Abstract

Japanese larch (Larix kaempferi) boxed-heart timbers with the dimension of 100 × 100 × 1,000 mm were dried after being steamed at 100°C and 0°C wet-bulb depression for 5 hours, and then dried at 120°C and 30°C wet-bulb depression for 8, 12, and 16 hours, respectively. The radial permeability of the ...

Abstract

To improve fire-retardant performance of Japanese larch (Larix kaempferi) wood, this study analyzed the effect of pinholes made by laser incising and fire retardant (FR) coating on the surface of Japanese larch wood. Combustion properties such as peak heat release rate (PHRR) and total heat release ...

Abstract

Log characteristics and basic density were evaluated in four common Mongolian softwoods, Pinus sylvestris L., Pinus sibirica Du Tour, Picea obovata Ledeb., and Larix sibirica Ledeb. by developing the linear or nonlinear mixed-effects models for longitudinal and radial variations of measured...

Abstract

This study was conducted to confirm the effects of combined radio-frequency/vacuum-press (RF/VP) drying on the strength properties of Japanese larch board. The strength properties of board dried at RF/VP was evaluated in comparison with conventional kiln, high-temperature, hot-air/vacuum dried, and ...

Abstract

The objective of this study was to evaluate the moisture profile and drying period of air drying the red pine and Japanese larch timbers with the cross section of 14.0 cm × 14.0 cm and 16.5 cm × 16.5 cm by measuring the electric resistance of the wood. The drying curves determined by measuring...

Abstract

Wood properties, including Young's modulus, differ among clones in Larix kaempferi; however, available information is still limited on among-clonal variations of lumber qualities in L. kaempferi. The objectives of this study were to clarify the clonal variations in lumber quality and to identify...
