Understanding wetting behavior and surface coverage of resins on a wood surface is important to obtain satisfactory adhesion and optimize adhesive application for wood composite manufacturing. Sessile and micro-droplets of ureaand phenol-formaldehyde (UF and PF) resins were generated on wood surfaces to observe wetting behaviors using three directional image generation system and atomic force m...

Chemical coupling on the thennomechanical pulp (TMF') fiber improved tensile shrength of the TMP fiber handsheet and isotactic polypropylene film laminates (TPL). For the maleic anhydride W) with benzoyl peroxide (%PO) as an initiator, tensile strength i n d 52% with the TMP fiber treatment over untreated laminates. The optimum strength jmperties were obtaiaed with an MA and BPO ratio of 21. Sc...

Differing from the hot-pressing method in the manufacturing of traditional wood-rubber composites (WRCs), this study was aimed at fabricating WRCs using rubber processing to improve water resistance and mechanical properties. Three steps were used to make WRCs, namely, fiber-rubber mixing, tabletting, and the vulcanization molding process. Ninety-six WRC panels were made with wood fiber content...

Conocarpus erectus L. is a fast growing tree, drought resistant and it is widely planted throughout Saudi Arabia around parking lots and along the streets. It constitutes a renewable resource that could be used as a source of raw materials required for several uses. However, no data were available about its wood quality. This study was established to investigate the effect of plant spacing on s...

A lignin-epoxy resin composite was prepared by blending lignin/wood flour with an epoxy resin and polyamine. The effects of the wood flour on the mechanical, thermal creep, and creep recovery properties, as well as the microstructure of the composite, were studied. Among the mechanical properties, the initial modulus increased with increasing content of wood flour. The glass transition temperat...

The objective of the article is to investigate the variability in growth and wood properties of the willow clones. The growth and wood traits of four year old 21 clones willow clones were investigated. Analysis of variance showed that willow clones differed significantly for all the studied growth and wood traits. Among the growth parameters the maximum heritability value was shown by height wh...

In present study 7 carriers such as agar –agarose, wood fiber, wood chips, gelatin, wood powder, calcium alginate and butanol sodium alginate were used for immobilization of fungal amylase. Amylase immobilization was carried out by simple adsorption, adsorption followed by cross-linking, combined adsorption and gel entrapment methods. The suitability of the supports and techniques for the immob...

The far-infrared properties of spruce wood are examined with a terahertz time-domain spectrometer. The solid wood is shown to exhibit both birefringence and diattenuation. The birefringence properties are sufficient for construction of a quarter-wave plate operating at 0.36 THz, and a half-wave plate operating at 0.71 THz. The origin of the birefringence is attributed to preferential fiber orie...
