Abstract

Lightweight hydrant tanks increase the amount of water that can be carried by fire trucks, resulting in longer water spray times during the initial firefighting process, which can minimize human and property damages. In this study, the applicability of carbon-fiber-reinforced polymer (CFRP) composites as a material for lightweight hydrant tanks was investigated. In particular, the resin for manufacturing CFRP hydrant tanks must meet various requirements, such as excellent mechanical properties, formability, and dimensional stability. In order to identify a resin that satisfies these conditions, five commercially available resins, including epoxy(KFR-120V), unsaturated polyesters(G-650, HG-3689BT, LSP8020), vinyl ester(KRF-1031) were selected as candidates, and their characteristics were analyzed to investigate the suitability for manufacturing a CFRP hydrant tank. Based on the analyses, KRF-1031 exhibited the most suitable properties for hydrant tanks. Particularly, CFRP with KRF-1031 exhibited successful results for thermal stability and elution tests


소화전 탱크의 경량화는 소방차가 수용할 수 있는 물의 양을 증가시켜 초기 소방 과정에서 물 분무 시간을 늘려 화재로 인한 재산과 인명 피해를 크게 줄일 수 있다. 본 연구에서는 탄소섬유강화폴리머(CFRP) 복합재료를 경량 소화전 탱크의 재료로 적용하는 것을 조사하였다. CFRP 소화전 탱크 제조를 위해 사용되는 수지는 우수한 기계적 물성, 성형성, 치수안정성 등 여러 조건들을 만족시켜야 한다. 위의 조건들을 만족시키는 수지를 찾기 위해 KFR-120V, G-650, HG-3689BT, LSP8020, KRF-1031 등 5가지 수지를 후보로 선정하고 테스트하여 CFRP 소화전 탱크 제조 적합성을 조사였다. 분석 결과 KRF-1031이 소화전 탱크에 가장 적합한 특성을 보였다. 특히, KRF-1031을 이용한 CFRP는 열안정성 및 용출 시험에서 성공적인 결과를 보였다.
