이 글에서 우리는 메를로-뽕띠(1908-1961)의 철학에 있어서 <존재론적 전 회>를 주도했던 저자의 꼴레주 드 프랑스에서의 자연강의(1956-1960)가 어떤 의미 에서 전통적 주체개념과 관련하여 완전히 새로운 사유의 지평을 열었는지를 밝히 고자 한다. 주지하듯이 주체개념은 메를로-뽕띠의 철학에 있어서 시종일관 사유의 중심에 위치한 문제였다. 따라서 그 개념은 지각에 대한 그의 사유가 전개, 심화되 어감에 따라 가장 큰 의미변형을 겪은 개념들 중의 하나다. 자신의 최초의 철학적 기획이었던 지각 현상학이 점점더 그 분명한...

Effects of maleic anhydride content on mechanical properties of carbon fibers-reinforced maleic anhydride-grafted-polypropylene matrix composites
Hyun-Il Kim, Woong Han, Woong-Ki Choi, Soo-Jin Park, Kay-Hyeok An, Byung-Joo Kim 한국탄소학회 Carbon Letters 8 Pages
한국탄소학회 Carbon Letters 2016, Vol.20 6 39-46 (8 pages)
In this work, the effects of maleic anhydride (MA) content on mechanical properties of chopped carbon fibers (CFs)-reinforced MA-grafted-polypropylene (MAPP) matrix composites. A direct oxyfluorination on CF surfaces was applied to increase the interfacial strength between the CFs and MAPP matrix. The mechanical properties of the CFs/MAPP composites are likely to be different in terms of MA content. Surface characteristics were observed by scanning electron microscope, Fourier transform infrared... -
Phenylethynyl-terminated polyimide, exfoliated graphite nanoplatelets, and the composites: an overview
Donghwan Cho, Lawrence T. Drzal 한국탄소학회 Carbon Letters 11 Pages
한국탄소학회 Carbon Letters 2016, Vol.19 1 1-11 (11 pages)
In efforts to characterize and understand the properties and processing of phenylethynyl-terminated imide (LaRC PETI-5, simply referred to as PETI-5) oligomers and polymers as a high-temperature sizing material for carbon fiber-reinforced polymer matrix composites, PETI-5 imidization and thermal curing behaviors have been extensively investigated based on the phenylethynyl end-group reaction. These studies are reviewed here. In addition, the use of PETI-5 to enhance interfacial adhesion between... -
Effects of cross-linking methods for polyethylene-based carbon fibers: review
Kwan-Woo Kim, Hye-Min Lee, Jeong-Hun An, Byoung-Suhk Kim, Byung-Gak Min, Shin-Jae Kang, Kay-Hyeok An, Byung-Joo Kim 한국탄소학회 Carbon Letters 24 Pages
한국탄소학회 Carbon Letters 2015, Vol.16 No.3 2 147-170 (24 pages)
In recent decades, there has been an increasing interest in the use of carbon fiber reinforced plastic (CFRP) in aerospace, renewable energy and other industries, due to its low weight and relatively good mechanical properties compared with traditional metals. However, due to the high cost of petroleum-based precursors and their associated processing costs, CF remains a specialty product and as such has been limited to use in high-end aerospace, sporting goods, automotive, and specialist...
