This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Kenaf fibers have mechanical properties making them a good candidate to replace glass fibers in composites. This research investigates kenaf fiber-reinforced composites, examining the effect of cure time, density, matrix hardener ratio, surface treatment, and fiber length on the mechanical properties of the composite material such as natural frequency, damping loss factor, and tensile modulus. These are essential characteristics for many manufacturing parts and products, but are not well known for natural fiber-reinforced composite materials since interest in utilizing natural fibers for composites is in the infancy phase and determining properties is difficult. Natural fibers display properties similar to glass fibers, and present a more environmentally friendly option for manufacturing composite materials. By studying published research on the topic and experimenting with different methods, a consistent procedure for manufacturing composites was developed and several samples were created for testing these parameters. These samples were subjected to a vibrational test using an impact hammer and accelerometer. Through the half-power bandwidth method and other relationships, mechanical properties were extracted from the test to study the effect of each manufacturing process. Samples were found to exhibit repeatable mechanical properties after approximately 150 hours following removal from the oven. Increasing the pressure applied during the cure cycle results in higher densities, which increases loss factors and tensile moduli, and lowers natural frequencies. The matrix hardener ratio also affects these properties in a similar way. High hardener ratios result in a more brittle material that dampens less but generally has a higher stiffness. Models predict that a chemical surface treatment should decrease the loss factor due to a better fiber-matrix bond, resulting in less sliding and friction. However, testing showed the opposite result with treated fibers exhibiting higher amounts of damping. Fiber length was also tested, though the results showed a less prominent effect.

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 Manufacturing of Natural Fibre Reinforced Polymer Composites written by Mohd Sapuan Salit and published by Springer. This book was released on 2015-09-10 with total page 393 pages. Available in PDF, EPUB and Kindle. Book excerpt: Natural fibre composite is an emerging material that has great potential to be used in engineering application. Oil palm, sugar palm, bagasse, coir, banana stem, hemp, jute, sisal, kenaf, roselle, rice husk, betul nut husk and cocoa pod are among the natural fibres reported to be used as reinforcing materials in polymer composites. Natural fibre composites were used in many industries such as automotive, building, furniture, marine and aerospace industries. The advantages of natural fibre composites include low cost, renewable, abundance, light weight, less abrasive and they are suitable to be used in semi or non-structural engineering components. Research on various aspects of natural fibre composites such as characterization, determination of properties and design have been extensively carried out. However, publications that reported on research of manufacture of natural fibre composites are very limited. Specifically, although manufacturing methods of components from natural fibre composites are similar to those of components from conventional fibre composites such as glass, carbon and Kevlar fibres, modification of equipment used for conventional fibre composites may be required. This book fills the gap of knowledge in the field of natural fibre composites for the research community. Among the methods reported that are being used to produce components from natural fibre composites include hand lay-up, compression moulding, filament winding, injection moulding, resin transfer moulding, pultrusion and vacuum bag moulding. This book is also intended to address some research on secondary processing such as machining and laser welding of natural fibre composites. It is hoped that publication of this book will provide the readers new knowledge and understanding on the manufacture of natural fibre composites.
