The RT-CaCCO process for enzymatic saccharification was applied to readily-milled fractions of wet sugarcane bagasse. Wet bagasse immediately after juice extraction was crushed with shark-mill blades to prepare two fractions referred to as readily-milled (RF) and hardly-milled fraction (HF). Monosaccharide recoveries from RFs via the RT-CaCCO process were 1.03-1.21 times higher than those from ...

Here we propose a macroscopic model for elasto-plastic composite, characterized by an initial anisotropy, that can evolve during the large plastic deformation. Application to transversely isotropic and orthotropic composites will be also developed. The paper deals with anisotropic finite elasto-plastic 6-models, which accounts for the dissipative nature of the plastic flow, within the construct...

Non-isothermal crystallization of neat high density polyethylene (HDPE), wood flour (WF)/HDPE composite (WPC), virgin Kevlar fiber (KF) reinforced WPC (KFWPC), and grafted Kevlar fiber (GKF) reinforced WPC (GKFWPC) was investigated by means of differential scanning calorimetry (DSC) and wide angle X-ray diffraction (WAXD). Several theoretical models were applied to describe the process of nonis...

Composites were manufactured from glass fiber, bagasse fly ash, and epoxy matrix examined their mechanical physical properties. The percentages of fine designed at 10%, 15%, 20%, 25%, 30% with fiber conducted density, flexural strength, hardness, absorption water, swelling properties thickness. prepared by manual layering. ASTM standards followed in preparing the samples. According to results, ...

The objective of this study is to investigate an appropriate process to fabricate the wood-polyurethane hybrid composites [wood-polyurethane foam (PUF)]. Rigid PUFs that contain up to 20% wood flours were successfully fabricated from polymeric 4,4-diphenylmethane diisocyanate, polyols, silicone surfactant, dibutin dilaurate/ dimethylethanolamine catalysts, and distilled water (chemical blowing ...

Graphene nanoplatelets (GNP) are used to produce wood plastic composites (WPC) with improved electrical and thermal conductivity. The polypropylene/wood/GNP hybrid produced by melt compounding followed hot pressing. effect of GNP loadings (5, 10 15 wt%) on conductivity, tensile properties, degradation WPC containing 20 wt% flour is studied. fast slow cooling rates during pressing the surface re...

Agricultural waste such as sugarcane and paddy are common during harvesting to production process. Sometimes they burned after the harvest process, consequently environmental problem got multiply. Demand for Composite Material inflate recently, because lighter stronger than Polyethylene Plastic. Filler in composite materials is expensive requires precise design. The aim of this research create ...

Studies were conducted to evaluate Bacillus atrophaeus spores’ production by solid-state fermentation (SSF) using sugarcane bagasse as support and soybean molasses as substrate at lab-scale in column bioreactors (forced aeration), plastic bags and Erlenmeyer flasks (aeration by diffusion). Different moisture contents (84%, 86% and 88%; 89%, 91% and 93%) and aeration rates (30mL/min, 45mL/min, 6...

We consider fiber reinforced composites where both the matrix and the fibers are ideally plastic materials. We restrict our attention to microstructures and applied stresses that lead to both microscopic and macroscopic antiplane shear deformations. We describe a bound we have recently obtained on the yield set of the composite in terms of the shape of the fibers, their volume fraction, and the...

in this study, the disadvantages of wood, which is widely employed in producing music instruments, are discussed. for example, high moisture sensitivity, low impact resistance, and time-consuming procedure as well as various properties of different species or in several parts of one specimen which are the main problems of wooden music instruments are extensively discussed in this paper. many ma...
