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 ...

The objective of this research was to investigate esponse of repeated low velocity impact tests on glass fibre/ epoxy-Al metal laminates (GEAML) and carbon fibre/ epoxy-Al metal laminates (CEAML) at the same location using drop-weight tester. CEAML, GEAML as well as monolithic Al panels of the same thickness were impacted repeatedly up to four impacts. The effect of repeated impacts on specimen...
