High optical transmittance can be obtained if the refractive index of the two different phases are similar. Glass fiber reinforced polymers [3] is another example of potentially transparent composites, but transparent wood has particular potential as a more eco-friendly composite, in combination with ...
The values of Chinese fir’s wood physical properties varied considerably among different geographic sources and Tukey-HSD testing showed that some of these differences were statistically significant (Fig.1). The maximum value (HNYX-T) of wood all-dry density (WDD) was 62.70% higher than the m...
Secondly, we address the question regarding the influence of the polypeptide primary structure on silk material properties by analysing the experimental results in terms of the underlying fibroin amino acid sequences from the different species. Fourteen types of cocoon silks were investigated, ...
Rapid identification and quantification three chicken-wing woods of Millettia leucantha, Millettia laurentii and Cassia siamea by FT-IR and 2DCOS-IR The chicken-wing wood belongs to "hongmu", which comes from the heartwood of three kinds of trees, M. leucantha , M. laurentii and C. siamea...
摘要: Results are presented on the temperature dependence of the dielectric loss factor for beech veneers containing methanol, acetone, pyridine or diethylamine.关键词: electrical properties improved wood mechanical properties physical properties wood properties ...
Under long-term loading, the mechanical properties of geogrids in eco-bag reinforced soil retaining walls (ERSW) gradually weaken due to creep and photo-oxidative aging. In contrast, the continuously growing roots transfer their tensile strength to soil shear strength. However, the reinforcing effec...
Silk has attracted widespread attention due to its superlative material properties and promising applications. However, the determinants behind the variations in material properties among different types of silk are not well understood. We analysed the p
