Influence of nano-SiO2 and carbon fibers on the mechanical properties of POM composites

Viscoelastic behaviour and fracture toughness of linear-low-density polyethylene reinforced with synthetic boehmite alumina nanoparticles

“…A large body of research has been developed on polar nanofillers (such as silicas, metal oxides, metal salts, layered silicates, etc.) which have been successfully added to thermoplastic matrices in order to improve their thermal, mechanical and rheological performances [1][2][3][4][5][6][7][8]. On the other hand, these nanofillers are generally poorly dispersed in apolar thermoplastics (such as polyolefins), thus limiting the beneficial effects of nanofiller addition on the thermo-mechanical properties.…”

Nanocomposites of Polyoxymethylene

“…In other work, nanosilica was introduced into polyoxymethylene/ carbon fi ber (POM/CF) composites producing a synergic improvement of their mechanical properties. At a content of 1-5 vol%, the nano-SiO 2 exerted an obvious reinforcing eff ect on POM, leading to an increase in the elastic modulus and stiff ness of the composites [24]. Application of some nanoparticulate fi llers was showed to cause simultaneous increase of tensile strength and impact strength at low fi ller content.…”

“…Polyoxymethylene/carbon fi ber (POM/CF) composites containing nano-SiO 2 were prepared, and the nano-SiO 2 exerted an obvious reinforcing eff ect on POM at the content of 1-5 vol%, leading to an increase in the elastic modulus and stiff ness of the composites [24]. It was explained that nanosilica particles when uniformly distributed on the sized fi ber surface through the emulsion act as stress concentrators at the interface, assist in holding back the excessive stress spreading in a fl aw and in changing the crack propagation paths.…”

Polyoxymethylene/silica/polylactic acid-grafted polyethylene glycol nanocomposites: structure, morphology, and mechanical properties and ozone and UV durability

“…Various nanollers have been examined for the preparation of POMbased nanocomposites, including nanosilica (NS), [4][5][6] carbon nanotubes, 7-9 montmorillonite, [10][11][12][13][14] CaCO 3 , 15 graphite, 16 Al 2 O 3 , 17 ZnO, 18 hydroxyapatite, 19,20 boehmite alumina, 14,21 polyhedral oligomeric silsesquioxane, 22,23 and NS and carbon bers. 24 POM can also been combined with ethylene-octene copolymer to improve the relaxation properties of POM. 25 These results show that the presence of nanoadditives in POM matrix can enhance its mechanical properties, hardness, and thermal stability.…”
