“…It should be also considered the additional possibility of increasing the adhesion of glass fibers to the polyoxymethylene matrix, e.g., by adding silane media, which contains active functional groups enabling chemical connection between the components. Silane compounding agents are widely used not only in the case of thermoplastic polymer composites but also in the case of thermosets reinforced with fibers [38][39][40]. Another option is to prepare the surface of the fiber to strengthen the mechanical adhesion, or if the injection process molding is being considered, the alternative is to control the process of shrinkage (increasing the content of the crystalline phase) to provide a better mechanical connection between the components.…”

The paper evaluated the possibility of potential reinforcing of poly(oxymethylene) (POM) by glass fiber and the influence of fiberglass addition on mechanical properties under dynamic load. Four types of composites with glass fiber and another four with carbon fiber were produced. The fiber content ranged from 5% to 40% by weight. In the experimental part, the basic mechanical and fatigue properties of POM-based composites were determined. The impact of water absorption was also investigated. The influence of fiber geometry on the mechanical behavior of fiber-reinforced composites of various diameters was determined. To refer to the effects of reinforcement and determine the features of the structure scanning electron microscopy images were taken. The results showed that the addition of up to 10 wt %. fiberglass increases the tensile properties and impact strength more than twice, the ability to absorb energy also increases in relation to neat poly(oxymethylene). Fiber geometry also has a significant impact on the mechanical properties. The study of the mechanical properties at dynamic loads over time suggests that composites filled with a smaller fiber diameter have better fatigue properties.as well as heating fabrics powered by electricity [2][3][4][5]. Many scientific papers present the advantages of introducing carbon fibers to thermoplastic materials. Carbon fibers are not only lightweight or provide very good strength properties, but also have a positive effect on tribological properties, and therefore they also can be successfully used as a reinforcement in ceramic matrices [6][7][8][9][10][11][12][13][14][15][16][17].Carbon fibers are not only one fiber introduced in composites which provide good mechanical properties. Currently, about 60% of produced glass fibers are applied to make composites on polymeric matrices, even though they have insignificantly lower physical and mechanical properties than carbon fibers. Glass fibers are characterized by low elongation and high modulus of elasticity. Attention should be paid to good dielectric properties, namely the fibers have low values of relative permittivity and dielectric loss factor. A valuable advantage of glass fibers is the very good wettability of the polymers, and hence the possibility of forming a strong bond at the polymer/glass interface. The mechanical properties of fiber-reinforced composites improve as the length of reinforcing fibers increase, while the strength of a single glass fiber depends on its diameter. If the fiber diameter is larger, there is a higher probability of material defects and damages describe in literature as micronotches and microcracks [18].Many groups of researchers conduct research on polymer composites with glass fiber. It has been revealed that glass fibers successfully strengthen polymers causing better strength properties, higher resistance to creep, and fatigue, as well as provide greater dimensional stability [19][20][21][22].POM is a thermoplastic material with a high degree of crystallinity. This polymer is obta...

“…8 Natural mineral materials can be used as an alternative due to their unique surface and porous structure. [9][10][11] The mineral nanobers acquired from natural minerals as raw materials have the advantages of small investment, low cost, and small environmental load.

“…This issue has been ascribed to the difference in hydrophobicity between the polymers and the plant derived fillers [38][39][40]. Therefore, to achieve adequate performance, it is essential to carry out a filler surface pretreatment [41] or use a coupling agent [42] to ensure an enhanced adhesion with the polymer matrix. Furthermore, the modification of the natural fillers can also influence some characteristics such as their hydrophobicity and porosity [43].…”

Evaluation of Different Compatibilization Strategies to Improve the Performance of Injection-Molded Green Composite Pieces Made of Polylactide Reinforced with Short Flaxseed Fibers

Green composites made of polylactide (PLA) and short flaxseed fibers (FFs) at 20 wt % were successfully compounded by twin-screw extrusion (TSE) and subsequently shaped into pieces by injection molding. The linen waste derived FFs were subjected to an alkalization pretreatment to remove impurities, improve the fiber surface quality, and make the fibers more hydrophobic. The alkali-pretreated FFs successfully reinforced PLA, leading to green composite pieces with higher mechanical strength. However, the pieces also showed lower ductility and toughness and the lignocellulosic fibers easily detached during fracture due to the absence or low interfacial adhesion with the biopolyester matrix. Therefore, four different compatibilization strategies were carried out to enhance the fiber–matrix interfacial adhesion. These routes consisted on the silanization of the alkalized FFs with a glycidyl silane, namely (3-glycidyloxypropyl) trimethoxysilane (GPTMS), and the reactive extrusion (REX) with three compatibilizers, namely a multi-functional epoxy-based styrene-acrylic oligomer (ESAO), a random copolymer of poly(styrene-co-glycidyl methacrylate) (PS-co-GMA), and maleinized linseed oil (MLO). The results showed that all the here-tested compatibilizers improved mechanical strength, ductility, and toughness as well as the thermal stability and thermomechanical properties of the green composite pieces. The highest interfacial adhesion was observed in the green composite pieces containing the silanized fibers. Interestingly, PS-co-GMA and, more intensely, ESAO yielded the pieces with the highest mechanical performance due to the higher reactivity of these additives with both composite components and their chain-extension action, whereas MLO led to the most ductile pieces due to its secondary role as plasticizer for PLA.
