Impact penetration test and residual tensile strength of CFRP

open access: yesNihon Kikai Gakkai ronbunshu, 2022
The high-pressure hydrogen tank for fuel cell vehicles is made by the prepreg winding method using carbon fiber reinforced plastics (CFRP). Unexpected destruction may occur in the high-pressure hydrogen tank due to internal pressure if an impact load is ...

Residual Repeated Impact Strength of Concrete Exposed to Elevated Temperatures

open access: yesCrystals, 2021
Portland cement concrete is known to have good fire resistance; however, its strength would be degraded after exposure to the temperatures of fire. Repeated low-velocity impacts are a type of probable accidental load in many types of structures. Although

Effect of Elevated Temperatures on Mechanical Properties of Spliced and Non-Spliced Steel Reinforcements: Experimental Study

open access: yesBuildings, 2023
Steel reinforcement is an essential part of reinforced concrete, providing structural strength. In case of fire, the steel reinforcement severely loses its mechanical properties, leading to structural collapse in some elevated temperatures.
