Fire properties of carbon fiber reinforced polymer improved by coating nonwoven flame retardant mat for aerospace application

Abstract

In this study, two types of carbon fiber reinforced polymer (CFRP) flame retardant composites, CFRP@MatEG‐GF and CFRP@MatEG‐GF‐MW (EG, GF, and MW are the acronyms of expandable graphite, glass fiber and mineral wool, respectively), were prepared via compression molding, with expandable graphite‐based mat incorporated at the surface of the CFRP. The results showed that compared with the control CFRP, both CFRP@MatEG‐GF and CFRP@MatEG‐GF‐MW passed vertical burner test and 45° burner test according to FAR25.853. Moreover, the limiting oxygen index (LOI) values of both CFRP@MatEG‐GF and CFRP@MatEG‐GF‐MW were increased, and the peak of heat release rate (PHRR) and total heat release (THR) were reduced. Besides, CFRP@MatEG‐GF‐MW had higher flame retardancy than CFRP@MatEG‐GF. This was attributed to the formation of a more stable and dense carbon layer structure. The mechanical test results showed that the tensile strength of CFRP@MatEG‐GF‐MW was higher than that of CFRP@MatEG‐GF. © 2019 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2019, 136, 47801.

Electrochemical grafting of poly(glycidyl methacrylate) on a carbon-fibre surface

“…Carbon bre (CF) is one of the most valuable reinforcements for advanced composites due to its high specic strength, high specic modulus, low density and excellent thermophysical properties. [1][2][3] It has been widely used in the aerospace, automotive, sports and construction elds. [4][5][6] It is well documented that mechanical properties of CF composites are closely associated with the interface between the CF and resin matrix.…”

Electrical Current Map and Bulk Conductivity of Carbon Fiber-Reinforced Nanocomposites

“…To fully apply composite materials in wide extent in aircraft vehicles, several drawbacks still need to be overcome, such as a suitable electrical conductivity to better cover several functions (e.g., lightning strike and electromagnetic compatibility issues) and continuous enhancement of fire safety in aviation materials. Many relevant achievements have been described in the literature in this direction [1,2,3,4,5,6,7,8,9,10]. Many functions can be conferred to aeronautical composites by proper use of nanotechnology, for example by embedding nanostructured materials with exceptional properties, like carbon nanotubes (CNTs), in aeronautical grade epoxy resins before or during the manufacturing processes [11,12,13,14,15,16].…”

Investigation of Fire Protection Performance and Mechanical Properties of Thin-Ply Bio-Epoxy Composites

“…The results indicated that the fire-retardant mat was effective as a barrier layer and the general mechanism of protection was that the expanded graphite formed a protective char. It was also observed that the EG tended to peel away from the mat, which may pose a health issue [ 19 ].…”
