In Situ Construction of Phosphorus‐Containing Crosslinked Urethane Network Combined With Ammonium Polyphosphate via Reactive Blending for Enhancing Flame Retardancy and Anti‐Dripping Performance of Polylactic Acid Composites

Safety Science and Technology, EarlyView.
By in situ reaction blending, DOPO‐HQ and THEIC were added to PLA with MDI to construct a phosphorus containing polyurethane network, which significantly improved the flame retardant and anti‐dripping properties of polylactic acid composites. ABSTRACT Polylactic acid (PLA) is highly flammable and prone to severe melt dripping during combustion, which ...

Engineering Phosphorus–Iron Coordination Complexes for Simultaneously Fire‐Retardant and Enhanced Epoxy Resins

Safety Science and Technology, EarlyView.
This flame‐retardant epoxy composite realizes synergistic fire suppression via gas‐phase and condensed‐phase dual mechanisms. In the gas phase, phosphorus‐containing radicals trap active H· and OH· radicals to interrupt flame combustion chain reactions. In the condensed phase, Fe species act as Lewis acid co‐catalysts to promote char formation, and the

From section to structure: Assessing the impact of localized corrosion on reinforced concrete beams

Structural Concrete, EarlyView.
Abstract The structural behavior of reinforced concrete (RC) elements affected by localized corrosion represents a major challenge for ensuring structural safety and for the proper design of strengthening interventions. The effects of localized corrosion on the flexural behavior of RC beams remain a topic of debate within the scientific community.

Influence of natural fibers on physical, mechanical, and fire‐resistant properties of microconcrete

Structural Concrete, EarlyView.
Abstract This study examined the influence of natural fibers on the physical, mechanical, and fire‐resistant properties of microconcrete, in comparison with conventional polypropylene fibers used in cement composites. The fibers were characterized by FTIR and TGA/DSC to assess their composition and thermal stability, and FTIR was also performed after ...

Cold‐curing effects on the strength development and sulfuric acid resistance of basalt fiber‐reinforced hybrid alkali‐activated slag mortars

Structural Concrete, EarlyView.
Abstract Cold weather conditions impose substantial constraints upon the performance and long‐term resilience of concrete materials. Alkali‐activated slag (AAS) presents itself as a promising substitute, exhibiting sustained hydraulic activity even when exposed to ambient conditions characterized by low temperatures.

Flexural and shear performance of HFRC beams

Materials Today: Proceedings, 2021
Abstract This paper describes the load bearing capacity prediction of two different types of fibres in Reinforced Concrete (RC) beams exposed to bending loads. A two-point test in a loading frame was conducted under static loading to examine the flexural and shear performance of Hybrid Fibre Reinforced Concrete (HFRC) beams in the preparation of ...

Bioinspirational understanding of flexural performance in hedgehog spines

Acta Biomaterialia, 2019
In this research, the flexural performance of hedgehog spines is investigated in four ways. First, X-ray micro-computed tomography (μCT) is employed to analyze the complex internal architecture of hedgehog spines. μCT images reveal distinct structural morphology, characterized by longitudinal stringers and transverse central plates, which enhance ...
