Effect of functionalized metal oxides addition on the mechanical, thermal and swelling behaviour of polyester/jute composites

Influence of ZrO2 Incorporation on Sisal Fiber Reinforced Unsaturated Polyester Composites

“…Figure illustrated that the Izod impact energy (or toughness) was increased with the increment of filler loading for all types of UP‐based composites from 5 to 35 wt%. When the loading increases from 35 to 45 wt%, the ability of the matrix to absorb energy (which was mentioned here as impact energy) reduce due to irregular dispersion and agglomeration of the fillers which results in the decrement of the absorbed energy as well as the toughness . It was observed from Fig.…”

“…The fillers delay the crack initiation and thereby propagation that results in the increment of flexural strength with increasing filler loading and that is subsequent from 5 to 35 wt% filler loading. Another cause for the increment may be the crack trapping and pinning by the micron size ZrO 2 particles . The reasons behind the decrement in flexural strength beyond 35 wt% filler content may be due to the agglomeration and irregularity in the dispersion of the fillers within the matrix.…”

“…It can be observed that with an increase in the filler (CaCO 3 and MgO) percentage within UP, properties such as tensile modulus, bending modulus, and microhardness improves significantly. The UP reinforced by jute fiber along with ZrO 2 or Al 2 O 3 particles showed significant improvement in the properties of the matrix polymer and an optimum results had been obtained for UP/Jute/ZrO 2 composites . Sisal fiber, red mud, and glass fiber hybrid composites have been investigated.…”

Quantification of nanoparticle dispersion within polymer matrix using gap statistics

“…In this study, two composites were plates manufactured from using titanium (IV) oxide nanoparticles (21 nm) and the silane coupling agent, 3-aminopropyltrimethoxysilane (APTMS), all acquired from Sigma Aldrich. Silane functionalization was conducted by mixing a solution of 95% methanol, 5% distilled water and 1% silane before the addition TiO 2 nanoparticle and heating at 95°C to ensure complete evaporation of the alcohol [49]. The mixture was dried at 100°C for 1 h and then crushed before dispersing via mechanical stirring within an epoxy matrix at a fraction weight of 2 wt%.…”

Critical Review of the Parameters Affecting the Effectiveness of Moisture Absorption Treatments Used for Natural Composites

“…The incorporation of metal oxide particles into the structure of natural composites improves their moisture absorption and swelling properties. This behavior is attributed to the good capability of hydrophobic metal oxides to bond with hydrophobic polymers [285]. Reinforcing kenaf fibers composites with magnetite particles offers dual-functional properties such as paramagnetic and electromagnetic shielding functions in addition to moisture absorption resistance [286].…”
