Abstract
Carbon Fiber Reinforced Plastic(CFRP) materials of the aircraft can absorb water, which could decrease the adhesion strength of these materials and cause their volumes to change with variation in internal stress.Therefore, it is necessary to study the changes of the characteristics in the extreme environments in order to identify the environmental impact of CFRP.In this study, we evaluated the properties of CFRP by the tensile test and bending test as specified in ASTM standard.After the fabrication of the CFRP specimen directly by using a water bath to set the environmental temperature and humidity, specimens were soaked in distilled water at 75℃, for one week, two weeks and three weeks respectively.Mechanical Characteristics of CFRP were observed through Tensile test and Bending test.
