Enhanced interfacial and mechanical properties of carbon fabric/PA12 composites via grafting silanized nano hexagonal boron nitride onto the fibers

The purpose of this work was to create thermoplastic composites based on carbon fiber fabric reinforced enhanced mechanical and interfacial properties, based on PA12 (polyamide 12). In line with these objectives, it is aimed to develop carbon fiber reinforced thermoplastic composite materials with improved interfaces by sizing chemical modification and interfacial compatibility suspension development using hBN (hexagonal boron nitride) nanomaterial. The production of bare and silanized hBN sizing grafted CF (carbon fiber)-PA12 plates was followed by various mechanical, thermal, and SEM analyses. When the mechanical test results of CF-PA12 and hBN-APTES (3-Aminopropyltriethoxysilane) Sizing Coated Composite Specimens are compared; it is proved that hBN-APTES sizing improves the mechanical properties. Furthermore, sizing coated CF-PA12 composite specimens showed improvements in flexural strength of 20.67% and compressive strength of 19%, respectively. The significance of these results is to enhance the critical interfacial properties in the manufacturing of carbon fiber composite materials based on PA12, and to produce high-quality products that can be used in a variety of industries, including sports equipment, automotive, and aerospace, all of which have a constant demand worldwide.
