is free of impurities but only when no harmful pesticides or insecticides are used in its cultivation. 51409065), and the Fundamental Research Funds for the Central Universities. Processing. Ramie is one of the most important fiber resources and it needs the degumming process to produce fibers. These fibers are replacing metal wire as the transmission medium in high-speed, high-capacity communications systems that convert information into light, which is then transmitted via fiber optic cable. For comparison, the load-deformation curve predicted using the numerical and analytical methods, In this paper, a ramie fiber triangular structure was designed and optimized for the targeted high load-carrying capacity and light weight. Koronis et al. 2011 [7] studied the mechanical properties of woven natural-fiber fabrics in terms of the breaking strengths of warp and weft under 3D loadings. 3. © 2018 Elsevier Ltd. All rights reserved. The integral molding technology can effectively improve the node strength, and the foam core can increase the sectional moment of inertia of bars and avoid local buckling in thin-walled structures [26]. The ramie plant has been cultivated in eastern Asia for fibre since prehistoric times. The comparison between predictions and experimental results is made, and the load-bearing capacity of the proposed structure in unit mass is as high as 24.1 N/g. Sharing links are not available for this article. 2016 [20] developed continuous wound composite truss structures using a simple winding process, conducted experiment against torsion and bending, and optimized the design for the flexural rigidity and the weight. Unlike other bast crops, ramie requires chemical processing to de-gum the fiber. 2014 [11] developed plane truss panels using a pre-tightened tooth connection technology, which connected a glass fiber reinforced polymer (GFRP) tube and a steel joint. 2013 [22] also proposed a design optimization framework for the weight of the same type composite triangular truss utilizing the response surface method to reduce the computational cost. The present invention relates to a process for manufacturing a ramie fabric and the fabric. To read the fulltext, please use one of the options below to sign in or purchase access. This paper provides a novel path to manufacture ramie fibers without alkali. Through the comparison of these. Also, compared to carbon or glass fabric, fiber fabric is more environment-friendly and economical. The fact that the fabric ramie, said and used in its production of fiber - one of the best materials of plant origin. An optical fiber is a single, hair-fine filament drawn from molten silica glass. Unlike steel truss members that can be welded, FRP joining is complicated due to material anisotropy and poor interlaminar strength. Fig. Results showed that the fiber qualities, including residual gum content (4.68%), average fiber fineness (1419.99 Nm) and breaking tenacity (5.98 cN/dtex), were comparable with the traditional alkali process, which all meet the requirement of the relevant Chinese National Standards. Hagenlocher et al. Ramie is one of the oldest fiber crops, having been used for at least 6,000 years, and is principally used for fabric production. Ring spinning is the oldest type of fiber spinning still in use. 831-844, Composite Structures, Volume 243, 2020, Article 112173, Construction and Building Materials, Volume 262, 2020, Article 120535, Composites Part A: Applied Science and Manufacturing, Volume 132, 2020, Article 105809, Reactive and Functional Polymers, Volume 157, 2020, Article 104772, Design, manufacturing and analysis of a ramie fiber triangular structure with the integral molding technology, technology were used to fabricate the structure. The integral molding technology and the prepreg technology were used to fabricate the structure. It was manufactured using the integral molding technology. In this study, ramie bast was pretreated by steam explosion and then treated with deep eutectic solvent. These insights are fundamental to the performance benchmarking including the development of vibration-based condition monitoring and inspection for predictive bridge component maintenance. This paper investigates analytically the non-linear buckling and post-buckling of functionally graded material (FGM) variable thickness toroidal shell segments subjected to axial compression, external pressure, including temperature effects. The production process of ramie is highly labor intensive, especially the process of extracting and cleaning the fibers. They can improve the energy-intensive and unsustainable production processes of synthetic fiber and polymers while increasing the recyclability of polymer matrix composites [1], [2], [3]. Ramie fiber weave fabric is used as the main material in this study to manufacture a triangular structure. Ju et al. https://doi.org/10.1016/j.compstruct.2018.05.017. To enable the manufacture and assembly of composite structures, this study designed a foam joint mold, in which manual winding and mold-pressing technologies were used to fabricate the joints in order to increase the strength of a joint. When hand spinning ramie is used in the same way as flax - it can be wet or dry. 1a. The current paper is the world’s first to present a comprehensive, state-of-the-art overview of the development of meta-functional composites for bridge bearing applications, exposed to both static and dynamic conditions. the site you are agreeing to our use of cookies. Jute is a coarse, brown fiber from the stalk of the bast plant, grown in India. Introduction. Ju et al. The integral molding technology has many advantages, such as the high strength of joints, light-weight of joints, and high production efficiency. The traditional manufacturing process of ramie fibers requires a large amount of alkali, which causes serious environmental issues. Taken together, these data indicate that the novel alkali-free method is green and effective in manufacturing ramie fibers. Jiang, F, Shao, K. Testing method of breaking strength of ramie fiber, GB 5886-86.

To investigate the mechanical properties of ramie fiber-reinforced composites, a significant amount of theoretical and numerical analyses and experiments have been carried out in recent years including the following studies: Chen et al. These works provided efficient methods to develop lightweight truss structures, but they could only be applied to structures subject to a relatively small load because the joints can be easily damaged, and the longitudinal and helical members always suffer from local compressive buckling. Ramie can be blended with cotton, flax, wool, polyester, acrylic and silk of all types. The ANSYS parametric design language (APDL) is used to optimize the topology of the structure by minimizing its weight. The high-temperature oxidation resistance of corundum graphite composite materials could be effectively improved by using phenolic resin with nickel nitrate as the binder, which demonstrates it to be a promising binder for high-temperature application. Manufacturing process 3.1. An analytical method is presented in this paper to solve the energy absorption capacity of composite reinforced metal hemispherical shells undergoing axial compression.
