An Analysis of Mechanical and Viscoelastic Behaviour of Nano-SiO2 Dispersed Epoxy Composites

Synergistic effect of ZnO and TiO2 nanoparticles on the thermal stability and mechanical properties of glass fiber‐reinforced LY556 epoxy composites

“…Also, NP aggregates resemble microparticles which may act as stress risers causing premature failure of the material upon the application of loads. [30,31] Thus, there is a possible reduction in induced toughening mechanisms within the ZTEG composites when the loading of ZnO-TiO 2 NPs is more than 2 wt%. The toughening mechanisms such as crack deflection, crack blunting, and crack pinning are induced by the addition of NPs.…”

Investigation on curing reaction of phthalonitrile resin with nanosilica and the properties of their glass fiber‐reinforced composites

“…On the other hand, the motion of molecular chains also increased. 12,13,37 Hence, the composites with high content of SiO 2 particles showed decreased T g s. In sum, the stiffness of the composites could be enhanced by addition of SiO 2 particles into BA-ph/CE matrix and the T g s of the composites could be decreased when the high mass fraction of SiO 2 particles was introduced into matrix resin.…”

“…In addition, the agglomeration of SiO 2 in matrix resin would act as stress concentration points in matrix resin and could decrease the bonding between SiO 2 and matrix. 13 Hence, the flexural strength was not effectively enhanced and flexural modulus was decreased with loading of SiO 2 further increased. In sum, the flexural strength (increased 14%) and flexural modulus (increased 33%) of the composite laminates were enhanced via SiO 2 incorporation.…”

“…11 Other researches also indicated that homogeneous dispersion of nano-fillers and nano cluster size in composites could help to improve the interfacial interaction between fillers and matrix to elevate T g of composite. 12,13 Tang et al introduced graphene oxide (GO), which was modified with sulfonated polyarylene ether nitrile (SPEN), into polyarylene ether nitrile (PEN) to prepared SPEN@GO/PEN composite films with improved energy density and low dielectric loss. The films showed potential applications at organic film capacitors.…”

PVP/Highly Dispersed AgNPs Nanofibers Using Ultrasonic-Assisted Electrospinning

“…Additionally, existing studies demonstrate that ultrasound can effectively disperse inorganic nanoparticles in polymer solutions. For example, ultrasound effectively disperses Al 2 O 3 and ZnO nanoparticles in P(VDF-TrFE) [ 43 ] as well as Ag [ 44 ], Al 2 O 3 [ 45 ], TiO 2 [ 46 , 47 ], and SiO 2 [ 48 ] nanoparticles in epoxy resin.…”
