Summary: Epoxy-bamboo long natural fibres composites were prepared by hand lay-up method to study the influence of fibre's treatment on their characteristics. SEM showed increased surface roughness due to the removal of amorphous compounds from the treated fibre as confirmed by the disappearance of certain peaks in FTIR spectroscopy. Resultantly, similar to 52% increase in crystallinity was observed by XRD analysis. TGA results also showed the effectiveness of the treatment as mass loss for treated fibres was similar to 15% lesser than the untreated fibres. Moreover, thermogravimetric analysis of composites showed highest mass loss in untreated fibres composites and lowest in neat epoxy. The DSC-DTA curves indicated an early start of initiation temperature in treated fibre composite. Tension tests showed similar to 12% and similar to 16% increase in tensile strength and modulus respectively for treated fibres composite due to increased interfacial strength caused by fibre treatment. Treatment also resulted in decreased impact energy and water absorption level.

Summary: The effect of nanosilica modification on the mechanical properties of unsaturated polyester composites reinforced with pure jute and hybrid jute-high tenacity polyester (HTPET) fabrics was investigated. The study found that nanosilica modification improved adhesion between the polyester fibers and the matrix, causing surface roughening. However, the adhesion of jute fibers reduced due to the filling and smoothing of their inherent roughness. The hybrid sample with polyester fibers in its outer layers showed the largest increase in flexural and impact properties.

Summary: This study explored the performance of bamboo particle boards (BPBs) made from unsaturated polyester resin (UPR) with toluene diisocyanate (TDI) as the coupling agent. Results showed that covalent bonds were formed among TDI, bamboo particles, and UPR, significantly enhancing the mechanical strength and improving thermal stability. The treated BPBs exhibited significant improvements in internal bonding strength, modulus of elasticity, and modulus of rupture, and had lower thickness swelling rate. Therefore, using UPR as the adhesive and TDI as the coupling agent in BPBs offers better usability, higher efficiency, and excellent mechanical strength.

Summary: A new methodology was developed to disperse nanofibrillated cellulose (CNF) in polylactic acid (PLA) composites for 3D printing. The nanofibres were modified by grafting PLA onto their surface through in-situ polymerisation of L-lactide. This modification changed subsequent fibre/PLA interaction and enabled the production of reinforced microparticles by a Pickering emulsion approach.

Summary: This study investigates the effect of poly(catechol/amine) treatment of bamboo flour (BF) on the performance of BF/high-density polyethylene (HDPE) composites. The results show that different monomers used for treatment can increase the diameter of BF, as well as the fractal dimension and specific area of the BF surface, promoting its interaction with other substances. The treated BF exhibits improved interfacial bonding with HDPE, leading to enhanced physical-mechanical properties of the composites.

Summary: Hexagonal boron nitride (h-BN)-based composites have versatile and significantly improved properties, making them highly valuable in various industries. This review article critically examines the crystal structure and enhanced properties of h-BN, as well as the fabrication methods, mechanical properties, and applications of h-BN-based ceramics and composites with different materials. The results show that hot pressing enhances mechanical properties through the incorporation of BN, while pressureless sintering leads to poor mechanical properties due to porosity and poor bonding between h-BN grains. These findings provide valuable insights for the development and application of h-BN-based materials.

Summary: This paper presents a study on 3D novel hybrid auxetic structures made with carbon fiber reinforced polymer (CFRP) laminate composite. The mechanical characteristics of the designed structures, such as Young's modulus, shear modulus, and Poisson's ratio, are evaluated through theoretical analysis and finite element simulation. The results show that the structures have negative Poisson's ratio values in all ranges of design geometry parameters. The optimized geometry parameters are achieved through a multi-objective optimization method based on maximizing stiffness and minimizing relative density responses. Additionally, the mechanical behaviors of the assembled 3D structures are studied through quasi-static compressive tests to measure the negative Poisson's ratio values using strain gauges and a video extensometer. The proposed structures exhibit superior stiffness and high elongation percentage, making them a strong candidate for the next generation of load-bearing auxetic structures.
