“…Nevertheless, up to now, lots of efforts have been devoted to further improvement of the mechanical strength of POM by means of incorporation with fillers such as calcium carbonate, talc, diatomite, clay, and glass fibres. Several authors reported that due to addition of glass fibre the heat deflection temperature of POM was found to increase about 20-40 ∘ C [6][7][8]. Addition of glass fibre with POM increases the mechanical and thermal properties with 25% ratio.…”

Polyoxymethylene is a material which has excellent mechanical properties similar to Nylon-6 filled with 30% GF. 75% POM and 25% glass fibre (POMGF) were blended with nanoclay to increase the tensile and flexural properties. Samples were extruded in twin screw extruder to blend POMGF and (1%, 3%, and 5%) Cloisite 25A nanoclay and specimens were prepared by injection moulding process. The tensile properties, flexural properties, impact strength, and hardness were investigated for the nanocomposites. The fibre pull-outs, fibre matrix adhesion, and cracks in composites were investigated by using scanning electron microscopy. 1% POMGF nanocomposite has low water absorption property. Addition of nanoclay improves the mechanical properties and thermal properties marginally. Improper blending of glass fibre and nanoclay gives low tensile strength and impact strength. SEM image shows the mixing of glass fibre and nanoclay among which 1% POMGF nanocomposite shows better properties compared to others. The thermal stability decreased marginally only with the addition of nanoclay.

“…The polyacetal copolymers show high heat stability and a longterm mechanical and physical properties, although they have lower crystallinity and lower short-term mechanical strength in comparison with polyacetal homopolymers [3,4]. For these beneficial properties, they have been applied to replace metals and ceramics in microelectronic packaging, aerospace, automotive, and biomedical applications [1,5,6].…”

In this work the influence of molecular weight of three polyoxymethylene (POM) copolymers on the properties of (POM)/hydroxyapatite (HAp) nanocomposites for long-term bone implants have been investigated by various physicochemical methods. Electron microscopy observations confirmed uniform dispersion of HAp in the polymer matrix, whereby DSC results show that HAp influences the degree of crystallinity of POM matrix. Temperature modulated differential scanning calorimetry (TMDSC) was applied to study the melting and recrystallization processes of POM matrix-it was found that with decreasing of POM molecular weight the amout of reversible melting increases. WAXD results show no shift in 2θ for pure POM copolymers and all POM/hydroxyapatite nanocomposites, indicating that the addition of HAp does not change the hexagonal system of POM. For all three copolymers, Young's modulus increases with increasing hydroxyapatite concentration, whereby elongation at break decreases. On the contrast, HAp concentration does not have a significant influence on the tensile strength.

“…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 obtained from formaldehyde by homopolymerisation (POM-H) or copolymerization with cyclic ethers (POM-C).…”

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.
