Summary: In this study, sisal-fiber-reinforced polypropylene (PP/SF) flame-retardant composites were prepared using the two-step melt blending method. An intumescent flame retardant (IFR) composed of silane-coated ammonium polyphosphate (Si-APP) and pentaerythritol (PER) was used. The PP/SF composite prepared by PP/SF secondary blending with IFR showed excellent flame-retardant performance, with a limited oxygen index of about 28.3% and passing the UL-94 V-0 rating (3.2 mm) in the vertical combustion test. The mechanical properties of the composites prepared using three different mixing processes were similar.

Summary: This study investigates the impact of sisal fiber content up to 30% on the mechanical and thermal properties of PLA matrix composites. Results show that the best properties were achieved with 20% fiber content, and beyond this, a slight decrease was observed. Sisal fiber enhanced crystallinity at 10% content and acted as a reinforcing and nucleating agent for PLA, making the biocomposites suitable for various applications in aerospace, automotive, and construction.

Summary: This research aims to develop a sound-absorbing material made of polypropylene and sisal fibers, and explores the foam processability with near-critical fiber length and supercritical CO2-assisted batch foaming technology. The optimized foam processing conditions result in foams with the lowest density, maximum volume expansion ratio, and overall microcellular structure. Increasing the fiber concentration significantly improves the compressive properties, and foaming enhances the sound absorption properties. This material is highly applicable for soundproofing purposes.

Summary: In this study, sisal fiber reinforced nanosilica and cardanol oil toughened epoxy composites were prepared and characterized. The addition of cardanol oil and nanosilica was found to enhance the load bearing, thermal stability, and antimicrobial properties of sisal-reinforced epoxy composites. The composites showed improved mechanical properties, such as increased tensile strength and modulus, as well as improved impact resistance and hardness values. The antimicrobial properties also improved with the increase in nanosilica and cardanol oil content. These environmentally friendly biocomposites could find applications in various industries including drug and food storage, automotive, structural, and sports goods manufacturing.

Summary: The addition of crab shell particles can significantly improve the flexural and tensile strength of hybrid composites, but adding more than 4% can lead to a decrease in performance. Morphological behavior of the fractured surface confirmed the existence of better bonding between the fiber and matrix, and FTIR identified the functional groups of sisal fiber and crab shell particles.

Summary: The study focuses on summarizing the synergistic effect of basalt fiber on mechanical, thermal, and morphological behavior of PP/bamboo composite. Different levels of basalt fibers (5, 10, 15, and 20 wt%) were used to replace 40 wt% of bamboo fiber, while maintaining a constant fiber content of 40 wt%. PP/bamboo composite and PP/bamboo/basalt hybrid composites were fabricated through melt compounding and injection molding. The addition of silanized basalt fiber in the composite improved tensile and flexural properties, while reducing impact strength. The inclusion of both bamboo and basalt fiber increased the crystallinity of neat PP and enhanced the viscoelastic properties.

Summary: The aim of this research is to measure the dielectric properties and electromagnetic interference (EMI) shielding effectiveness (SE) of silicone rubber reinforced with graphene nanoplates. Different amounts of graphene are mixed together using a two-roll mill, followed by compression moulding and post-curing. The dielectric and EMI SE parameters are measured using the waveguide transmission line method and a vector network analyzer. Increasing the amount of graphene leads to higher AC conductivity and the highest EMI SE is achieved at 7wt% graphene content.

Summary: The study investigates the effect of incorporating carbon nanotube (CNT) fillers on the mechanical and tribological properties of silicon rubber (SiR). The nanocomposite is prepared by mixing the materials in a three-roll mill, compressing the mixture, and curing it. The tensile strength increases by 3% for every 1% increase in CNT weight percentage up to 7%, after which it stabilizes. The coefficient of friction (COF) is lowest at 3% CNT load and decreases with increasing load. Heat and nanoparticle aggregation contribute to the increase in COF as CNT fraction increases. Changes in sliding velocity affect both COF and specific wear rate.
