“…As illustrated in Figure 6(a), impact tests were performed according to the ASTM D 4812 [13,14] and ISO 180 [15] code using a universal impact machine (QPI-IC-21J). The impact test can be used to differentiate different materials based on overall toughness values.…”

“…The toughness of Glass fibre-reinforced polymer Micro and Nanofiller Composites is tested using the impact test for an un-notched cantilever beam [13]. It is seen that with the addition of Multiwall Carbon Nanotube to the epoxy matrix, the toughness increases [14]. It is prevalent for cellulosic materials to be used as fibre content for natural composites.…”

A novel combination of Borassus Flabellifer Petiole Fibre/Palmyra Palm Petiole Fibre (PP) and Borassus Flabellifer Leaf Stalk Fibre/Palmyra Palm Leaf Stalk Fibre fibres (LS) bonded by vinyl ester is considered as the natural fibre-reinforced hybrid composites. Three-layered composites with various stacking sequences at 30 wt.% fibre loading were studied. Tensile, impact, and hardness properties exhibit increasing trend for different stacking sequences. A maximum increase of 215.8% tensile strength and 310.5% impact strength was observed in the PPLSPP (90/0/90) specimen. The water absorption percentage showed a peak value of 18% and the hardness enhancement was around 75% for the LSPPLS (90/0/90) sample. The Fourier Transform Infrared spectroscopy was performed and Scanning electron micrographs were performed to show the fibre–matrix bonding.

“…In Glass Reinforced Epoxy (GRE), incorporating Multi-wall carbon nanotubes (MWCNT) and Silica (SiO2) nanoparticles at various weight ratios revealed that GRE achieved its highest ultimate strength with 0.1 wt% MWCNT and 1 wt% SiO2. Similarly, the highest Young's modulus was observed in GRE containing 0.2 wt% MWCNT and 2 wt% SiO2 [10,11]. Incorporating filler additives such as CaCO3, Al2O3, MgO, and CuO in epoxy-based glass fiber composites substantially enhances tensile, flexural, and impact strength.…”

A revolutionary composite material, blending Glass Fiber Reinforced Polymer (GFRP) with advanced nanofillers like TiO2 and MgO, showcases remarkable versatility in various industries due to its unique properties. The process involves precise control of key factors, including fiber stacking sequence (F.S.S) and nanofiller integration (MgO and TiO2). The vacuum bagging process is employed in the production of nanocomposite laminates. Experimental studies have been conducted to assess the performance of composites with and without nanofillers, with a specific focus on crucial mechanical properties, namely ultimate tensile strength (U.T.S), flexural strength (F.S), impact strength (I.S), and hardness (H). The Taguchi L9 orthogonal array design optimizes parameters and enhances mechanical properties. Comparisons reveal significant improvements with nanofillers, including a 31.96% increase in ultimate tensile strength and a substantial 68.43% enhancement in flexural strength. ANOVA results highlight the critical impact of fiber stacking sequence on ultimate tensile strength (63.65%), flexural strength (65.70%), and impact strength (9.30%), while nanofillers play a lesser role, contributing 11.71% to ultimate tensile strength, 2.66% to flexural strength, and 3.61% to impact strength. Notably, in composite hardness, nanofillers play a more significant role, contributing 39.22%, while the influence of fiber stacking sequence is lower at 3.29%.

“…An increase in filler concentration of more than 3% resulted in a decrease in the tensile modulus. The effect of adding filler to the composite was also investigated by Sravanthi et al [58] by performing impact testing on GFRP with added micro carbon filler. Bidirectional glass fiber is arranged in 5 layers with 5, 10, and 15 wt% filler variations with a hand lay-up manufacturing process.…”

The Interconnection of Carbon Active Addition on Mechanical Properties of Hybrid Agel/Glass Fiber-Reinforced Green Composite

Nowadays, the hybridization of natural and glass fiber has promised several advantages as a green composite. Nevertheless, their different characteristics lead to poor mechanical bonding. In this work, agel fiber and glass fiber was used as reinforcements, and activated carbon filler was added to the polymer matrix of a hybrid composite to modify its characteristics and mechanical properties. A tensile and bending test was conducted to evaluate the effect of three different weight percentages of activated carbon filler (1, 2, and 4 wt%). Vacuum-assisted resin infusion was used to manufacture the hybrid composite to obtain the high-quality composite. The results have revealed that adding 1 wt% filler yielded the most optimum result with the highest tensile strength, flexural strength, and elastic modulus, respectively: 112.90 MPa, 85.26 MPa, and 1.80 GPa. A higher weight percentage of activated carbon filler on the composite reduced its mechanical properties. The lowest test value was shown by the composite with 4 wt%. The micrograph observations have proven that the 4 wt% composite formed agglomeration filler that can induce stress concentration and reduce its mechanical performance. Adding 1 wt% filler offered the best dispersion in the matrix, which can enhance better load transfer capability.
