CFRP 복합재료의 적층 구성에 따른 정적시험 평가 = Evaluation on the Static Test of CFRP Composites with Respect to Stacking Sequence

다국어 초록 (Multilingual Abstract)

CFRP composite materials are used increasingly in various fields such as space and aviation industry, architectural structures, shipbuilding materials, sporting goods, and interior materials of automobiles due to the excellency of mechanical characteristics as well as light weight, heat resistance, and control characteristics. Stacking plates of CFRP composite materials, which are used increasingly because of these unique characteristics, have the properties of uneven quality and anisotropic nature unlike general metallurgical materials as they are stacking plates of composite materials in the combination of different types of materials.
Hence, in this thesis, specimens of stacking composition of stacking plates of CFRP composite materials were manufactured by changing orientation angles in three kinds of quasi-isotropic such as (0˚/45˚/90˚/-45˚)6S, (0₃˚/45₃˚/90₃˚/-45₃˚)2S, and (0₆˚/45₆˚/90₆˚/-45₆˚)S and also in three kinds of orthotropic such as (0˚/90˚/0˚/90˚)6S, (0₃˚/90₃˚/0₃˚/90₃˚)2S, and (0₆˚/90₆˚/0₆˚/90₆˚)S.
In this study, it was possible to obtain the following results by carrying out 3-point bending testing and transverse bending testing order to find out mechanical characteristics according to orientation angles by stacking in 6 different types with the changes of stacking composition methods of CFRP composite materials. As interface number increases, the maximum load was increased and specimens stacked in quasi-isotropic haulage operations in its maximum load rather than orthotropic. Therefore, it is judged that it is correct to stack in quasi-isotropic when composing stacking of CFRP composite materials.
