The predominant use of FBG sensors to characterize the residual stress state in composite materials date does not permit absolute strain measurements. reason for this is loss connection between sensor and laminate during phase transitions resin. Thus, points significant changes measurement signal (e.g. bonding temperature) need be used evaluation. For fiber metal laminates (FML) however, gages ...

Abstract Glass fiber-reinforced polymer materials have been effectively used in civil aviation aircraft, but due to low electrical conductivity, a large area of ablation damage will occur after lightning strikes, which greatly threatens the safety aircrafts. Based on this, coupled electrical-thermal finite element analysis model for glass fiber reinforced is established, and results are compare...
