$\beta$-cyclodextrin($\beta$-CD)은 cycloheptaamylose라고도 하며 $D^{＜+>}$-glucopyranose 단위체가 7개 연결된 구조를 가지고 있다(Fig. 1). $\beta$-CD는 고리모양으로 되어있는데 외부는 친수성, 내부는 소수성을 갖는다[1]. 고리내 부가 소수성인 이유는 내부에 소수성기인 C-H그룹과 glucosidic oxygen만이 존재하기 때문이다[1].(중략)

Using conventional textile techniques such as weaving braiding knitting and stitching it is possible to produce a wide range two and three dimensional fiber preforms, however so far only a limited attention has been given to knitted fabrics in composite industry. This is mainly due to the opinion that knitted fabric reinforced composites posses low mechanical properties owing to their looped fiber architecture. But it is possible to obtain desired mechanical properties by selecting proper knitted fabric structure, In this paper mechanical characteristics of kevlar plain weft knitted fabrics reinforced plastics(KFRP) are evaluated for th development of intrusion beam of car side door. Tensile bending impact properties of KFRP are measured experimentally and crush demands of Americal Federal Motor Vehicle Safety Standard No.214(FMVSS 214) compared with the bending load and displacement of KFRP by quasi-static test method. The applicability and limitation of bending load and displacement of KFRP according to specimen size has been discussed.
