Microwave Curing Characteristics of CFRP Composite Depending on Thickness Variation Using FBG Temperature Sensors

Abstract: Microwave curing technology, which has seen increased commercialization recently due to its ability to cut the curing time and ensure high quality, requires an understanding of the curing characteristics of composite materials of varying thickness. Therefore, this study aimed to perform cure monitoring to evaluate the effects of variations in thickness on the quality of microwave curing. For this study, a fiber Bragg grating sensor was used to measure temperature changes in specimens during the curing cycle fo… Show more

“…[1][2][3][4] At present, the curing sources suitable for CFRP in-situ curing technology includes thermal curing, ultraviolet light (UV) curing, X and γ radiation curing, microwave curing, electron beam curing and so on. [5][6][7][8][9][10][11][12][13] Curing black carbon fiber composite materials using is challenging for UV radiation due to its poor penetration along the thickness of CFRP. 14 The dose rate of X and γ radiation is lower than that of E-Beam, resulting in a curing time for X-ray that is approximately 60 times longer than E-Beam.…”

“…15 Microwave curing requires further research to ensure uniformity during solidification and control over microwave reflection in carbon fiber composites. 12 In contrast, the E-Beam curing technology offers several advantages such as fast solidification rate, low solidification temperature, and strong operability, and has rapidly become a research hotspot in scientific research and engineering circles since its first application to the radiation curing of resin matrix composite materials by the French AERO-SPATIAL company in 1996, [16][17][18][19][20][21] and is considered to be the most promising application in OOA curing for CFRP.…”

“…That is, the process from CFRP design to manufacturing must be monitored. Although studies have explored the monitoring process [13,14], most have focused on resin curing monitoring [15][16][17][18] or on the residual stress during resin curing [19,20], However, fiber angle monitoring is the most critical area that needs focus, as the reinforcing material undergoes mechanical loading [21].…”
