This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Natural fibers show potential to replace glass fibers in thermoset and thermoplastic composites. Kenaf is a bast-type fiber with high specific strength and great potential to compete with glass fibers. In this research kenaf/epoxy composites were analyzed using Dynamic Mechanical Analysis (DMA). A three-point bend apparatus was used in the DMA testing. The samples were tested at 1 hertz, at a displacement of 10 Îơm, and at room temperature. The fiber volume content of the kenaf was varied from 20%-40% in 5% increments. Ten samples of each fiber volume fraction were manufactured and tested. The flexural storage modulus, the flexural loss modulus, and the loss factor were reported. Generally as the fiber volume fraction of kenaf increased, the flexural storage and flexural loss modulus increased. The loss factor remained relatively constant with increasing fiber volume fraction. Woven and chopped fiberglass/epoxy composites were manufactured and tested to be compared with the kanaf/epoxy composites were manufactured and tested to be compared with the kenaf/epoxy composites. Both of the fiberglass/epoxy composites reported higher flexural storage and flexural loss modulus values. The kenaf/epoxy composites reported higher loss factor values. The specific flexural storage and specific flexural loss modulus were calculated for both the fiberglass and kenaf fiber composites. Even though the kenaf composites reported a lower density, the fiberglass composites reported higher specific mechanical properties.

Download or read book Natural Fiber Based Composites written by Philippe Evon and published by . This book was released on 2021 with total page 350 pages. Available in PDF, EPUB and Kindle. Book excerpt: Entitled “Natural Fiber-Based Composites”, this Special Issue has the objective to give an inventory of the latest research in the area of composites reinforced with natural fibers. Fibers of renewable origin have many advantages. They are abundant and cheap, they have a reduced impact on the environment, and they are also independent from fossil resources. Their ability to mechanically reinforce thermoplastic matrices is well known, as their natural heat insulation ability. In the last twenty years, the use of cellulosic and lignocellulosic agricultural by-products for composite applications has been of great interest, especially for reinforcing matrices. The matrices can themselves be of renewable origin (e.g., proteins, starch, polylactic acid, polyhydroxyalkanoates, polyamides, etc.), thus contributing to the development of 100% bio-based composites with a controlled end of life. This Special Issue's objective is to give an inventory of the latest research in this area of composites reinforced with natural fibers, focusing in particular on the preparation and molding processes of such materials (e.g., extrusion, injection-molding, hot pressing, etc.) and their characterization. It contains one review and nineteen research reports authored by researchers from four continents and sixteen countries, namely, Brazil, China, France, Italy, Japan, Malaysia, Mexico, Pakistan, Poland, Qatar, Serbia, Slovenia, Spain, Sweden, Tunisia, and Vietnam. It provides an update on current research in the field of natural fiber based composite materials. All these contributions will be a source of inspiration for the development of new composites, especially for producers of natural fibers, polymer matrices of renewable origin and composite materials. Generally speaking, these new materials are environmentally friendly and will undoubtedly find numerous applications in the years to come in many sectors. Dr. Philippe Evon Guest Editor.

Download or read book Mechanical Morphological and Thermal Properties of Hybrid Kenaf Fiber nanoclay Reinforced Polylactic Acid PLA Biocomposite written by Mohammad Rejaul Kaiser and published by . This book was released on 2012 with total page 220 pages. Available in PDF, EPUB and Kindle. Book excerpt: The biocomposites based on polylactic acid (PLA), short kenaf fiber and nanoclay hybrid is prepared through different processing method. The processes used are single and double compounding method using twin screw extruder followed by injection moulding. The mechanical properties of blended biocomposites are studied through tensile, flexural and impact tests. The morphology of the composites were characterized by scanning electron microscopy (SEM) and transmission electrom microscopy (TEM). The thermal properties are characterized by using differential scanning calorimetry (DSC), thermogravimetry analysis (TGA) and dynamic mechanical analysis (DMA). Besides these X-ray diffraction (XRD) and fourier transform infra-red (FTIR) analysis was carried out to know the nanoclay dispersion, percentage of crystallinity and possible bond formation. The aim of this work is to hybridize nanoclay and short kenaf fiber in polylactic acid (PLA) by using double extrusion method and followed by mechanical, thermal and morphological characterization. Mechanical properties show improvement with nanoclay, specifically impact strength increases more than 50% than unreinforced PLA. Double extruded hybrid biocomposite shows 3-10% better tensile and flexural properties than the single extruded. Similarly, addition of nanoclay increases decomposition and melting temperature (Tm) from 198 oC to 225 oC and 152 oC to 155 oC respectively. Crystallization temperature (Tc) is however decreases with nanoclay from 116 oC to 106 oC and storage modulus (E") are increased by about 1GPa. These findings were also supported by scanning electron micrograph (SEM) and transmission electron micrograph (TEM) where in double extruded hybrid biocomposite better dispersion of nanoclay were observed. As for X-ray defraction (XRD) and Fourier transform infra-red (FTIR) spectroscopy, higher percentage of crystallinity and formation of new bonds respectively were seen with the addition of nanoclay, which indicates on enhancement in thermal and mechanical properties of PLA-based hybrid biocomposite.

Available in PDF, EPUB and Kindle. Book excerpt: Dynamic Mechanical Analysis (DMA) is a powerful technique for understanding the viscoelastic properties of materials. It has become a powerful tool for chemists, polymer and material scientists, and engineers. Despite this, it often remains underutilized in the modern laboratory. Because of its high sensitivity to the presence of the glass transition, many users limit it to detecting glass transitions that can’t be seen by differential scanning calorimetry (DSC). This book presents a practical and straightforward approach to understanding how DMA works and what it measures. Starting with the concepts of stress and strain, the text takes the reader through stress–strain, creep, and thermomechanical analysis. DMA is discussed as both the instrument and fixtures as well as the techniques for measuring both thermoplastic and thermosetting behavior. This edition offers expanded chapters on these areas as well as frequency scanning and other application areas. To help the reader grasp the material, study questions have also been added. Endnotes have been expanded and updated. Features Reflects the latest DMA research and technical advances Includes case studies to demonstrate the use of DMA over a range of industrial problems Includes numerous references to help those with limited materials engineering background Demonstrates the power of DMA as a laboratory tool for analysis and testing
