Coupling Agent - an overview | ScienceDirect Topics
Coupling agents are used to enhance the interfacial adhesion, which directly affects the strength properties of composite panels. The coupling agents have high compatibility with the fiber-matrix and help reduce moisture absorption, reducing the leaching effect and improving the fiber wettability (Saha et al., 2016). Coupling agents such as ...
Covalently grafting silane coupling agents onto …
2024年11月7日 · Two-dimensional (2D) MXene (MX) and silane coupling agents are increasingly used to modify carbon materials for the fabrication of composite functional materials, which exhibit enhanced electrical, optical, and mechanical properties due …
coupling agent is a chemical which improves the adhesion between two phases in a composite material. The term 'composite' is used here to denote a material which has two or more distinct constituents, not chemically bound to each other. The two examples of composite materials that are especially relevant here are:

The maleic acid functionality can react with functional groups on the polymer matrix and reinforcing fillers, promoting better interfacial bonding.
Fiber sizings: Coupling agent companions - CompositesWorld
2013年8月1日 · Although the primary function of sizing is to protect the fiber from abrasion damage by acting as a dry lubricant during processing functions such as weaving, sizing expert Andy Brink, business development manager at Michelman SARL (Cincinnati, Ohio), says sizings on reinforcements used in composites also contribute to adhesion at the fiber/resi...
Effect of Different Coupling Agents on Interfacial Properties of …
2021年2月21日 · Metal composite interface properties significantly affect the integrity, bonding properties, and interface structure of Fibre Metal Laminates (FMLs). Interfacial bonding strength’s effect on Carbon Fibre-Reinforced Aluminium Laminate (CARALL) mechanical behaviours was investigated via three-point bending and low-velocity impact tests.
