Solid urban wastes are a primary source of local and global contamination. One approach to slow their accumulation is by using them to obtain addedvalue products. One common example of these waste materials is the fiber from the husks of coconuts, i.e. coir. However, it is also known that microorganisms such as fungi can attack products containing natural fibers. In this respect, this study aimed to evaluate how the mechanical properties of an extruded composite made of 60% recycled HDPE and 40% discarded coir were affected due to accelerated weathering and Phanerochaete chrysosporium attack. The effect of P. chrysosporium on the materials' mechanical properties before and after weathering, using an accelerated weathering (AW) test device, was evaluated by means of tensile and flexural analysis following ASTM standards. Samples were also characterized using Fourier transform infrared spectroscopy (FTIR) and scanning electron microscopy (SEM). FTIR spectroscopy and SEM showed that both types of treatment degraded the surfaces of the tested samples. However, the mechanical performance was not seriously affected, which means that other fungal species would affect the composites to a lesser extent.

“…Two types of spectra were obtained that include low-resolution spectra from 0 to 1,100 eV binding energy to determine elemental composition (O and C ratios) and high-resolution spectra from 280 to 300 eV to analyze C. For the quantitative analysis, the spectra were baseline corrected, normalized, and curve fit using IGOR Pro 5.05 software (WaveMetrics, Inc.). The area of each peak identified by curve fitting was mathematically computed (Fabiyi et al 2009). The following data processing restrictions were made: (1) the full widths at half height (FWHM), for C1 (C-C or C-H), C2 (C-O), C3 (C=O or O-C-O), and C4 (O-C=O) peaks (285, 286.5, 288, and 289.5 eV) were kept constant (1.6 eV); (2) the fitted peaks were made using Voigt; (3) the third restriction is that a peak C0 (C=C), at 283.5 eV, was fitted when the residual of the band indicating the presence of this peak (FWHM of 1.6 EV); and (4) therefore, with these restrictions in place, a peak-fitting routine was then used to minimize and randomize the residual signal.…”

A procedure for rapidly modifying beech wood using a thermally initiated solvent-free grafting system was examined. In the modification, butyl acrylate and butyl methacrylate were used as vinyl monomers. Free radicals were generated from 2,2 0 -azobis(2-methylpropionitrile) or benzoyl peroxide at 103 and 180°C by contact heating of the modified material. Chemical changes in the material were investigated by FTIR and X-ray photoelectron spectroscopies. The modification resulted in decreased surface wetting of the material manifested by increased water contact angles. The hardness of the resultant material decreased, while its color changed by the effect of temperature. It was shown that the approach allowed for efficient thermal-initiated modification of wood with rapid contact heating.

“…These materials can be used in indoor and outdoor applications, including windows and doorframes, interior panels in cars, railings, decking, cladding and fences [4]. Its dimensional stability tends to be better than that of the traditional wood products, thereby rendering them suitable for application in end-uses in humid and water front environments [5]. Furthermore, several companies are using wood plastic composites because of the increased stability and resistance to biological attack compared to traditional wood and solid lumber products [6].…”

Effect of natural ageing on the properties of recycled polypropylene/ethylene vinyl acetate/wood flour composites

et al. 2017

Wood flour composites main applications are represented by outdoor furnishing. Therefore, it is important to evaluate their behavior under natural ageing conditions. This work aims to investigate the natural ageing impact on the mechanical, physical, thermal e morphological properties of recycled polypropylene/ethylene vinyl acetate/wood flour composites (PP/EVA/ITA). Samples were exposed to natural ageing for 12 months in Porto Alegre (BR). Mezilaurus itauba (ITA) wood flour was used at 30 % w/w. Results showed that PP filled wood flour retained a higher fraction of the original mechanical properties after natural ageing. Crystallinity degree for composites increased from 30.9 up to 37.5% Climatic conditions affected the colorimetric and morphological characteristics of composites, indicating that there was not only photo-degradation but also thermo-oxidative and hydrolytic degradation. In this way, the use of antioxidant additives and UV photo-absorbers is recommended to avoid stress-cracking, discoloration and loss the mechanical properties.
