Summary: This study evaluated the mechanical and thermal properties of polypropylene composites reinforced with basalt fibers, using maleic anhydride as a compatibilizer. The mechanical properties of the composites were enhanced with increasing fiber content, but decreased beyond a certain threshold. The damping property of the composites was improved and showed good interfacial interaction between the fibers and matrix.

Summary: During the preparation of TiO2 continuous fibers, the use of high-pressure vapor pretreatment method can prevent fiber matrix strength reduction caused by the severe decomposition of organic ligands. The vapor pretreatment promotes precursor hydrolysis and reduces crystallization temperature, leading to the formation of compact fibers with high strength. However, the presence of water vapor can also cause the formation of defects in the fiber structure.

Summary: The study compared the properties of high-strength and ordinary concrete with different types of fibers (PPFs, HPP fibers, and SF) under standard and sulfate curing conditions. The addition of PPF and SF reduced the workability of the mixtures containing supplementary cementitious material. The mixture with 1% SF and 0.2% PPF showed the highest compressive strength, while the mixture with 0.5% HPP fibers, 1% SF, and 0.2% PPF showed the highest tensile strength. The flexural strength was highest in the mixture with 0.5% HPP fibers and 1% SF. Fiber-reinforced concretes had lower 30-minute water absorption compared to non-fiber samples, with the sample containing 0.5% PPF and 20% silica fume showing the lowest absorption of 0.53%.

Summary: In this study, graphene nanoplatelets and titanium dioxide nanofillers were added to epoxy resin and their effects on the tensile properties and shear strength behavior of the nanocomposites were investigated. The research showed that epoxy/graphene nanocomposites had the highest tensile strength and joint failure load, and the artificial neural network model provided the most accurate predictions for these nanocomposites.

Summary: This research focuses on lightweight products for the transportation industry, introducing recycled carbon fibers and elastomers to polypropylene matrix to improve strength and toughness. The addition of 20 wt% recycled carbon fibers led to significant enhancements in heat distortion temperature, tensile strength, and stiffness. Fractography analysis revealed that the presence of fibers predominantly governs the impact resistance characteristics of the composites.

Summary: This study explores the use of wood-fiber-based fabrics containing Lyocell yarn and Spinnova-Lyocell yarn to form unidirectional all-cellulose composites (ACC) through dilution in a NaOH-urea solution. The tensile properties and thermal stability of the ACC were compared to thermoplastic biocomposites prepared with biobased polypropylene (PP). The ACC showed higher tensile strength in the warp direction and doubled elongation at break compared to other samples, while also exhibiting higher thermal stability. Furthermore, the ACC demonstrated significantly higher water absorption compared to the PP biocomposites. These findings highlight the unique properties of ACC and suggest potential commercial applications.

Summary: The combination of long glass fiber-reinforced composite and recycled composites significantly altered the length distribution of glass fibers, resulting in a significant recovery of mechanical properties of the recycled composites. The mixing ratio, number of recycles, and distribution of glass fiber length all have an impact on the mechanical properties of the composites.

Summary: This study investigates the development of antistatic PP composites using Li-TFSI. It reveals that the polar effect of Li-TFSI promotes the formation of conductive tracks, while heterogeneous nucleation enhances the nucleation and crystal growth of PPR chains. The addition of Li-TFSI reduces the interface strength but increases the modulus.

Summary: This study analyzed the thermal degradation and mechanical properties of iron (Fe)-containing MgAl layered double hydroxide (LDH)-based polypropylene (PP) nanocomposites. Experiments showed that increasing the iron (Fe) content led to a decrease in melt viscosity, an increase in burning rate, and a decrease in mechanical properties in LDH/PP nanocomposites.

Summary: The study focused on developing a new low carbon composite material using illite clay and titanium dioxide as stabilizing and whitening agents. It was found that the addition of low loading of titanium dioxide significantly impacted the whiteness index, stability of tensile strength, and Young's modulus of the composites. The thermal stability increased by approximately 7% with the inclusion of illite-titania composite at 18:2 weight ratio.
