摘要：
Furan resin and fir powder pretreated by FeCl<inf>3</inf>and aqueous ammonia solution were used to fabricate α-Fe/Fe<inf>3</inf>C/woodceramic nanocomposite. The bands of the pretreated wood powder were characterized by Fourier transform infrared spectroscopy (FTIR). The structural characterization of the nanocomposites was performed by scanning electron microscopy (SEM) and X-ray diffraction (XRD). The microwave absorption of the nanocomposites was measured by a vector network analyzer in the range of 2-18 GHz. The mechanical properties of the composites were also investigated. XRD and SEM results show that the α-Fe and Fe<inf>3</inf>C nanoparticles are in-situ generated and disperse in the matrix of the woodceramic. The diameters of these nanoparticles increase with the increasing of concentration of FeCl<inf>3</inf>solution. The experimental results show that both the complex permittivity and the complex permeability of α-Fe/Fe<inf>3</inf>C/woodceramic nanocomposites increase as the concentration of FeCl<inf>3</inf>solution increases. The composites pretreated with 0.60 mol·L<sup>-1</sup>FeCl<inf>3</inf>have the best absorption properties. The maximum value of reflection loss (RL) at 3 mm thickness reaches -25.60 dB at 10.16 GHz and the bandwidth below -10 dB is about 2.5 GHz. Compared to woodceramic, the bending strength and compressive strength of α-Fe/Fe<inf>3</inf>C/woodceramic nanocomposites increase by 22.5% and 18.7% at most, respectively.<br/> ©2018 by the authors.

摘要：
Wood furfurylation is a very promising modification process, which can greatly improve several important properties of wood simultaneously. The polymerization degree of furfuryl alcohol (FA) in wood significantly influences the performances of modified wood. However, it is normally time-consuming and expensive to determine the curing parameters of a new FA solution formula for a target wood species, as the process requires lots of lab-scale experiments. To address this challenge, nanoindentation was used to determine the hardness and elastic modulus of FA resin which are cured with different catalyst content, curing time and curing temperature, assuming that these mechanical properties should closely relate to the polymerization degree of cured FA (resin). Single-factor experiments were designed to obtain preliminary curing parameters. Three key curing parameters were selected, namely the catalyst content of maleic anhydride (1.5, 3, 5%), curing time (2, 3, 4, 5, 6h) and curing temperature (95, 105, 115, 125°C). The proposed set of curing parameters based on the nanoindentation results are 3% maleic anhydride, 3h curing time and 105°C curing temperature. This set of parameters was slightly modified and then used as the starting process parameters for Masson pine modification, which resulted in greatly improved wood properties. Therefore, the method proposed in this study offers an effective and time-saving means of developing new processes of wood furfurylation. © 2016, Springer-Verlag Berlin Heidelberg.

摘要：
This study describes a process to apply response surface methodology (RSM) together with a niched Pareto genetic algorithm for optimization of the mechanical properties of bamboo plywood. Experiments were carried out to investigate the dependences of parallel and perpendicular modulus of rupture (MOR) and modulus of elasticity (MOE) of bamboo plywood on hot-pressing temperature, hot-pressing time, pressure, amount of adhesive, and moisture content. Empirical equations were presented to describe the dependences. Orthogonal tests and RSM were used to establish models for MOE and MOR of bamboo plywood in the parallel and perpendicular directions. Solutions of the models were obtained by means of a Pareto genetic algorithm. By comparing the solutions with given initial values, the optimized parallel and perpendicular MOR were increased by 19.52 and 23.35%, respectively, and the optimized parallel and perpendicular MOE by 21.50 and 12.57%, respectively. Based on the optimization, typical panel operational parameters were hot-pressing temperature 163.3 degrees C, hot-pressing time 17.6 min, hot-pressing pressure 4.0 MPa, amount of adhesive 8.9%, and MC 15.7%. Results from this study are useful to bamboo plywood mills for selecting operational parameters to determine mechanical properties of bamboo plywood, which will decrease workload and time in determining technical parameters to manufacture bamboo plywood with expected MOE and MOR.

摘要：
Due to its potential for commercial applications, wood modification with furfuryl alcohol (FA) is now attracting enhanced attentions from researchers and industry. Selection of suitable catalysts to control the polymerization of FA during storage and curing is the most crucial component of this technology. In this paper, a new composite acidic catalyst composed of oxalic acid and citric acid was proposed and compared with the widely adopted maleic anhydride catalyst, with Masson pine (Pinus massoniana Lamb) as the objective of modification. Weight percent gain, equilibrium moisture content, anti-swelling efficiency, modulus of rupture, modulus of elasticity and parallel-to-grain compressive strength (CS), as well as resistance to mould and decay fungi were all evaluated. The results show that furfurylation significantly improves the dimensional stability and durability of pine wood. Furthermore, most of the mechanical properties were also enhanced, especially CS, which increased by approximately 79 and 95 % under the two respective catalysts. Overall, the newly proposed composite acidic catalyst produced comparable results to maleic anhydride with much less FA required.

摘要：
A simple, practical, and low-technology approach was developed to fabricate corrugated bamboo particleboards (CBP), a novel bamboo product with a corrugated structure, from bamboo waste (planer waste). This product could be manufactured anywhere in the world where the bamboo industry develops. The selected mechanical and physical properties of CBP were prepared with urea formaldehyde resin at three press temperatures and two density levels and were evaluated. The results showed that the performance of CBPs is highly dependent upon the board density. The static bending strength of CBP laminated with MDF initially increases, and then decreases with increasing press temperature. Increasing the magnitude of the press temperature has a slightly positive effect on the thickness swelling and water absorption. Compared with the excellent mechanical strength of CBP (laminated with MDF), the thickness swelling value of this bamboo-based particleboard without any waterproofing treatment was lower than the minimal requirement of the EN standard.

摘要：
Fe/Woodceramics(Fe/WCMs) composites are prepared by dipping bamboo powder into ferric salt solution, dropping alkali, mixing with furane resin, and then having the mixture molded and finally sintered in high temperature. Microstructures of Fe/WCMs are measured by using X-ray diffraction(XRD) and scanning electron microscopy (SEM). XRD results indicate that the characteristic peaks of Fe are found. SEM photographs show that Fe crystals are distributed in the glassy carbon. The effects of concentration of ferric salt on volume shrinkage ratio and volume electrical resistivity of the composites are investigated. The results show that the volume shrinkage ratio and the volume electrical resistivity decrease with an increase in concentration of ferric salt. ©2012 IEEE.

The effect of carbonization temperature on carbon yield ratio,volume shrinkage ratio and volume electrical resistivity of woodceramics were investigated. The results show that carbonization temperature has a significant effect on the microstructure of woodceramics. When the carbonization temperature increases, the volume shrinkage ratio increases, and the carbon yield ratio and the volume electrical resistivity decrease. ©(2012) Trans Tech Publications, Switzerland.

摘要：
研究了竹粉/高密度聚乙烯(HDPE)复合材料的生产工艺,对其多项性能进行测试。采用双辊开炼机进行复合材料的共混制备;熔融指数仪测定不同配比复合材料的流动性;注塑成型机制备各种标准力学性能试样;拉力试验机和冲击试验机测试力学性能。结果表明随着竹粉含量的增加,材料熔融流动性大大降低;冲击强度下降明显;拉伸强度首先上升,在竹粉含量超过30%后又下降;注塑成型制品收缩率下降。
