Summary: This study investigates the surface morphology, flammability, and tensile properties of sugar palm fiber (SPF) hybrid with polyester (PET) yarn-reinforced epoxy composite by adding magnesium hydroxide as a flame retardant. The results show that incorporating 35% SPF with magnesium hydroxide as a flame retardant reduces burning rate and increases tensile strength. However, at 50% SPF content, the lack of interfacial bonding between fibers and matrix decreases the tensile properties of the composite.

Summary: This study investigates the effects of flame retardants on water sensitivity and the impact of water absorption on fire behavior and mechanical performance of biocomposites. The results show that DOPO flame retardant increases the equilibrium water content, while AlPi does not significantly affect water sensitivity. Mechanical properties are influenced by moisture content, and only the highest water contents modify the fire behavior.

Summary: This study aimed to investigate the impact of surface modification of basalt fibers on the mechanical properties of basalt fiber-based epoxy composites, finding that the best performance was achieved with a combination of acetone pretreatment and KH550 formal surface treatment. The incorporation of modified basalt fibers slightly reduced the LOI value, but maintained good performance in vertical burning test and increased the peak of the heat release rate.

Summary: In this study, the phosphorous-based flame retardant additives poly(m-phenylene methylphosphonate) (PMP) and resorcinol bis(diphenyl phosphate) (RDP) were covalently incorporated into the structure of PMP, with initiating phenols and free phenols generated through transesterification reaction. Compared to PMP, RDP elongated the processing window but decreased the thermo-mechanical properties. Both additives enhanced resistance to small flames with a phosphorous loading of 0.3 wt%, resulting in a V-0 rating and up to 2% improvement in the OI value for RDP and 4% for PMP. Both FRs reduced the heat release rate but increased smoke production and smoke toxicity in the case of RDP.

Summary: The study examined the effect of wood dust fibre treatment on the properties of wood dust reinforced recycled polypropylene composite (r-WoPPC) filament. The wood dust fibre was treated with alkali, silane, and NaOH-silane. The silane treated wood fibre showed the highest wire pull strength due to enhanced interfacial bonding with recycled PP. The treated filament also exhibited minimal void, gap, and good fibre adhesion, resulting in reduced water absorption and improved mechanical properties.

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 paper investigates the thermal, tensile strength, and flexural strength properties of a polyester composite filled with hybrid Eichhornia crassipes (EGs) /aluminum oxide (Al2O3) particles. The results show that the tensile and bending strengths increase when the EGs content in the composite is in the range of 10-15%. The scanning electron microscope fracture morphology reveals a strong and tight interfacial connection between the EGs, Al2O3, and polyester layers. According to the findings, this hybrid composite can be used in automotive applications.
