Summary: Environment friendly polymer composites made of plant based natural fibers offer lower carbon footprint, higher biodegradability, higher specific strength, higher thermal and acoustic characteristics. Synthetic glass fibers have high specific strength to weight ratio, great resistance during impact, and high durability. In this study, mechanical properties and thermal stability of hybrid laminates comprising of natural fibers and synthetic fibers were investigated. The findings show that fiber sequencing significantly affects the properties of the composite. The enhanced thermal stability and mechanical properties of the greener hybrid laminates make them suitable for various structural or lightweight industrial applications.

Summary: The use of glass fiber-reinforced polymer (GFRP) composites in load-carrying constructions has increased significantly in recent decades. Vinyl ester (VE) resins are being increasingly used in these structural composites, and their long-term environmental exposure consequences need better understanding. Testing the environmental durability of new VE-based GFRPs is time-consuming and costly, and accelerated hydrothermal aging is often used. This paper reviews the literature on hydrothermal aging of VE-based GFRP, focusing on moisture-induced aging, voids, and the fiber-matrix interface on composite mechanical performance.

Summary: A bio-based vinyl ester resin monomer was prepared and used to overcome the flammability and smoke release issues of vinyl ester resin. The impact of a diluent on the properties of the resin and its fiberglass-reinforced composites was investigated. The results showed that the bio-based resin and its composites had higher glass transition temperatures and improved mechanical properties compared to the conventional resin. Additionally, the bio-based resin exhibited superior flame retardancy and smoke suppression due to its better wettability on fiberglass.

Summary: This research focuses on the utilization of natural fibers, synthesized from Pennisetum orientale grass, as reinforcement in vinyl ester polymer for fabrication of composites. The mechanical properties of the composites were evaluated at different filler loading, and it was found that the properties initially increased with filler content until optimum fiber loading and then declined. The findings suggest that this composite can be used for weight reduction in automotive applications.

Summary: This study conducted a comparative analysis of basalt, E-glass, and hybrid fiber reinforced vinyl ester composites. The mechanical behaviors and surface morphology of impact fractured composites were analyzed, with different fiber orientations and volume fractions. The results showed that the glass and basalt fibers oriented at 0 degrees had higher load-bearing capability, while the fibers oriented at 45 degrees had higher plastic deformation. Hybrid composites with silane-treated glass fibers exhibited enhanced mechanical properties, including tensile strength, bending strength, toughness, and elongation at break, due to good bonding between fibers and polymer matrix. The tough and flexible interface between fiber and matrix allowed for increased resistance to shearing, resulting in improved strength compared to baseline composites.

Summary: This study explores the use of response surface methodology (RSM) to predict the compressive strength of bio-mortars and determine the optimal values for each parameter. Experimental and statistical analyses show that partially replacing cement with biochar produced from Washingtonia filifera waste pyrolysis improves the compressive strength and thermal conductivity of the bio-mortars. The findings demonstrate the feasibility of producing bio-mortars with a compressive strength of 63.81 MPa, a 1% replacement rate of biochar, and a coefficient of thermal conductivity of 0.52 W/m.K.

Summary: This study investigated the effects of different plasticizers (glycerol, fructose, sorbitol, and urea) on the morphological, mechanical, thermal, and physical characteristics of wheat starch films at various concentrations. The addition of plasticizers improved the flexibility and homogeneity of the films. Films plasticized with 35% sorbitol showed the highest elongation, while fructose showed the highest tensile strength at 35%. Glycerol films had the lowest water absorption at 35% fructose and showed coherent surfaces. Fructose exhibited the best performance with low water absorption, water content, and mass loss, and high mechanical performance at 35% concentration. SEM images showed that fructose and glycerol improved surface homogeneity, while sorbitol and urea had a less compact structure with large pores.

Summary: The study examines the use of black seed fiber as a reinforcing material for cornstarch-based biocomposites. Different concentrations of black seed fiber and a plasticizer mixture were used to fabricate the biocomposites. The results showed that increasing the black seed fiber concentration improved the mechanical properties and thermal stability of the films, but decreased biodegradability. The addition of black seed fiber has the potential to enhance the performance of biopolymers in response to community needs and environmental concerns.

Summary: This study investigates the shape memory properties of a shape memory epoxy polymer (SMEP) nanocomposite incorporated with a hybrid of multi-walled carbon nanotube (MWCNT) and montmorillonite nanoclay (MMT). The nanocomposites were characterized through cyclic thermomechanical tests and fold-deploy tests. The inclusion of the hybrid nanofiller resulted in a decrease in shape recovery, except for the SMEP nanocomposite. The recovery through thermal and electrically activated methods showed similar profiles, with electrically activated recovery reacting faster. The effect of nanofiller inclusion was more prominent in the thermal activation method. The hybrid filler SMEP nanocomposite with 3 wt.% MMT and 1.0 wt.% MWCNT exhibited better shape memory properties. These findings provide guidance for selecting nanofiller loadings based on performance for specific applications in industries such as aerospace, medical, and automotive.

Summary: In this study, PLA/NF biocomposites were prepared by melt extrusion method using locally grown natural fibers as fillers. PEG was added as a plasticizer to improve the processability of the PLA. Mechanical and thermal characterization were conducted to assess the processing effects of PLA/NF biocomposites. The results showed that the mechanical properties of PLA/NF biocomposites were improved compared to PLA. The DMA and TMA analysis revealed slight reduction in storage modulus and loss modulus, while the T-g values from DSC analysis remained unchanged. TMA analysis also showed a significant decrease in coefficient of thermal expansion values for PLA/NF biocomposites. Overall, PLA/NF biocomposites have the potential for novel biocomposite applications, especially in biomedical field, due to their good stiffness, tensile strength, and dimensional stability.

Summary: This study investigates the influence of hybrid reinforcements, namely CaCO3 particles and bentonite nano clay, on the wear and friction properties of high-density polyethylene (HDPE)-based composites. The results demonstrate a significant improvement in wear resistance, with the synthesized hybrid composite achieving a maximum improvement in wear rate of 93%. Morphological analysis reveals that the encapsulation and compatibilization effect of bentonite nano clay contribute to the improved wear performance. The prepared composite with enhanced tribological properties shows potential for use in low load-bearing wear applications such as turbo nanogenerators and piezo nanogenerators.
