In the present work, multi-walled carbon nanotubes (MWCNT) were anchored with the assistance of vinyl ester resin (VE) on the carbon fiber surfaces of conventional carbon fabrics (CCF) and semi-spread carbon fabrics (SSCF) having different areal density, ply thickness, and crimp number, respectively. Here, MWCNT anchoring means that MWCNT were physically attached on the individual carbon fiber surfaces of each fabric by coating with dilute VE and then by thermally curing it. The MWCNT anchoring effect on the interlaminar shear strength (ILSS) of CCF/VE and SSCF/VE composites was investigated. MWCNT were also simply applied (without physical attachment) to the carbon fiber surfaces of CCF and SSCF for comparison, respectively. It was found that SSCF/VE composites exhibited the ILSS higher than CCF/VE composites, regardless of simple-applying or anchoring of MWCNT, increasing the ILSS with the MWCNT concentration. It was noted that MWCNT anchoring was effective to improve not only the interlaminar adhesion but also the interfacial bonding between the carbon fiber and the matrix due to the formation of MWCNT bridges between the individual carbon fibers of SSCF, indicating that the MWCNT anchoring effect was more pronounced with SSCF than with CCF. The result of the interlaminar property was well supported by the fiber and composite fracture topography.

선박금융 의사결정에서 해운기업들은 비합리적인 의사결정을 선택하는 경우가 있으며, 이러한 결과는 해운기업들에 막대한 손실을 유발시킨다. 이러한 선박금융 의사결정 선택에 대한 분석을 본 연구는 행동재무학 이론 중 엥카링 효과와 매몰 비용 효과 이론으로 접근 하였으며, 설문지법과 사례 분석 방법론으로 논문을 작성하였다. 분석 결과, 행동재무학 이론인 엥카링 효과와 매몰 비용 효과가 선박금융 의사결정에 영향을 미친다는 사실과 이러한 영향으로 의사결정자가 비합리적인 의사결정을 선택하게 될 수 있다는 사실을 발견했다.
