Energy absorption comparison of CFRP tube under humid conditions

摘要

The various parts used in the manufacture of automotives involve a range of different materials.nThere is now greater emphasis on vehicle safety and, in order to improve this, it is necessary tonincrease impact absorption capability. Recent research has focused on the suitability of carbonnfibre reinforced plastic (CFRP) because of its strength and light weight. It has many advantagesnbut there are also some disadvantages. The performance of CFRP is poor in a hygrothermalnenvironment. Giving CFRP circular members on constant temperature and humidity hinders anynimpact on the number of interfaces being checked. Specimens for each condition are comparednbased on change of energy absorption and water absorption rate. We have carried out a staticncollapse experiment to study the difference of energy absorption and impact modes.
