Available in PDF, EPUB and Kindle. Book excerpt: To restore and maintain forest ecosystem health and function in the western interior of the United States, many small-diameter stems need to be removed from densely stocked stands. In general, these materials are underutilized. Information on the properties of these resources is needed to help forest managers understand when timber sales are a viable option to accomplish ecosystem management objectives. Providing proof that this small-diameter material yields quality pulp would help increase its value and therefore help remove it from the forest. This study examines the acceptability of the small-diameter resource as a raw material for high-yield chemithermomechanical pulping (CTMP), which has the potential for improved fiber characteristics and paper strength compared with those of thermomechanical pulping (TMP). Pulps using CTMP were prepared from lodgepole pine and mixed Douglas-fir/western larch sawmill residue chips; lodgepole pine, Douglas-fir, and western larch submerchantable logs; and lodgepole pine, Douglas-fir, and western larch small trees. These small-diameter pulps were compared with commercially obtained sawmill residue chips of a Douglas-fir/western larch mixture and lodgepole pine. These pulps were also evaluated to see if CTMP improved the properties of the final product compared with products made using TMP. Compared with the controls, the CTMP prepared from Douglas-fir and lodgepole pine small trees and Douglas-fir submerchantable logs consumed more electrical energy during pulp preparation and had higher paper strength properties and lower optical properties. Also compared with the controls, lodgepole pine submerchantable logs consumed about the same electrical energy and had marginal strength properties and higher optical properties. Western larch submerchantable logs and small trees had the lowest electrical energy consumption of all pulps tested, low strength properties, but some of the higher optical properties. Western larch submerchantable logs and small trees appear to be unsuitable for CTMP. For the majority of the materials, CTMP improved the properties of the final product compared with corresponding TMP.

Book Synopsis Natural Fibre Composites by : Alma THULE
Download or read book Natural Fibre Composites written by Alma THULE and published by Woodhead Publishing. This book was released on 2014-02-13 with total page 409 pages. Available in PDF, EPUB and Kindle. Book excerpt: The use of natural fibres as reinforcements in composites has grown in importance in recent years. Natural Fibre Composites summarises the wealth of significant recent research in this area. Chapters in part one introduce and explore the structure, properties, processing, and applications of natural fibre reinforcements, including those made from wood and cellulosic fibres. Part two describes and illustrates the processing of natural fibre composites. Chapters discuss ethical practices in the processing of green composites, manufacturing methods and compression and injection molding techniques for natural fibre composites, and thermoset matrix natural fibre-reinforced composites. Part three highlights and interprets the testing and properties of natural fibre composites including, non-destructive and high strain rate testing. The performance of natural fibre composites is examined under dynamic loading, the response of natural fibre composites to impact damage is appraised, and the response of natural fibre composites in a marine environment is assessed. Natural Fibre Composites is a technical guide for professionals requiring an understanding of natural fibre composite materials. It offers reviews, applications and evaluations of the subject for researchers and engineers. Introduces and explores the structure, properties, processing, and applications of natural fibre reinforcements, including those made from wood and cellulosic fibres Highlights and interprets the testing and properties of natural fibre composites, including non-destructive and high strain rate testing Examines performance of natural fibre composites under dynamic loading, the response of natural fibre composites to impact damage, and the response of natural fibre composites in a marine environment

Download or read book Green Biorenewable Biocomposites written by Vijay Kumar Thakur and published by CRC Press. This book was released on 2016-01-05 with total page 568 pages. Available in PDF, EPUB and Kindle. Book excerpt: Keeping in mind the advantages of bio-based materials, this book focuses on the potential efficacy of different biocomposites procured from diverse natural resources and the preparation and processing of the biocomposites to be used for a variety of applications. Each chapter gives an overview on a particular biocomposite material and its processing and successful utilization for selected applications. The chapters summarize recently developed research on such topics as: • Spider silk biocomposites • Biogenic hydroxyapatite-based implant biocomposites • Liquid crystals and cellulose derivatives biocomposites • Bio-based epoxy resins • Bio-based polyphenols and lignocellulosic fibers • Wood-based biocomposites • Flame retardant biocomposites • Biocomposites for industrial noise control • Cellulose-based bionanocomposites Each individual chapter also focuses on the knowledge and understanding of the interfaces manifested in these biocomposites systems and the optimization of different parameters for novel properties. In addition to this, the book also summarizes the recent developments made in the area of injection molding of biocomposites, chemical functionalization of natural fibers, processing of biocomposites, and their applications in the automotive and biomedical industries. A number of critical issues and suggestions for future work are discussed, underscoring the roles of researchers for the efficient development of biocomposite materials through value addition to enhance their use.
