Embodiment Construction

[0017] The present invention is further described below:

[0018] A composite fabric with a sandwich sandwich structure containing a polyurethane film layer used in space suits is characterized in that the composite fabric is a sandwich sandwich structure of polyurethane film layer / bonding agent / cloth.

[0019] Be specifically related to a kind of airtight layer fabric of outer suit of spaceflight, have the sandwich interlayer structure of polyurethane film layer / bonding agent / cloth, embodiment: used raw material is as follows: nylon silk cloth (DB327 silk cloth, Jiangsu Dongbang Science and Technology Co., Ltd.), Bonding agent (DB1101, Jiangsu Dongbang Technology Co., Ltd.), TPU film PUF1151, Jingjia Lianchuang Material Technology Co., Ltd.). The lamination process preparation process is as follows:

[0020] ① Film feeding PUF1151: film feeding requires no tension, and the film must be sent flat on the conveyor belt. lead to poor fit or no fabric at all);

[0021] ②Glue ap...

Abstract

A sandwich-structured composite fabric with a polyurethane film layer and applied to spacesuits is characterized in that the composite fabric is in a sandwich structure formed by a polyurethane film layer, a lap joint agent and cloth. The sandwich-structured composite fabric with the polyurethane film layer and applied to the spacesuits is provided so as to meet requirements on pressure maintaining and shape keeping of an airtight layer and is capable of effectively improving tear strength to meet requirements on aging resistance, high abrasion resistance, pierce resistance, tear resistance, high reliability and high service life.

Description

technical field [0001] The invention relates to the field of textile fabrics, in particular to a composite fabric with a sandwich sandwich structure containing a polyurethane film layer used in space suits. Background technique [0002] Space suit), especially the extravehicular space suit (Extar Mobility Unit, EMU), is called the "life talisman" of astronauts. It is a comprehensive protection system made of special materials, with multi-level, multi-module, multi-functional Features. Aviation suits have evolved from generation to generation. It also showed the concept products of space suits with futuristic colors, which are used for the exploration of the moon and Mars. In addition to functions such as cold protection, shock absorption, radiation resistance, and impact resistance, space suits also need to maintain a constant and stable positive air pressure, which is mainly played by the pressure garment bladder. The mainstream structure of space suits is a multi-layer ...
