EMI shielding effectiveness and mechanical properties of MWCNTs-reinforced biodegradable epoxy matrix composites
Yoon-Ji Yim, Dong Chul Chung, Soo-Jin Park 한국탄소학회 Carbon Letters 6 Pages
한국탄소학회 Carbon Letters 2017, Vol.22 4 36-41 (6 pages)
of B-epoxy composites reinforced with multi-walled carbon nanotubes (MWCNTs/B-epoxy) were examined by employing dynamic mechanical analysis, critical stress intensity factor (KIC) tests, and impact strength tests. The electromagnetic interference shielding effectiveness (EMI-SE) of the composites was evaluated using reflection and absorption methods. Mechanical properties of MWCNTs/B-epoxy were enhanced with an increase in the MWCNT content, whereas they deteriorated when the MWCNT content was... -

Flexural, electrical, thermal and electromagnetic interference shielding properties of xGnP and carbon nanotube filled epoxy hybrid nanocomposites
Young Sil Lee, Yeon Ho Park, Kwan Han Yoon 한국탄소학회 Carbon Letters 6 Pages
한국탄소학회 Carbon Letters 2017, Vol.24 6 41-46 (6 pages)
(EMI) shielding effectiveness (SE) of epoxy composites filled with multi-walled carbon nanotubes (CNTs), exfoliated graphite nanoplatelets (xGnPs) and CNT-xGnP hybrid filler were investigated. The EMI SE of the CNT-xGnP hybrid composite was higher than 25 dB at 100 MHz while that of the xGnP based composite was almost zero. The flexural modulus of the CNT-xGnP based epoxy composite continuously increased to 3.32 GPa with combined filler content up to 10 wt% while that of the CNT based epoxy... -
통신케이블 차폐시험방법의 유효성 확인 및 측정불확도 추정
김종상, 조남호 한국컴퓨터정보학회 한국OA학회논문지 12 Pages
한국컴퓨터정보학회 한국OA학회논문지 2002, Vol.7 No.1 8-19 (12 pages)
시험기관은 표준화되지 않은 시험방법. 해당기관이 설계/개발한 방법 등에 의한 시험을 수행할 경우 방법의 유효성이 확인되어야만 사용할 수 있으며, 또한 측정값에 대한 불확도(Uncertainty)의 추정이 요구되고 있다. 따라서 케이블-하네스의 EMI 차폐효과시험방법에 대한 측정정밀도를 통계적 분석 방법 에 의거 검토하여 유효성을 확인하는 방법을 제시하고 시험결과에 대한 측정불확도를 추정하는 방법을 제시하였다.
