“…Previously studied water absorption results were also found to be similar to our findings , Ayrilmis et al 2011. It is reported in the literature that mechanical properties of some composite materials are adversely affected from increasing heat treatment temperature (Bekhta et al 2003, Okino et al 2007, Pan et al 2010, Ayrilmis et al 2011. Tensile strength is one of the most important indicating factors for mechanical properties of MDF.…”

This work investigated some mechanical, physical and free formaldehyde emission properties of heat-treated MDF. For this purpose, MDF panels were subjected to varying heat treatment temperatures (155°C, 165°C and 175°C), durations (2.5 h., 3.5 h. and 4.5 h.) and waiting times after hot pressing (30 min., 120 min. and 600 min). Thickness swelling (TS), water absorption (WA), free formaldehyde emission (FFE), bending strength (BS), modulus of elasticity (MOE), tensile strength perpendicular to fibers (TSPF) for treated and untreated samples were tested and evaluated statistically. Consequently, after the heat treatment values of tensile strength, bending strength and modulus of elasticity were almost negatively affected relatively, but the thickness swelling and water absorption and quantities of free formaldehyde were improved positively of MDF samples.

Abstrak Papan zephyr dapat dibuat dari pelepah sawit dari limbah perkebunan kelapa sawit. Penelitian ini bertujuan membandingkan kualitas Papan Zephyr Pelepah Sawit (PZP) dengan beberapa jenis papan bio-komposit komersial 617.6(x10² kg.cm⁻²), 728.47(x10² kg.cm⁻²), 398.74 (x10² kg.cm⁻²) and 199.22(x10² kg.cm⁻²), and that of MOR of each board was 405 kg cm⁻², 541 kg cm⁻², 207 kg cm⁻², and 119 kg cm⁻², while the screw holding strength of each was 88.49 kg, 92 kg, 53.6 kg and 61.4 kg, respectively.

Purpose The paper aims to present an investigation of wood bonding strength as a very important indicator for effective using in further manufacturing processes. Design/methodology/approach In this study, the wood bonding strength sensitivity was estimated based on grain orientation, feed speed, heating time and temperature, temperature and type of adhesive. Artificial intelligence methods were applied for this analysis because it is strongly a nonlinear process. Findings It was shown that the artificial intelligence tools could be useful, reliable and effective for the wood bonding strength sensitivity estimation. Afterwards the power consumption in in solid wood machining process is analyzed and estimated by the artificial intelligence tools. Originality/value Results shown that the wood bonding strength is the most sensitive for type of adhesive. Thus, the results of the present research can be successfully applied in the wood industry to reduce the time, energy and high experimental costs.
