Abstract Polyurea (PUA) is widely valued in protective coatings and structural reinforcement because of its impressive mechanical strength and resistance to corrosion. Its high flammability, together with the poor dispersion that often comes with simply blending in flame retardants, continues to limit its use in demanding environments. To overcome these issues, this study introduces a different approach. We grafted 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide (DOPO) onto the surface of a metal–organic framework (MOF) and then partially amino-functionalized the DOPO layer, ultimately creating an amino-modified DOPO–MOF hybrid. The introduced amino groups can directly react with the isocyanate (–NCO) groups in the… More >

Abstract A comparative analysis was performed on poly(lactic acid) (PLA), poly(caprolactone) (PCL), basalt fiber (BF) composites produced using two distinct approaches: direct blending and masterbatching. The limitations of PLA-BF composites with regard to distribution and adhesion are well-documented, as are chemical treatment methods (addition of compatibilisers, surface treatments, silanization). This work aimed to study an industrially relevant potential solution of utilising a PCL-BF masterbatch, prepared as a 50/50 wt.% blend using planetary roller extrusion (PEX) to both improve the distribution and homogeneity of the fibers as well as provide a secondary adhesion site to facilitate improved… More >

Abstract Phenolic resins are widely used in thermal protection, yet achieving simultaneous improvement in thermal stability and mechanical strength remains challenging. In this work, a vinyl-modified silicone resin (VMTQ) was synthesized and incorporated into a boron phenolic resin (BPF) matrix. Three composite ceramic fillers, Al₂O₃–SiO₂–ZrO₂ (ASZ), Al₂O₃–SiO₂–TiO₂ (AST), and Al₂O₃–SiO₂–MgO (ASM), were further introduced to construct a multi-oxide synergistic reinforcement system. Thermogravimetric analysis shows that the maximum decomposition rate decreases by 0.2–0.3%·min⁻¹, while the ASM/V3/BPF-3 composite exhibits a 74.53% increase in char yield at 800°C and a 163.3°C increase in initial decomposition temperature, confirming its significantly enhanced thermal More >

Abstract The two distinct types of composite materials (5% to 10%) were developed using recycled polyvinyl alcohol fiber (RPA), silicon nitride fiber (SN), and reduced carbon nanoparticles (RCN). Enhanced microstructural properties and mechanical strength were attained through the application of the 3-glycidoxypropyltrimethoxysilane coupling method. The combination of the resin-like properties of RPA-SN fiber resulted in the formation of robust outer strength and a high bonding structure. RPA-RCN composite materials with a weight percentage of 10% exhibited a tensile strength of 42 MPa. In contrast, RPA-SN-RCN composite materials containing 5% to 10% demonstrated enhanced tensile, bending, and… More >

Abstract To comprehensively explore the impact of binder content on the mechanical properties of the Polymer bonded explosive (PBX) substitute material (Polymer-bonded Analogue Explosive (PAE)—it is renowned for its outstanding high-temperature resistance, exceptional mechanical properties, excellent chemical stability, and superior electrical insulation), a series of experiments are meticulously carried out. The dynamic and static mechanical properties, along with the microstructure of PAE, are precisely measured through the Split Hopkinson Pressure Bar (SHPB) test, static compression tests, and Scanning Electron Microscopy (SEM). The dynamic performance test outcomes clearly indicate that both the binder content (2%, 4%, 6%)… More >

Abstract The large thickness of the common composite precast base slab leads to difficulties in construction through reinforcement installation and pipeline laying. To solve this problem, this paper proposes a lightweight ribbed base slab, reducing the base slab thickness to 30 mm compared to the ordinary precast base slab, adding concrete ribs to improve the mechanical properties of the base slab, and analyzing its damage pattern, stiffness change, and deflection deformation through static loading experiments. Based on the experimental conditions, the effect of concrete rib height, rib width, and top chord reinforcement diameter on the short-term… More >

Abstract Engineered Cementitious Composites (ECC) represent an advanced class of fiber-reinforced cement-based materials developed over the past three decades, characterized by remarkable tensile strain-hardening and multiple-cracking behavior. By incorporating hybrid fibers, Hybrid Fiber engineered cementitious composites (HFECC) can be tailored to meet specific engineering demands in terms of strength, deformation, dynamic mechanical performance, and cost-effectiveness. This paper provides a comprehensive review of the critical fiber volume theory, experimental investigations into quasi-static and dynamic mechanical properties, and the structural performance of HFECC. Furthermore, current research gaps and future directions for the development and application of HFECC are More >

Abstract The high hydrophilicity of pineapple leaf fibres (PALF) limits their use in cement- and gypsum-based composites exposed to moisture. This study evaluates, for the first time, the combined effect of palm kernel oil and beeswax on the hygroscopic resistance and mechanical stability of PALF. The fibres were functionalised with three formulations (oil, wax, and a 1:2 oil/wax blend) applied at different mass ratios (CR = 0.5–2). Treatments increased the average bundle diameter by up to +46% (238 μm) and reduced density down to 1.06 g/cm³. Hygroscopically, water absorption decreased from 202.4% (raw fibres) to 76.3% (CR… More > Graphic Abstract

Abstract Melt blending of biodegradable polyesters such as poly (lactic acid) (PLA) and poly (butylene adipate co-terephthalate) (PBAT) with a compatibilizer and natural filler offers a chance to develop biodegradable bio-composites with improved performance. In this study, we examined how PLA/PBAT blends behave during ultimate biodegradation (mineralization), both with and without compatibilizer and algae as a reinforcement, under controlled composting conditions using carbon dioxide (CO₂) respirometry techniques. Throughout the biodegradation process, the disintegration behaviour, thermal, chemical, and morphological properties of test samples before and after biodegradation were analyzed using FTIR, TGA, DSC, and SEM techniques. The results… More > Graphic Abstract

Abstract This study explores the use of black soldier fly larvae protein as a bio-based adhesive to produce particleboards from sugarcane bagasse. A comprehensive evaluation was conducted, including rheological characterization of the adhesive and physical–mechanical testing of the panels according to European standards. The black soldier fly larvae-based adhesive exhibited gel-like viscoelastic behavior, rapid partial structural recovery after shear, and favorable application properties. Particleboards manufactured with this adhesive and sugarcane bagasse achieved promising mechanical performance, with modulus of rupture and modulus of elasticity values of 30.2 and 3500 MPa, respectively. Internal bond strength exceeded 0.4 MPa,… More > Graphic Abstract
