Title:
COMPOSITE MATERIAL HAVING THREE-DIMENSIONAL STRUCTURE
Document Type and Number:
Japanese Patent JP2714755
Kind Code:
B2
Abstract:
PURPOSE: To obtain a composite material having a three-dimensional structure lightweight and easy to handle even if thickness is relatively large and suitably usable in various industrial fields while putting characteristics such as air permeability or water permeability due to internal gaps to practical use by constituting a layer holding thickness using a net having a three-dimensional structure.
CONSTITUTION: A sheet like article 2 having or not having air and water permeability is bonded to the single surface or both surfaces of a net 1 wherein string parts 12 demarcating mesh holes 11 form an air and water permeable substantially hollow three-dimensional structure. The net 1 is formed by braiding or weaving synthetic fiber yarns or the like and proper elasticity or flexibility is provided to the string parts 12. An air and water permeable gap holding material is held in the string parts 12.
