“…The higher impact strength is subject to several factors such as constituents, the strength of interlinking bond between the fibers and matrix. [22][23][24] From Figure 7A, hybrid laminates composed of three successive layers of RF (GR 3 ) exhibited 12.6% higher impact strength compared to the hybrid laminate composed of AF (GA 3 ) layers. The influence of AF in reducing the impact strength was noticeable with hybrid laminates composed of at least one layer of AF in the stacking sequence.…”

Environment friendly polymer composites made of plant based natural fibers such as bamboo fiber, roselle fiber (RF), aloe vera fiber (AF) oil, or kenaf fiber are cardinal of the current world toward sustainability. They offer lower carbon footprint, higher biodegradability, higher specific strength, higher thermal, and acoustic characteristics. On the other hand, properties of synthetic glass fibers (GFs) such as high specific strength to weight ratio, great resistance during impact, and high durability extend their application perspective for various engineering materials. As such, in the present study, mechanical properties and thermal stability of hybrid laminate comprising of natural fiber (i.e., AF and RF) and synthetic fiber (i.e., GF) fabricated using hand layup process were investigated. Experimental findings reveal that sequencing of the fibers significantly affects properties of the composite. Introducing a layer of AF between RF increased the tensile strength by 30.2% respectively while hybrid laminates composed of three successive layers of RF exhibited 12.6% higher impact strength compared to hybrid laminate composed of AF. Besides, the thermal stability of hybrid laminates was higher (i.e., minimal weight loss of <6.1% when heated up to 800°) compared to neat polymer or laminates with single reinforcement. The enhanced thermal stability, mechanical properties, and tribological properties of the “greener” hybrid laminates can be employed in various structural or lightweight industrial applications.Highlights Hybridization using natural fibers and synthetic fibers are attempted and investigated. Fiber sequencing significantly affects mechanical properties of the composite. Higher thermal stability of hybrid laminates, that is, minimal weight loss of <6.1% when heated up to 800°. Laminated composed of AF in between RF exhibited lowest frictional coefficient. “Green” hybrid polymer laminate suitable for various structural and lightweight industrial applications is identified.

“…For this particular work, glass fibre varieties C, E, and S are utilised. C-type glass fibres have enhanced chemical corrosion resistance [22], E-type glass fibres have good insulation against electricity [23,24], and S-type glass fibre has good strength attributes [25,26]. Silicon is the primary component of glass fibre, and the efficacy of the fibres will vary depending on the addition of other elements.…”

Various peel-off experiments can be used to determine the adhesion strength of various fibres. Among them was the "T" type peel-off test, which measures the adhesions between fibres. The use of organic and inorganic fillers in flake or powder form will alter the adhesive properties of the binders as well as the adhesive strength between the fibres. In this study, the adhesion strength between three different varieties of glass fibres (C-Glass, E-Glass, and S-Glass fibres) with a PLA core has been investigated. As a binder, an epoxy resin was used, and the resin was modified with inorganic additives such as alumina, bentonite, and silicon carbide. Peel-off testing was used to examine the effect of additives on the bonding strength between a thermoplastic core and a synthetic fibre. The addition of inorganic compounds was found to reduce the adhesion strength between the fibres and the core. In order to evaluate the initial adhesion between the filaments and the core, nine specimens were fabricated without the addition of any additives and their strengths were determined. Maximum adhesion strength of 71.8 MPa was recorded for the neat resin. The adhesive strength after inclusion of additives was observed to decrease by 18.14%, and recorded maximum peel-off strength of 58.2 MPa. Also, the inclusion percentages of the additives were found to be the most influential factor in determining the composites' adhesive properties. Validation tests were also conducted with the optimized results which demonstrated that the predicted and experimental results were in excellent agreement. Macro and micro approaches were employed to analyze the deformation mechanisms in order to gain a comprehensive understanding of how the additives affected the adhesion strength.

Polyphenylene sulfide (PPS) is a semicrystalline thermoplastic which can pass UL94V-0 standard without adding flame retardant. In the present study, effect of alumina (Al 2 O 3 ) addition on the mechanical, tribological, and acoustical behavior of PPS polymer were investigated. Experimental findings indicate that elastic modulus, tensile strength, and flexural strength were enhanced by 21.4%, 7.7%, and 6.9%, respectively. The highest tensile strength was obtained when PPS was reinforced with 5 wt% Al 2 O 3 while highest bending strength and toughness were obtained with 20 wt% Al 2 O 3 . Reinforced composites encountered <5% and <14% mass loss when heated to 420 and 500 C, respectively. Lower filler concentrations (<5 wt%) had insignificant effect on the glass transition temperature (T g ) of the composite. Experimental results agreed well to Hashin-Shtrikman and Suquet predictions at lower filler concentrations since filler particles could be easily dispersed in the interstitial sites of PPS matrix without significant agglomeration. Besides, significant acoustic emission (AE) characteristic such as higher absolute energy rate was witnessed in Al 2 O 3 reinforced PPS composites. The insights derived from this study are expected to open a new avenue of producing composites with high stiffness, strength, and significant AE events by using zero-dimensional fillers.
