Abstract
Low density polyethylene composites filled with fiberglass of two forms were used for the studies. The role of continuous fiber and discontinuous fiber in reinforced plastics composite was experimentally investigated. The results indicated that the tensile strength of low density polyethylene composite filled with continuous fiberglass was in good agreement with Hollister''s theory, and those filled with discontinuous fiberglass showed about one half of the theoretically predicated strength values. When the surface of fiberglass was pretreated by N-β-amino ethyl-γ-amino propyl trimethoxy silane, in the plotted range of volume fraction up to 10%, the strength was higher than the theoretical value.

Polymer matrix는 Low Density polyethylene을 사용하고 fiberglass를 일방향으로 배열하여 복합시켰다. 그 결과 fiberglass의 복합소재가 continuous fiber일 때는 Hollister의 이상이론치와 거의 일치했고 discontinuous fiber일 때는 이론치의 대략 1/2 정도인데 이는 High Density polyethylene의 경우보다 좋은 값을 보여준다. 또한 N-β-aminoethyl-γ-aminopropyl trimethoxy silane으로 fiberglass를 처리했을때 10%까지의 용적범위에서는 이론치보다 다소 상회하는 결과를 얻었다.
