“…The data show that loading of 15 and 30 PHR fillers accompanied by a decrease in the weight fraction of the fibre in the composite played a role in reducing water absorption in the composite. Composites containing ATH 30 PHR filler had the lowest water absorption, which correspond to the findings of other researchers who discovered that the addition of filler to the UP resin could decrease the water absorption properties of the composite [24,25,36]. Nevertheless, other researchers have cautioned that excessive filler loading can result in agglomeration, which produces more voids and leads to higher water absorption.…”

“…The addition of fillers into the UP resin can then help reduce water absorption into the composite. In particular, ATH and CC fillers play an essential role in improving the composite properties against water absorption by adhering to the fibre surface in micro size and resultantly preventing the fibre from absorbing water [24]. The fibre that is originally hydrophilic will become hydrophobic.…”

Gutters made of glass-fibre-reinforced polymer (GFRP) are usually produced with a three-millimetre thickness. The fillers are mixed into unsaturated polyester (UP) resin, which is intended to make the composite material more affordable. This study aims to examine the effects of the addition of alumina trihydrate (ATH), calcium carbonate (CC), and a mixture of ATH and CC of 15 and 30 parts per hundredweight of resins (PHR) on the material properties of the three-millimetre-thick three-layered GFRP composites. The properties observed included physical properties, namely, specific gravity and water absorption, chemical properties such as burning rate, and mechanical properties such as hardness, flexural strength, and toughness. The effects of the fillers on the voids and interfacial bond between the reinforcing fibre and matrix were analysed using the flexural fracture observation through scanning electron microscopy (SEM). The results showed that the addition of fillers into the UP resin led to an increase in the density, hardness, flexural strength, modulus of elasticity, and toughness but a decrease in water absorption and burning rate in a horizontal position. This information can be helpful for manufacturers of gutters made of GFRP in selecting the appropriate constituent materials while considering the technical and economic properties.

In recent years, research has shifted away from conventional materials and alloys to composite materials to create lighter, more efficient materials for specific applications. In order to generate lighter, more efficient materials for specific purposes, research has migrated away from traditional materials and alloys and toward composite materials in current years. Blended microbially nanocomposite that takes advantage of organic flax fibres and nanoreinforced biobased polymers can increase characteristics while keeping the environment in mind. Adding aluminium trihydride (ATH) powder to the natural resin allows it to sustain rigidity without compromising toughness while increasing barrier and mechanical characteristics. Investigation of several composite samples confirmed this positive effect, with systems that contain 10% epoxidized methyl soyate (EMS) and 2.5 wt.% ATH maintains the original resin’s rigidity, strain to fracture, and hygromechanical characteristics while enhancing toughness. Mechanical testing like interlaminar shear strength (ILSS) was found per the standard ASTM testing method. Among the various combinations, the second combinations (77.5 wt.% polyester, 2.5 wt.% ATH, and 20 wt.% of flax fibre) provide the highest value of ILSS (34.31 MPa). Scanning electron microscopy was used to examine the fractured surface of the nanocomposites and the degree of dispersion of the ATH filler.

“…The small range of variations of parameters a and b reveals that the basic property of the epoxy matrix with glass fiber has the dominant role and the fillers either supplement or minimally affect the values when used in small quantities. Atiqah et al, 32 have reported that incorporation of higher wt% of ATH in a polymer matrix improves the distribution and size of pores and this fact can affect the cohesion bonding of fiber and matrix.…”

Multi walled carbon nanotubes and graphene nanoplatelets are novel fillers possessing exceptional intrinsic characteristics, such as high aspect ratio, strength, and good compatibility. These fillers are integrated into a glass fiber reinforced epoxy using a pultrusion process with a mixing ratio of 2:3 to attain the synergetic effect. The electrical and mechanical properties of the composites containing combinations of multi walled carbon nanotubes (0.4 wt%), graphene nanoplatelets (0.6 wt%) and micron aluminum trihydrate (2 wt%) fillers is studied. Significant improvement in electrical and mechanical properties is achieved. This study reveals that the incorporation of hybrid carbon nanofillers into epoxy leads to improved dielectric constant, AC conductivity and mechanical properties as compared with the base epoxy composite with glass reinforcement. The AC conductivity increases from 10−9 to 10−1 S/m and dielectric constant from 3.6 to 100 due to carbon fillers. The mean tensile strength improves from 433 MPa of the base epoxy composite to 508 MPa in carbon‐filled composite. The compressive strength improves from 630 to 681 MPa due to incorporation of carbon fillers signifying the improvement in load transfer effectiveness. The effect of carbon fillers on the flexural strength and hardness is minimal. The experimental data on mechanical parameters have been validated using theoretical modeling and a good correlation is established.
