Summary: This study investigates the effects of adding betel nut powdered particles to epoxy composites reinforced with corn husk fibre. The mechanical, wear, and hydrophobic behavior of the surface-treated betel nut particles and corn husk fibre in epoxy resin are examined. The findings show that the addition of 40 vol. % corn husk fibre and 3.0 vol. % betel nut particles in epoxy enhances the tensile strength, flexural strength, hardness, and other properties of the composite. However, an increase in betel nut particles leads to a deterioration in mechanical and wear characteristics. The composite with the highest water absorption percentage also exhibits enhanced bonding between the fibre and matrix. Such materials can be used in various engineering applications.

Summary: This study aimed to synthesize cardanol-based mono, bi, and tetrafunctional benzoxazines through the Mannich condensation of various aryl and cycloaliphatic amines with cardanol. The benzoxazines were characterized for their molecular structure, curing behavior, thermal stability, and hydrophobic nature. It was found that tetra-functional benzoxazines have a lower curing temperature and that cycloaliphatic amine-based benzoxazines have a lower curing temperature compared to aryl amine-based benzoxazines. The thermal stability and water contact angle of the benzoxazines were also investigated, showing variations among different systems. The results suggest that cardanol-based tetrafunctional benzoxazines can have applications in microelectronics and automotive industries.

Summary: A new hybrid fabrication technique was introduced to manufacture composite laminates consisting of glass fiber, carbon fiber, and ABS as the matrix. The fabricated composite laminates were tested for wear at different velocities and loads. The results showed that GF/ABS samples had the lowest wear loss at 5 N and a velocity of 4 m/s, while GF/CF/ABS hybrid samples had the lowest coefficient of friction at 4 m/s. Scanning electron microscopy analysis revealed the adhesion behavior between fibers and matrix. These composite materials are widely used in various applications due to their high strength-to-weight ratio and resistance to wear.

Summary: In this study, a new type of bio-based tyrosine-dipeptide (TB) was synthesized and converted into a modified benzoxazine (TB-Bz) using different amino compounds and formaldehyde. The structure of these benzoxazines (TB-a, TB-dd, and TB-ff) was analyzed and their curing behavior and thermal stability were examined. The results showed that the poly(TB-ff) coated specimen exhibited the highest corrosion protection efficiency of about 98.3%. Therefore, the bio-based tyrosine dipeptide benzoxazines developed in this study can be considered as a better coating material for mild steel surfaces under adverse environmental conditions.

Summary: Four different series of sesamol-based benzoxazines were synthesized using various amines, and were used for hydrophobic coating, low dielectric and high dielectric applications. The chemical structure, curing behavior, thermal stability, water contact angle (WCA), and dielectric characteristics were evaluated. Poly(S-ffa) and poly(S-dde) exhibited higher char yield compared to other polybenzoxazines studied. Poly(S-tfma) showed a higher WCA (152 degrees) and superhydrophobic behavior. Bamboo ash-based bio silica reinforced poly(S-ffa) composites had a dielectric constant and dielectric loss of 2.36 and 0.0033, respectively. 15 wt% of cardanol functionalized graphitic carbon nitride (GCN-c) reinforced poly(S-dde) composites showed the highest values of dielectric constant (7.82) and dielectric loss (0.0029).

Summary: This study analyzes the erosion mechanisms of NaCl solution on asphalt concrete and finds that NaCl solution softens asphalt and promotes the intrusion of crystalline salt into it. Salt crystallization alters the surface roughness of aggregates, resulting in a decrease in skid resistance but an improvement in compressive strength. Additionally, the concentration of NaCl solution initially has no significant impact on the mechanical performance of asphalt concrete, but its domination gradually increases with the intensification of cyclic effects.

Summary: This paper investigates the effect of freezing and thawing cycles on the tensile behavior of cracked ultra-high performance concrete (UHPC). The results show that long-term freezing and thawing action deteriorates the cracking strength, tensile strength, tensile strain, and strain energy of cracked UHPC. On the other hand, the action of water generally favors the development of tensile properties of UHPC. The crack distribution tends to be unsaturated under freezing and thawing environment, and the re-hydration reaction is hindered. The pore structure near the crack varies under different environments.

This study focuses on solidifying tailing sand using microbial induced calcite precipitation (MICP) to improve strength and fix heavy metals. The curing time of MICP bio-cemented tailings is found to significantly impact the strength of tailings, while its effect on heavy metal fixation is minimal. The optimized MICP curing time is 10 days, resulting in improved strength and cementation of tailings particles.
