MULTI-LAYERED HOLLOW TEXTILE MATERIAL, MULTI-LAYERED HOLLOW TEXTILE COMPOSITE MATERIAL AND METHOD OF PRODUCING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a multi-layered hollow textile material with light weight and a sufficient strength in a direction orthogonal to an oriented direction of fiber structure sheet capable of producing with a simple method by use of the conventional loom and knitting machine and a method of producing the same, and to provide a multi-layered hollow textile composite material in which the multi-layered hollow textile material is filled with a resin and a method of producing the same.

SOLUTION: A multi-layered hollow textile material comprises: a first fiber structure sheet 1a; a second fiber structure sheet 1b; at least one intermediate fiber structure sheet 1c arranged between the first and the second fiber structure sheets 1a, 1b; and a connecting yarn 2 inserted from the first fiber structure sheet 1a to the second fiber structure sheet 1b by way of the intermediate fiber structure sheet 1c, in which the first fiber structure sheet 1a, the second fiber structure sheet 1b and the intermediate fiber structure sheet 1c are arranged with a prescribed gap as opposed to each other to define a space 3 for filling resin between each fiber structure sheet 1.
