“…Abundantly available plants cultivated in agriculture might be good candidates, showing also anatomical and chemical structures suitable to produce panels (Mati-Baouche et al, 2014;Papadopoulou et al, 2015). Different researchers have reported the utilization of agricultural wastes in particleboards production, such as sugarcane bagasse (Mendes et al, 2012), rice husk (Melo et al, 2009), maize cob (Scatolino et al, 2013;Scatolino et al, 2015;Sekaluvu;Tumutegyereize;Kiggundu, 2014), coffee husk (Mendes et al, 2010), peanut husk (Guler; Buyuksari 2011), corn straw (Silva et al, 2015), vine (Vitis vinifera L.) (Yeniocak et al, 2014) and castor husk (Silva et al, 2016).…”

The wood panel industry is constantly growing, being necessary the innovation in technologies and raw materials to improve the quality of the final product. Considering the shortage and pressure to decrease the dependence of wood, there is an interest in other renewable materials such as agricultural wastes. Among these wastes, coffee parchment is one which deserves notoriety. An alternative use for coffee parchment could be for production of particleboard in association with wood particles. This study aimed to evaluate the feasibility of using coffee parchment for production of particleboard. The following percentages of wastes were used: 0, 10, 20, 30, 40 and 50% in association to eucalyptus wood. The panels were produced with 8% of urea formaldehyde (based on dry weight of particles). The pressing cycle consisted by: pre-pressing of 0.5 MPa for 10 minutes followed by pressing of 4.0 MPa, and temperature of 160° C for 15 minutes. The compaction ratio of particleboards produced using higher quantities of parchment improved the physical properties. The properties of Water Absorption (2 and 24 h) and Thickness Swelling (2 h) decreased with increasing percentage of coffee parchment. The Thickness Swelling (24 h) showed not significant effect with an increase of coffee waste. The Modulus of Elasticity for coffee parchment particleboards was in the range 646.49 ± 112.65 to 402.03 ± 66.24 MPa, while the Modulus of Rupture ranged from 8.18 ± 1.39 to 4.45 ± 0.75 MPa. The results showed that 10% of coffee parchment could be added for production of particleboards.Index terms: Agricultural waste; lignocellulosic material; renewable material. RESUMOA indústria de painéis de madeira vem em constante crescimento, sendo necessária a inovação em tecnologias e matéria-prima para melhorar a qualidade do produto final. Considerando a escassez e pressão na diminuição da dependência por madeira, existe um interesse em outros materiais renováveis, como os resíduos agrícolas. Entre esses resíduos, o pergaminho de café merece destaque. Uma alternativa para utilização do pergaminho de café poderia ser na produção de particulados, em associação com partículas de madeira. O objetivo deste trabalho foi avaliar a viabilidade de utilização do pergaminho de café para produção de aglomerados. As porcentagens de resíduo utilizadas foram: 0, 10, 20, 30, 40 e 50% em associação com madeira de eucalipto. Os painéis foram produzidos com 8% de uréia-formaldeído (base massa seca de partículas). O ciclo de prensagem consistiu de: pré-prensagem de 0,5 MPa por 10 minutos, seguido por prensagem de 4,0 MPa e temperatura de 160° C por 15 minutos. A razão de compactação dos painéis produzidos com maiores quantidades de pergaminho melhorou as propriedades físicas. As propriedades de absorção de água (2 e 24 h) e inchamento em espessura (2 h) diminuíram com o aumento da porcentagem de pergaminho de café. O inchamento em espessura (24 h) não apresentou diferenças significativas com o aumento de resíduo de café. O Módulo de Elasticidade dos painéis vari...

“…Reinforcement of kenaf fiber with polymers such as the reinforcement of kenaf with unsaturated polyester, kenaf with polypropylene and kenaf reinforced epoxy have been widely presented by researchers [6][7][8][9][10][11]. Nonetheless, the usage of kenaf fiber for various applications such as in the automotive, construction and sports fields have only started to get the attention of many researchers, and the trend is increasing according to market demand [12,13]. A study on the effect of various kenaf fiber content on its mechanical properties may increase the demand of kenaf fibers, especially in Malaysia.…”

Kenaf fiber has been cultivated as an industrial crop. In this paper, we present the ongoing works of an assessment on the mechanical properties of its fiber composites. Tensile, flexural and impact tests were executed on untreated short kenaf fiber reinforced epoxy composites. Its fiber content is varied from 5% up to 20%, and was compared to neat epoxy (NEAT). Using a hand lay-up technique, a mixture of kenaf fiber and epoxy is poured into a mould and left to dry at room temperature for 24 hours. Seven specimens were cut according to ASTM D3039, ASTM D790 and ASTM D256 for the tensile test, flexural test and impact test, respectively. The results showed that the tensile, flexural and impact strengths of the kenaf fiber are lower compared to NEAT. Samples at 5% kenaf fiber content shows the highest tensile strength, flexural strength and impact strength at 27. 1 MPa and 18.2 MPa and 0.56 kJ/m2, respectively. The 5% fiber content was finalized as the fiber content that can be applied in archery.
