“…globosum. The overall value of changes observed in samples attacked by fungi was twice as large as that presented in the publication of Chung et al (1999); in fact, it was at the similar level as in case of plywood and OSB. Chung's research shows that the aggressiveness of T. viride and A. niger towards particleboards is at the similar level.…”

“…The PB boards used in the present investigations were glued with UF resin, which means that they may be more prone to the decay caused by fungi. Nevertheless, Chung et al (1999) do not provide any information on the type of resin the investigated boards were glued with. Tables 3 to 7 show the mechanical properties of the particleboards subjected to the action of test fungi.…”

This study concerns the influence of selected fungi on changes in physical and mechanical properties of type P2 particleboards intended for use in dry conditions. The tested fungi included Aspergillus niger van Tiehgem, Chaetomium globosum Kunze et Fr., Trichoderma viride Persoon ex S.F., Gray aggr., and Penicillium funiculosum Thom. The incubation process lasted for 16 weeks, yet samples for the strength test were selected after a period of four weeks. The degradation level of boards was estimated by measuring the decrement of initial mass and changes in physicomechanical properties. The obtained results showed that mechanical strength of the investigated boards affected by the tested fungi decreased by 15% to 20%. However, the differences in DSC thermographs indicate that it is cellulose that mainly undergoes degradation in the wood of the investigated boards. Based on the changes in mechanical properties and DSC analyses, we consider T. viride and A. niger as the most aggressive fungal species.

“…Chung et al (1999) gave evidence that resistance of plywood mainly depends on the anatomical characteristics of the wood species used in the wood veneer with a preference of brown and white rot 335respectively for soft-and hardwood. The latter result was not found in this study, but anatomical characteristics or wood species definitely play a role.…”

“…The depletion of durable wood (Tascioglu and Tsunoda 2010) and the shortage of quality timber (Chung et al 1999) necessitate the use of less durable and lesser known wood species as well as the use of engineered wood products. Furthermore, efforts to shift to more low-energy, environmental friendly building materials and the endeavour at minimizing costs (Krüger and Laroca 2010) have also created the search for adopted or new building materials and building concepts with an important role for these engineered products.…”

Decay Resistance of Medium Density Fibreboard (MDF) Made from Pineapple Leaf Fiber

et al. 2015

Abstract. Medium density fiberboard (MDF) production is increasing due to the development of manufacturing technologies. MDF products are utilized for traditional wood applications that require fungal resistance. This study investigated some of the important biodegradation properties of MDF composite board made from renewable biomass from pineapple leaf fiber (Ananas comosus). The variable factors were type of board and type of resin. Two different types of board with a target density of 0.8 g/cm 3 were manufactured. The boards were prepared in three layers of about 1:1:1 weight ratio in crossoriented and unidirectional pattern, using low molecular weight (LM) phenol formaldehyde (PF) resin type PL-3725 and high molecular weight (HM) PF resin type PL-2818 for impregnation and adhesive purposes. Decay resistance (white and brown rot fungi) of the MDF was evaluated to assess its biological performance. In this study, fiber orientation had no effect on the decay resistance to white and brown rot fungi of the specimens. However, a slight increase was found for the mass loss of the low molecular weight PF resin board specimens compared with the mixed low and high molecular PF resin board specimens. The total resin content of 20% of the type I boards prohibits degradation by decay.
