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.

The impact of using prestressed CFRP bars on the development of flexural strength

Open Engineering
The load-carrying capacity and ductility of conventional steel reinforcement may be greatly increased by using ordinary and prestressed carbon fiber-reinforced polymer (CFRP) bars, resulting in reinforced concrete structures with greater sturdiness. This

Experimental study on end face grinding stability of thin-walled CFRP circular cell

Jin'gangshi yu moliao moju gongcheng
ObjectivesCFRP circular cell honeycomb consists of thin-walled circular cells and are applied in the aerospace. It is difficult to machine the CFRP honeycomb due to its characteristics of thin walls, weak rigidity and non-continuous periodicity.

Emissivity measurements of reflective surfaces at near-millimeter wavelengths [PDF]

, 1995
We have developed an instrument for directly measuring the emissivity of reflective surfaces at near-millimeter wavelengths. The thermal emission of a test sample is compared with that of a reference surface, allowing the emissivity of the sample to be ...

Catalyst‐Free Mass Polymerization and Characterization of Bio‐Polyhydroxhyurethanes Based on Resorcinol Bis(Cyclocarbonate)

Macromolecular Materials and Engineering, EarlyView.
Non‐isocyanate polyhydroxyurethanes (PHUs) were synthesized from resorcinol bis(cyclocarbonate) and eco‐friendly diamines under mild, catalyst‐free conditions. The resulting polymers were extensively characterized for their structural, thermal, and mechanical properties, as well as processability and adhesion performance.

Carbon Fiber-reinforced Plastic Surface Modification by Al Electroplating in AlCl3–EmImCl Ionic Liquids

Electrochemistry
In this study, Al electroplating and anodization were performed to improve the wear resistance of the carbon fiber-reinforced plastic (CFRP) surface. The adhesion strength between the Al electroplating film and CFRP was improved by etching the resin part
