초록

본 연구에서는 급속히 성장하고 있는 산업분야인 생분해성 플라스틱인 PLA(Poly Lactic Acid)를 사용하여 개발된 식생매트의 생분해기간에 따른 인장성능을 비교하였다. 시험방법은 한국산업표준(KS)에서 정한 방법을 준용하였다. 단일소재로 제작된 PLA 매쉬 및 PLA 플라스틱으로 실험한 두꼐, 인장강도 및 분자량은 5개월 생분해 기간에 반비례하는 결과를 나타내었다. PLA 매쉬의 두께는 11.2%~13.4% 수준까지 두께가 증가하였으며 PLA 매쉬의 인장강도는 32.4%~55.4% 수준까지 감소하였다. PLA 플라스틱의 인장강도 및 분자량도 시간경과에 따라 감소하는 것을 확인할 수 있었다. 다만, PLA 매쉬, 부직포(씨앗포함) 및 황마네트로 혼합 구성된 식생매트의 인장시험결과는 특정한 경향성을 보이지 못하였다.

This research compared the tensile performance of the vegetation mat, which was developed byu using the rapidly growing biodegradable plastic, Poly Lactic Acid(PLA), according to the biodegradation period. The test applied the method defined by Korean Standard KS. In the result of experiment using single-material PLA mesh and PLA plastic, the tensile strength and molecular weight were inverse-proportional to the 5 months of biodegradation period. The thickness of PLA mesh was increased by 11.2~13.4% while the tensile strenth of it was reduced by 32.4~55.4%. The tensile strength and molecular weight of PLA plastic were also reduced over time. However, the tension test of vegetation mat comprised of PLA mesh, non-woven fabric (including seeds), and jute net didn't have specific tendency.
