FRP honeycomb sandwich constructions are light and high rigidity members which have a good corrosion resistance. These constructions have been by many different molding methods and used for many appliances. So in this paper, we have examined the practical properties of FRP honeycomb sandwith construations which are used for underground laid application. The practical properties examined were alkali (pH 12) resistance, the dependence of heat circumstance and freezing-hot water (60℃) heat cycle resistance. Especially fracture pattern and mechanism were considered in testing of alkali resistance. The results obtained confirmed that FRP honeycomb sandwich can be applied for the structural members of underground laid uses. From the flexural test after dipping test of high alkali solution, it was clarified that there are different fracture patterns (one or both side fracture of facing, shearing fracture of core and combination fracture of facing and core) of FRP honeycomb sandwich constructions.
