Review Reports

Natural fibers are extracted from natural resources such as stems of plants. In contrast to synthetic fibers (e.g., carbon fibers), natural fibers are from renewable resources and are eco-friendlier. Plant fibers are important members of natural fibers. Review papers discussing the microstructures, performances and applications of natural plant fiber composites are available in the literature. However, there are relatively fewer review reports focusing on the modeling of the mechanical properties of plant fiber composites. The microstructures and mechanical behavior of plant fiber composites are briefly introduced by highlighting their characteristics that need to be considered prior to modeling. Numerical works that have already been carried out are discussed and summarized. Unlike synthetic fibers, natural plant fiber composites have not received sufficient attention in terms of numerical simulations. Existing technical challenges in this subject are summarized to provide potential opportunities for future research.

Influence Of Water

Geopolymer-based plant fiber composites were fabricated with metakaolin, alkaline sodium silicate and plant fibers. In this paper, orthogonal test and single factor analysis were used to study the influence of water glass modulus, solid liquid ratio and fiber content on bending strength. The results show that sequence of influence factors for bending strength was: solid to liquid ratio > fiber content > water glass modulus. When the water glass modulus is 1.7, the fiber content is 8% and the solid to liquid ratio is 1:1.4, the bending strength is up to 10.44MPa, which exceeds the Standard requirements (9MPa) specified by the China National Standard (GB/T 24312-2009). The micro-morphology of SEM indicates that the mix of plant fiber can enhance the toughness of geopolymer.

Researches in plant fiber composites have been developed with greater frequency during the last years, especially on environmental issues. The opening of the market, especially in the automotive sector, points to the replacement of synthetic additives by natural reinforcements. Characteristics such as low density and abrasiveness, superior mechanical properties and low cost are the most sought in these composites. The aim of this study was to evaluate the behavior of composites based polyester matrix and fiber of the babassu coconut epicarp, at levels of 5, 7.5 and 10% under testing of tensile strength and impact, as well as the morphology by microscopy scanning electron and water absorption. All composites were prepared raw fibers and fiber with treated with alkaline solution of 5% NaOH. As regards the mechanical properties, an increasing of the rigidity of the system was observed, and the kinetics of water absorption increased levels indicated for compounds with high content of fibrous reinforcement. By SEM there was greater interaction between fiber and matrix.

The foaming effect of the biodegradable buffer material was investigated in this paper. Starch, plant fiber, plasticizer and nucleating agent were mixed, and the mixture was molded. After completion of preparation of materials, the porosity of material was calculated. Porosity reflects the foaming effect of the buffer material. Many factors determine the foaming effect of biodegradable buffer material. The primary and secondary factors were shown: foaming temperature>particle size>foaming time>the ratio of starch and fiber. The porosity of biodegradable buffer material can reach as much as 72.02 percent.

Background: With the improvement of environment protection awareness, human beings have gradually become aware of that the plastic products, waste are harmful to the human living environment. Therefore, research and application of biodegradable materials that do not rely on petroleum resources have become hot topics. Researchers have accelerated the development and promotion of plant fiber because they are good flexibility, relatively rough surface and biodegradable. Objective: The development of plant fiber composites is reviewed, including composition ratio, interfacial modification, processing technology, and the effects of these technologies on the properties of plant fiber composites. Methods: The paper reviews various patents and research developments about plant fiber composite materials. It also analyzes the advantages and disadvantages of various patents and technologies from the aspects of biodegradable ability, mechanical properties, dispersing performance, processing properties, cost, and so on. Results: The component proportion, interface modification, and processing technology of plant fiber composite materials are prospected to improve the quality and application of the plant fiber composite materials in the future development. Conclusion: The considerable attention has been paid on the technology of biodegradable plant fiber composite. The recent patents and technologies have shown us a wider application in biodegradable plant fiber composite. The problems how to improve the mechanical properties of plant fibers, the dispersion properties of plant fibers and resins, and the processing properties of composite materials, will need more and more methods and equipment to solve or simplify.
