Abstract

The Aluminum conductor composite core consists of fast-curing thermosetting epoxy used as reinforcements and carbon fiber and glass fiber used as matrix. In this study, we have investigated fast curing epoxy cured products used for composite core(Aluminum Conductor Composite Core, ACCC). Tetrafunctional epoxy(PA 806) was used as a multifunctional epoxy, along with two kinds of curing agents, MNAn(5-Methyl-5-norbornene-2,3-dicarboxylic anhydride) and HHPA(Hexahydrophthalic Anhydride), to make an epoxy cured product and their properties were evaluated. Optimum conditions are confirmed by varying the content of curing accelerator in the selected epoxy and curing agent.

복합재료 중심인장선의 구성은 강화재로 사용되는 탄소섬유 및 유리섬유와 기지재로 사용되는 속경화 열경화성 에폭시로 되어있다. 본 연구에서는 가공송전선의 복합소재 중심인장선(ACCC)에 사용되는 에폭시 경화물에 대하여 분석하였다. 다관능성 에폭시 중 4관능성 에폭시(PA 806)을 사용하고 MNAn, HHPA 두가지 경화제 및 경화 촉진제를 사용하여 에폭시 경화물을 만들고 이를 분석하였다. 경화제의 종류 및 경화 촉진제의 함량에 따른 최적조건을 도출하였다.
