Effect of Ammonium Polyphosphate/Silicate Content on the Postfire Mechanics of Epoxy Glass‐Fiber Composites Using Facile Chocolate Bar‐Inspired Structures

Fire and Materials, Volume 49, Issue 3, Page 329-346, April 2025.
ABSTRACT This study investigates the postfire mechanical properties of epoxy glass‐fiber reinforced composites (EP GFRCs) using increasing concentrations of ammonium polyphosphate (APP) and inorganic silicate (InSi) to modify the char and fire residue.

Polycarbonate Vitrimers and Dynamic Co‐Networks From Epoxide/Carbon Dioxide Copolymerization

Macromolecular Rapid Communications, EarlyView.
This work demonstrates how CO2‐derived poly(propylene carbonate) and poly(cyclohexene carbonate) backbones influence vitrimer thermo‐mechanical behavior. By tuning backbone composition, epoxide crosslinker chemistry and blend ratios, the crosslinked materials span a wide property window, from highly extensible to stiff, glassy networks, establishing an

Assignment-Consistent Dynamic Multi-UAV Task Allocation: Communication-Efficient Dynamic Multi-Unmanned Aerial Vehicle Task Allocation Under Stale and Asymmetric Information

Drones
Dynamic task allocation for unmanned aerial vehicles (UAVs) is often constrained by stale and asymmetric information. Variants of the Consensus-Based Bundle Algorithm (CBBA) can waste bandwidth by transmitting every state or bid update without ...

Effect of Nanosilica Aggregates/Agglomerates on Functional Properties of Poly(Butylene 2,5‐Furandicarboxylate)‐Based Nanocomposites

Polymer Composites, EarlyView.
Effect of nanosilica aggregates/agglomerates on oxygen and water vapor diffusivity of PBF/SiO2 nanocomposites. ABSTRACT The nanofillers inclusions in poly(butylene 2,5‐furandicarboxylate) (PBF)/SiO2 nanocomposites were found to consist of aggregates and agglomerates of nanosilica particles.

Second‐Life Thermoset Manufacturing via Mild Solvolysis of Epoxy‐Matrix Composites and Wet‐Laid Mat Production

Polymer Composites, EarlyView.
From end‐of‐life pultruded CFRP profiles (1) to second life composites (7) through mild solvolysis (2,3), wet‐laid nonwoven mat fabrication (4), resin impregnation (5), and compression molding (6). ABSTRACT The growing use of carbon fiber–reinforced thermosets has led to the accumulation of significant composite waste, posing environmental and economic

Robust β‐myrcene block copolymer elastomeric vitrimers

Polymer International, EarlyView.
Myrcene‐based vitrimeric elastomers were compared: statistical (poly(styrene‐stat‐myrcene‐stat‐AAEMA)] versus ‘hard–soft’ diblock (poly(styrene)‐block‐poly(myrcene‐co‐AAEMA)). The diblock's ability to anchor the glassy poly(styrene) blocks in a self‐assembled microstructure was effective – leading to four times higher tensile stress and ten times ...
