Problems solved by technology

For field storage, it is necessary to prevent the corrosion and aging of various corrosive media in nature on the outside of the storage envelope. However, there are still some disadvantages in the external storage envelope: 1. The surface of the storage device and weapon is easy to be corroded; 2. The strength of the storage envelope is low. The tip of the weapon is prone to punctures and tears, causing water vapor to leak out

Abstract

The invention discloses a weaponry field sealing and storage envelope, a composite material for a weaponry field sealing outer package and a preparation method of the composite material. The composite material for the weaponry field sealing outer package sequentially comprises an anti-corrosion layer, a first bonding layer, a high-barrier layer, a second bonding layer, a base material layer, a third bonding layer and a heat sealing layer from top to bottom; the anti-corrosion layer is made of an organic silicon resin composite material, the high-barrier layer is made of one of aluminum foil or PVDC, the base material layer is made of a carbon fiber reinforced composite material, and the heat sealing layer is made of a TPU material. The field sealing envelope prepared from the composite material is light in weight and soft, and is not rusted, not deteriorated and not reduced in performance in a specified sealing period under the condition that the field storage environment condition is extremely severe, and the field sealing envelope plays an important role in improving the storage reliability of an airplane, prolonging the service life and improving the guarantee capability of equipment.

Description

technical field [0001] The invention belongs to the material field of military equipment field storage envelopes, and in particular relates to a weapon equipment storage envelope, a composite material used for the weapon equipment field storage outer packaging, and a preparation method. Background technique [0002] At present, the update speed of weapons and equipment (such as aircraft, etc.) is getting faster and faster, and some weapons and equipment will be decommissioned. The eliminated weapons and equipment are not scrapped, but sealed up. Immediately put into use, the second is to serve as a "spare library" for equipment in service; the third is to use it for other purposes. The United States seals up obsolete weapons and equipment and stores them in special places, and takes them out when needed. The purpose is to reduce maintenance costs, save weapon investment, extend the service life of weapons, and ensure that weapons are ready for combat at any time. For examp...
