AN ANALYSIS ON THE FRICTIONAL PROPERTY AND LONG-TERM PERFORMANCE OF GT/HDPE COMPOSITES

초록

As for polypropylene non-woven GT more efficient in terms of long-term performance, they have some problems in durability when exposed to alkali or ultraviolet in higher temperature. In addition, when such additives as carbon black and anti-oxidant are mixed with polypropylene to improve stability against ultraviolet, it may entail the problem of manufacturing cost more increasing and becoming more difficult to produce textiles than polyester. Besides this, polypropylene or polyester GT are installed upon the HDPE GM in the waste landfill and frictional property between these is the cause of long-term performance decrease of these geosyntheics [1]. To take into this consideration, this study is to develop high performance GT composites with GM by using PVA GT to be capable of improving frictional property, chemical and ultraviolet stability etc.
