초록

폐FRP 선박을 재활용하는 기술은 많은 발전을 이루어왔으며 최근에는 가장 재활용도가 적은 부분인 유리섬유의 고부가치화 재활용이 특히 주목받고 있다. 폐FRP 선박의 재처리 과정에서 추출된 유리섬유는 피막된 수지 성분의 내화학성으로 인하여 섬유보강재로서 사용 가능하다는 것이 보고되었다. 그러나 섬유보강재(laminated glass fiber reinforced material)를 추출하는 공정의 효율성과 경제성의 재고는 개선되어여할 과제이다. 본 연구는 다층구조인 FRP로부터 면포층(robin cloth layer)을 보다 효과적으로 박리할 수 있는 방법을 제시하여 추출공정의 최적화를 도모하고자한다. 새로운 추출공정에서 생산된 섬유보강재를 활용한 섬유강화콘크리트(Fiber Reinforced Concrete, FRC)의 강성은 매우 우수한 것으로 관찰되었다.

영어초록

There is several ways of recycling methods for waste FRP boats. The main one is mechanical
recycling that is one of the simple and technically proven methods. It recently has been reported that FRP
can be recycled by separating into laminated glass fiber layers instead of crushing into powder. Even though
the mechanical recycling is a good way for the eligibility of laminated glass fiber reinforced material, the
system should have another option which can collect resin of FRP. Because the resin is still very useful
renewable energy source, that cannot be discarded, But FRP is made up of laminated glass fiber (roving cloth
layer) which is fire retardant substances and very hard to break into each layer. Due to the high cost of fossil
energy the waste plastics should be regenerated to the source of renewable energy. Laminated glass fiber
which is recyclable in a very limited way, is currently a serious barrier to waste FRP boat regenerating. This
study is to propose a new extracting method which is efficient and environment friendly FRP waste regenerating
system. The recycled glass fiber which is obtained by the separation of the roving layer from FRP
waste has been found to be useful for concrete(FRC) products or concrete(FRC) structures as fiber reinforced
material. And it can be successively applied to renewable energy applications using the waste resins of FRP
residue without laminated glass fiber.
