“…The room temperature mechanical properties’ improvement correlates well with the results by other authors, who have reported basalt fiber reinforcement in the range of 25–40% [ 37 ]. Furthermore, the effect of the temperature on the composites has been discussed, but the morphologies of the samples in those works have been very different from those of ours, and thus the relevant conclusions cannot be transposed.…”

The Effect of Prestressing and Temperature on Tensile Strength of Basalt Fiber-Reinforced Plywood

et al. 2021

The reinforcement of plywood is demonstrated by laminating pretensioned basalt fibers between veneer sheets, to fabricate so-called prestressed plywood. Belt type basalt fibers bearing a specific adhesion promoting silane sizing were aligned between veneer sheets with 20 mm spacing and were pretensioned at 150 N. Three-layer plywood samples were prepared and tested for tensile strength at room temperature and at 150 °C. The room temperature tensile tests revealed a 35% increase in tensile strength for prestressed plywood compared to that of the conventional specimen. The reinforcement effect deteriorated at 150 °C but was restored upon cooling to room temperature. The deterioration is attributed to the weakening of bonding between the basalt fibers and phenolic resin matrix at elevated temperatures due to the softening of the resin.

“…A higher degree of crystallization results in higher mechanical properties, this relationship was also confirmed in this study. Another very important feature of polymeric materials is their water absorption and changes in properties triggered by the ageing process, which may include, e.g., self-stress relaxation, recrystallization, phase dispersion in multicomponent systems, softener migration, the formation of stress and fatigue cracks, thermo-oxidative degradation, or evaporation or migration of volatile components [47,48]. All these effects affect mechanical properties.…”

The aim of this study was to evaluate the changes in physical-mechanical properties of the samples manufactured by 3D printing technology with the addition of varying degrees of polylactide (PLA) infill (50, 70, 85 and 100%). Half of the samples were soaked in physiological saline. The material used for the study was neat PLA, which was examined in terms of hydrolytic degradation, crystallization, mechanical strength, variability of properties at elevated temperatures, and dissipation of mechanical energy depending on the performed treatment. A significant impact of the amount of infill on changeable mechanical properties, such as hydrolytic degradation and crystallization was observed. The FDM printing method allows for waste–free production of light weight unit products with constant specyfic strength.

“…For this reason, the development of composites with BioPE polymeric matrix is of great importance, due to the potential for technological application and the reduction of environmental impacts [18]. There are works in the literature on polyethylene composites reinforced with jute [19,20], curauá [21], sisal [22,23], coconut ber [24,25], cotton [26], rice husk [27] and wood powder [28,29], suggesting good mechanical properties.…”

From Waste to Reuse: Manufacture of Ecological Composites Based on Biopolyethylene/wood Powder with PE-g-MA and Macaíba Oil

et al. 2021

This work aimed to investigate the biopolyethylene (BioPE)/wood powder (WP) composites compatibilized with polyethylene-grafted maleic anhydride (PE-g-MA), using macaíba oil (OM) as a processing aid. The composites were prepared, initially, in an internal mixer and, later, the crushed akes were molded by injection. Mechanical properties (impact, tensile, exural and Shore D hardness), heat de ection temperature (HDT), Vicat softening temperature, differential scanning calorimetry (DSC), thermogravimetry (TG), water absorption, torque rheometry and scanning electron microscopy (SEM) were evaluated. The addition of 30% wood powder to the BioPE matrix increased the elastic modulus (tensile and exural), Shore D hardness and heat de ection temperature (HDT), compared to neat BioPE. These properties were improved when 10% of the PE-g-MA compatibilizer was added, compared to neat BioPE and the non-compatibilized composite. There was a signi cant reduction in the torque of the composites with the addition of macaíba oil, indicating that it improved the processability. In addition, the incorporation of macaíba oil into the composites helped to reduce water absorption, as well as to increase impact strength. SEM micrographs illustrated a greater degree of interfacial adhesion when PEg-MA and macaiba oil were added.
