“…Composite manufacturing factories have always been confronted with some ongoing issues, such as the emission of formaldehyde, heat transfer to the core of the mat, vulnerability to vapor, and biological susceptibility to fungi and insects [6][7][8][9][10]. Moreover, numerous studies have been focused on the limitation of formaldehyde emission and on the improvement of the resin bond [11]. The heat-transferring properties of metals and improving effects of different materials at micro-and nano-scales [12][13][14][15][16][17] were also found to decrease hot press time and to improve the physicomechanical properties in wood composites [6,18].…”

Wood-composite panel factories are in shortage of raw materials; therefore, finding new sources of fibers is vital for sustainable production. The effects of chicken feathers, as a renewable source of natural fibers, on the physicomechanical properties of medium-density fiberboard (MDF) and particleboard panels were investigated here. Wollastonite was added to resin to compensate possible negative effects of chicken feathers. Only feathers of the bodies of chickens were added to composite matrix at 5% and 10% content, based on the dry weight of the raw material, particles or fibers. Results showed significant negative effects of 10%-feather content on physical and mechanical properties. However, feather content of 5% showed some promising results. Addition of wollastonite to resin resulted in the improvement of some physical and mechanical properties. Wollastonite acted as reinforcing filler in resin and improved some of the properties; therefore, future studies should be carried out on the reduction of resin content. Moreover, density functional theory (DFT) demonstrated the formation of new bonds between wollastonite and carbohydrate polymers in the wood cell wall. It was concluded that chicken feathers have potential in wood-composite panel production.

“…6,[18][19][20][21][22] Wood-based materials and composites are no exception. 23,24 Different nano-metals and nanominerals were utilized to improve the heat-transfer property in solid wood species and wood composite mats; they were also used to improve biological resistance against different deteriorating fungi, 7,9,[25][26][27][28] to decrease hot-press time as a costly bottle-neck in nearly all wood-composite manufacturing factories, and to increase thermal conductivity in solid wood and composite mats. 29 In this connection, wollastonite is a calcium inosilicate mineral (CaSiO 3 ), which contains small amounts of iron, magnesium, and manganese substituting for calcium, that has been proved as nontoxic and harmless for both human health and wildlife.…”

Summary The improving effects of addition of nano‐wollastonite on some fire properties of medium‐density fiberboard (MDF) were studied in this work. Nano‐wollastonite was added at four levels (2%, 4%, 6%, and 8%). The size range of at least 70% of nano‐wollastonite particles were 30 to 110 nm. The results showed statistically significant improving effect of nano‐wollastonite on time to onset of ignition. The improving effect was primarily attributed to an increase in thermal conductivity of board containing nano‐wollastonite. This increase in turn resulted in better curing of resin, and a higher integrity of fibers thereof. Moreover, nano‐particles provided a surface with reduced combustibility and therefore, penetration of fire to the inner layers of boards was delayed, thus improving fire properties. High and significant correlations were found between thermal conductivity coefficients of boards with different fire properties. It was concluded that for applications where fire properties are of prime importance, nano‐wollastonite content of 8% can be recommended. Moreover, further studies are needed to compare and standardize the results obtained from the apparatus used here with those obtained from internationally recognized apparatuses like cone calorimeter.

RESUMO A presente pesquisa tem por objetivo avaliar a influência de três fatores de produção (densidade nominal, temperatura e pressão) na produção de paineis de partículas de média densidade da madeira de Eucalyptus saligna com resina ureia-formaldeído e catalisadores e verificar se os paineis atendem ao requisito normativo da ABNT NBR 14810. A influência dos fatores nos paineis MDP foram analisados por intermédio de 12 tratamentos experimentais. Foram fabricadas 48 chapas ao total, com 4 chapas com dimensões 300 mm x 300 mm x 15 mm, determinando 7 propriedades físicas e mecânicas, totalizando 336 determinações experimentais. Foram avaliadas as seguintes propriedades: teor de umidade, densidade aparente, inchamento em espessura após 2h e 24h, tração perpendicular, módulo de elasticidade e módulo de resistência. Os tratamentos, em grande parte, atenderam aos requisitos normativos, com três tratamentos atendendo plenamente. Para a maioria das propriedades os fatores de produção não foram significativos do ponto de vista estatístico, possibilitando que possa haver redução de algum fator a fim de manter o mesmo desempenho atendendo aos requisitos normativos.
