“…특히, 천연섬유의 하나인 양마(Kenaf, 이하 KN)를 섬유보강재로 사용할 수 있는 가능 성을 제시한 연구도 보고되었으며, 또한 국내에서도 세계 3대 섬유작물인 KN(장대)의 국산화 성공과 새만금 및 경기 화옹간척지 등에서 재배하기 시작하여 대량생산을 통해 본격 적으로 산업소재 시장에 진출할 것으로 예상되고 있다 [8,9].…”

“…KN의 줄기에서 가공된 KN섬유는 표면이 거칠고, 인장 력 및 부식저항성이 우수하며, 셀룰로오스 함량이 약 60∼ 70%, 리그닌 함량이 10∼20%로 높고 생육이 빨라서 생산 성 및 경제성이 우수하기 때문에, 이를 섬유보강재로 사용할 경우에 인장강도와 부착력의 증진 및 소성수축 균열의 감소 는 물론 친환경적인 소재의 활용성 측면에도 큰 효과가 있을 것으로 사료된다 [8].…”

This study is to examine experimentally on the engineering properties of fiber reinforced concrete using kenaf(KN) fiber and another organic fibers for comparing test, and propose the usable method of KN fiber as an natural fiber in the concrete industry. It is to select 4 contents(0, 0.3, 0.6 and 0.9 ㎏/㎥) of KN fiber and 4 organic fibers (Jute, Cellulose, Polypropylene and Nylon). For this study, it is to perform various tests including slump, air content, plastic and drying shrinkage, flexural and tensile strength, carbonation depth for the fiber reinforced concrete according to contents of KN fiber and 4 organic fibers. The results of this study are as follows : In case of KN fiber contents 0.6 ㎏/㎥, it shows the effective results from increasing concrete strength including flexural and tensile, from decreasing plastic and drying shrinkage, carbonation depth. Also KN fiber is confirmed having excellent performances by comparing with test results of another organic fibers as same contents 0.6 ㎏/㎥. Therefore, considering concrete test results, cost and environment, KN fiber is proposed as the optimum contents in the range of 0.6 ㎏/㎥ and an effective fiber materials, and needs to keep up these study on the site application.

The purpose of this study is to establish experimentally the mechanical properties of fiber reinforced concrete using kenaf dosages and propose the usable method of kenaf fiber in the concrete industry as natural fiber materials. Kenaf fiber help make the concrete strength including tensile and flexural stronger, more resistant to plastic and drying shrinkage, less amount of carbon dioxide because of having a rough surface and excellent tensile strength of fiber and improving the concrete's corrosion resistance. It is to select the kenaf dosages of 4 cases (0, 0.3, 0.6 and 0.9kg/m 3 and perform various tests including slump, air content, plastic and drying shrinkage, flexural and tensile strength for fiber reinforced concrete.The results of this study are as follows : In case of increasing kenaf fiber dosages, show the slump decrease and air content increase, also take effect results for increasing concrete strength including flexural and tensile, decreasing plastic and drying shrinkage. therefore, considered test results and cost, the optimum dosages of kenaf fiber is proposed about 0.6kg/m 3 and need to study on the site application considering concrete quality and another compared tests.

“…The performance of the fibre reinforced composites mainly depends on the fibre matrix and the ability to transfer the load from the matrix to the fibre [14][15][16][17]. Also, natural fibre composite materials are applied with a wide energy absorption structure [18][19][20].…”

This current study is to investigate the behaviour of the kenaf/wool natural fibre. Reinforced composite elliptical cones with different content of fibre for each of the two types separately in absorbing energy and the load capacity, the lack studies about the composite elliptical tube, our focus was on this shape of shells of effect content of fibre for each of the two types separately. Various fibre contents were considered, including 30 wt%, 35 wt% and 40 wt%. The composite elliptical tubes were subjected to an axial quasi-static crushing test to achieve the study objectives; the methodology has been divided into three main sections concerning the problem statement, the first section is the mandrels preparation; the second section is specimen's fabrication process and finally is the crushing test. This study concerns the usage of the composite elliptical tube as a collapsible energy absorbing device within an automobile structure, which is supported at the distal end (i.e. the point of attachment) by a stronger structure and is designed to behave in a manner more similar to the quasi-static axial regular progressive mode. Therefore, quasi-static axial compression tests were performed on the tubes using INSTRON universal servohydraulic testing machine. The materials used in this study are polymer resin and kenaf/wool fibres. Environmentally friendly kenaf and wool fibre were used in this study due to several advantages such as environmentally benign, lightweight, low cost, no health risk, and availability. Results showed that including 30 wt% has a higher value of load-caring capacity and energy-absorption capability than including 35wt% and including 40 wt%. The results also show that the wool fibre has a higher value of load-carrying capacity and energy-absorption capability than kenaf fibre.
