Recently, UAVs (unmanned air vehicles) have been developed with high performance, and hence, the range of system utilizing has also widening. are even considered as connected mobile sensors claimed to be future IoT (Internet Things). UAVs’ mission fulfillment is relying on efficiency performance communication in a FANET (Flying Ad hoc NETwork) environment where communicate each other through an ad network without infrastructure. Especially, for mission-critical applications such disaster...
In no-insulation (NI) REBCO coils, thermal contact resistance (TCR) between winding turns has important influence on stability of magnets under varying magnetic field or even in case quench. Reduction TCR is one the crucial factors to develop thermally stable cooled by conduction. To avoid a delamination problem, epoxy not usually used and significant exists NI magnets. Then, thin layers coil surfaces metallic conduction plates are enhance design conduction, TCR, induced dry contacts turns,...
이 연구에서는 녹차와 목재섬유를 복합한 친환경 복합보드를 건축내장재로 활용하기 위하여, 목재섬유에 대한 녹차의 배합비율을 달리한 녹차-목재섬유 제작하였고, 복합보드의 동적탄성률에 미치는 배합비율 및 바인더로 사용한 접착제의 영향을 조사하였다. 녹차-목재섬유복합보드의 동적탄성률은 녹차를 넣지 않은 대조보드(control boards)의 그것보다 적었고, 녹차배합비율이 증가할수록 커지는 경향을 나타내었다. 또한, 보드제조에 사용된 바인더의 종류에 따라 동적탄성률의 차이가 나타났는데, <TEX>$E_1$</TEX>급의 요소수지가 <TEX>$E_0$</TEX>급의 요소수지보다 1.06~1.54배의 높은 값을 나타내었으며, 배합비율이 커질수록 양자의 차이는 것이 확인되었다. 한편, 동적탄성률과 휨 강도성능과는 비교적 상관관계가 확인되어 일부 편차가 큰 조건을 제외하고 동적탄성률로부터 정적 강도성능의 예측이 가능할 것으로 In this study, eco-friendly hybrid...
