Abstract
PURPOSE: To prevent fibers from penetrating into a core body by a method wherein a fibrous net-formed body or the like produced by impregnating a fibrous material with a resin and hardening the resin in such a manner as not to lose water permeability is provided on the surface of a core body which is provided with longitudinal grooves, in the titled support used for converting sea water into fresh water or other similar purpose.
CONSTITUTION: A hollow or solid core body made of a synthetic resin, FRP, a metal, a ceramic or the like is provided with parallel or spiral grooves in the longitudinal direction at the surface. On the surface of the core body is provided a layer of the fibrous net-formed body, a woven fabric or a nonwoven fabric which is produced by impregnating the fibrous material with a resin and hardening the resin in such a manner as not to spoil the water permeability. When impregnating the fibrous material with the resin and hardening the resin, it is suitable to use the resin and the fibrous material in a weight ratio of 1:100W1:2, preferably 1:20W1:4 in order not to substantially spoil the water permeability of the fibrous material.
