초록

본 연구에서는 하이브리드 가스 발생기용 파라핀/알루미늄 왁스 연료의 기계적 특성 파악을 위한 인장 및 압축강도 실험을 수행하였다. 혼합된 알루미늄 입자의 크기와 첨가량에 따른 기계적 특성을 파악하기 위해 10 wt%, 20 wt%, 30 wt%의 나노 입자 첨가 시편과 5 wt%, 10 wt%, 15 wt%의 마이크로 입자 첨가 시편을 사용하였다. 평균입도 100 nm 및 $8{\mu}m$ 크기의 알루미늄 입자와 Sasol사의 미정질 파라핀 왁스(Sasol 0907)를 이용하였고, 인장시험과 압축 시험에 사용된 시편은 각각 ASTM-D638, ASTM D575-91 규격에 따라 제작하였다. 나노 입자의 첨가는 시편의 인장 및 압축강도를 크게 향상시키나 마이크로 입자의 첨가는 상대적으로 인장 및 압축강도의 증가에 미치는 영향이 미미한 것으로 파악되었다.

Tensile and compressive strength tests were conducted to investigate the mechanical characteristics of aluminized paraffin wax fuel for hybrid gas generator applications. Mixtures of 0 wt%, 10 wt% and 30 wt% nano aluminum paraffin coupons as well as 5 wt%, 10 wt% and 15 wt% micro aluminum paraffin coupons were used. The average particle size of 100nm and of $8{\mu}m$ mixed each with microcrystalline paraffin wax(Sasol 0907) were chosen for the base specimens where the tensile strength test followed the ASTM-D638 specimen standard while the compressive strength test followed the ASTM D575-91. It was found that nano based specimens increased both the tensile and compressive strength enhancing the mechanical behavior of paraffin wax whereas the micro based specimens gave still less influential effect.
