Preparation and characteristics of moulded biodegradable cellulose fibers/MPU-20 composites (CFMCs) by steam injection technology

Optimizing Refining Conditions of Pinus massoniana Cellulose Fibers for Improving the Mechanical Properties of Ultra-Low Density Plant Fiber Composite (ULD_PFC)

“…This is because the combination among fibers and their intrinsic properties are crucial for the mechanical properties of ULD_PFCs. As an increase in the pulp consistency, the fibers are remarkably broken and fibrillated because of the function of the friction among fibers (Clark 1985;Chu and Ou 2001;Liu et al 2008;Gao et al 2012). As shown in Fig.…”

“…Also, the tear index of the optimal specimen was 13.9% and 24.5% higher than specimen-1 with a lowest beating degree of 24 o SR and specimen-6 with a highest beating degree of 73 o INTRODUCTION Ultra-low density plant fiber composite (ULD_PFC) is a foaming material with many advantages, such as low thermal conductivity and a high coefficient of sound absorption (Xie et al 2004(Xie et al , 2008a(Xie et al , 2008b(Xie et al , 2011. It is derived from plant fibers that are renewable and biodegradable polymers, mainly consisting of cellulose, lignin, and hemicelluloses (Liu et al 2008). The plant fiber composite is produced using a liquid frothing process without heating, pressing, or common adhesives.…”

A Review on Biodegradable Polymeric Materials Striving Towards the Attainment of Green Environment

“…Twin screw extruder process was adopted to prepare thermoplastic biodegradable composites using polyesters and polysaccharides as matrix. The composites prepared from polysaccharides showed enhanced mechanical properties compared to [99] adopted steam injection technology to prepare cellulose fiber reinforced polyurethane (MPU-20) composites. Compressive stress-strain and cushion factor-stain values were measured based on the injection pressure, transmission time, holding time, resin content, specific gravity.…”

“…Flour surface treatment i.e., acetylation, propionylation, addition of maleic anhydride-grafted-polyester and dicumyl peroxide as initiator showed better flourmatrix interfacial bonding. The addition of compatibilizer and surface treatment of flour depicts improved mechanical behavior, biodegradation rate and reduction in water uptake properties.DetaoLiu et al (2008) …”

Preparation and Properties of Foamed Cellulose-Polymer Microsphere Hybrid Materials for Sound Absorption

“…In 2008, our research group reported the preparation of biocomposites composed of biodegradable cellulose fibers and polyurethane adhesive . These composites exhibit promising sound-absorption properties and have higher absorption coefficients over a wide frequency range (250 to 7000 Hz) (Liu et al 2008). In 2011, our group also fabricated a new green sound-absorbing hybrid material via pulp fibrous models, in which the natural pulp fibers have appreciable sound-absorbing properties because of their technical advantages, including being porous, flexible, and easy fibrillated, compared with inorganic glass-and aluminum-silicate fibers (Liu et al 2012).…”
