질소가 도핑된 탄소나노튜브강화 에폭시 복합재료의 압축거동에 대한 변형률 속도의 영향
Structures can be loaded statically or dynamically with a wide range of strain rate. With high strain rates, the relationships between stress and strain are not the same as in static loading. It has been observed that polymer composite properties are dependent upon the strain rate at which they are tested. The most commonly used method for determining the dynamic response of materials is the Split Hopkinson pressure bar, which can test materials at strain rates as high as 1200/s to 4200/s. The results showed strongly sensitive compressive behavior at high strain rates, i.e. structural properties of reinforcement and energy absorption capacity at high strain rates. Reinforcing nitrogen doped MWCNTs can effectively improve the compressive strength as well as the strain energy of the epoxy matrix due to their uniform dispersion in the epoxy matrix.
