“…Furthermore, the manufacturing process of BFs is similar to that of glass fibers. BFs have been used within studies as reinforcements in thermoplastic matrices in the last years [15,16]; however, the usage in WPCs as reinforcement was rarely reported. Chen et al [17] added BFs into a commercial WPC.…”

The main aim of this study was to investigate the effect of basalt fiber (BF) reinforcement in wood–plastic composites (WPCs). Basalt/wood hybrid composites based on polypropylene (PP) were prepared with different percentages of the reinforcement (the total fiber content was 10 wt%, 15 wt%, and 20 wt%). The BCS17-6.4-KV16 chopped basalt fibers with nominal diameter of 17 μm, cutting length of 6.4 mm, and wood fibers—Lignocel C 120 with the particle size of 70–150 µm—were used as a reinforcement. Composites were produced by the injection molding method. The density of the produced composites and their processing properties such as Vicat softening point and shrinkage were determined. In addition, the thermal expansion behavior of filled plastic composites was investigated. Mechanical tests were subsequently performed to evaluate the tensile, flexural, and impact properties at various temperatures (i.e., at −24 °C, 23 °C, and 80 °C) and after soaking in water. Scanning electron microscopy images were acquired to assess the effects of reinforcement and homogenization of mixtures and to determine the characteristics of the microstructure. The results showed that the hybridization process improved the tensile and flexural properties of reinforced wood composites. Moreover, the incorporation of high-strength basalt fibers into the composite led to increased stiffness. Even a small addition of 10 wt% total fibers led to a significant decrease in shrinkage and coefficient of thermal expansion.

“…The standard deviation for the blend containing PE-g-MA at 2.5 is also lower when compared to the blend containing PE-g-MA at 5.0. Prajapati et al (2017) carried out a study using PE-g-MA as a coupling agent in composites of PA6 reinforced with basalt fiber and verified that the MP obtained by tensile and impact testing have improved and relatively remain stable when the PE-g-MA is incorporated to the composites at 3 to 5 wt%. Thus, the results of Prajapati et al (2017) as well as the results of this present study lead to the conclusion that the PE-g-MA incorporated at ~3 wt% in blends or composites of PA6 is effective for the compatibilization of these materials.…”

Polymeric wastes have caused increasing environmental problems, mainly in oceans that accumulate large amounts of non-degradable plastic waste. Particularly, waste of polymeric multilayer films for packaging presents low interest for mechanical recycling due to the poor properties and low commercial value of the recycled material generated as polymeric blends. Multilayer films of low-density polyethylene (LDPE) and polyamide 6 (PA6) is a typical material used for packaging applications. The aim of this study was to evaluate the action of the concentration of maleic anhydride grafted polyethylene (PE- g-MA) on the compatibilization of LDPE/PA6 blends generated from mechanical recycling of multilayer films containing both polymers. The action of the PE- g-MA on the properties of the LDPE/PA6 blends was evaluated by tensile tests, optical microscopy, melt flow rate, and scanning electron microscopy. The use of PE- g-MA at 2.5 wt% as a compatibilizer during reactive extrusion of the multilayer films waste has showed the best result for production of the respective recycled LDPE/PA6 blends.

“…Thus concluded that maleic anhydride helps in enhancing the interaction between the BF and PP. Prajapati et al [ 10 ] reinforced nylon with BF and concluded that the coupling agent modified composites had better mechanical properties. Enhanced interfacial adhesion and reduced fiber breaking increased the properties of the composites.…”

Natural mineral fiber basalt has excellent thermal and mechanical characteristics. The current research focuses on evaluating the mechanical and thermal characteristics of polypropylene (PP) composites reinforced with short-length basalt fibers (BF) fabricated by the melt mixing method. Maleic anhydride (MAH) at 3 wt% was used as a compatibilizer for fabricating the composites. The composite's mechanical, thermal, and morphological properties were investigated. The mechanical properties of the composites were enhanced with an increase in BF loadings from 10 to 40 wt% and beyond that it decreased.The chemical interaction between the fiber and the matrix was evaluated using Fourier transform infrared spectroscopy. Differential scanning calorimetry studies were used to determine the crystallization temperature, melting temperature and percent crystallinity of the composite. According to dynamic mechanical analysis, reinforcing PP with BF improved the damping property.Scanning electron microscopy revealed good interfacial interaction among the fiber and matrix and X-ray diffraction was used to study the composite crystallinity.
