Problems solved by technology

[0003] In view of the above-mentioned problems, the present invention proposes a method for preparing a prefabricated skeleton integrally formed composite material shelter. The prepared composite material shelter has good continuity of the inner and outer skins, which overcomes the traditional metal skeleton type shelter structure and The large-slab type shelter has the disadvantages of complex structural procedures and weak mechanical properties at the combined joints, and the shelter has better airtightness, durability, and lighter weight. At the same time, through functionalization such as hard foam, it can also endow the shelter with stealth and electromagnetic shielding. And impact resistance, etc., to better meet the high-performance requirements of military and civilian dual-use command systems, communications, medical care, logistics support and other fields

Abstract

The invention provides a preparation method of a prefabricated framework type integrally-formed composite square cabin. The preparation method includes the following steps that a square cabin framework system is prepared from prefabricated carbon fiber parts, prepreg is adopted as a square cabin skin material, rigid foams are adopted as a filling material, and under the assistance of a combined die, in a vacuum bag pressing manner, the composite square cabin is prepared at a certain temperature through integral forming. The continuity of inner skin and outer skin of the square cabin is good, the defects that a traditional metal framework type square cabin structure and a large plate type square cabin structure are complex in procedure, and the mechanical performance of combined joints is weak are overcome, and the square cabin is better in sealing performance and durability and lighter; and meanwhile, through the rigid foam and other functionalization, the square cabin can be embodiedwith the beneficial effects of being invisible, having shielding electromagnetism, being resistant to impact and the like, and the high-performance requirements in the fields such as military and civilian dual-use commanding systems, communication, medical treatment and logistical support are better met.

Description

technical field [0001] The invention relates to the technical field of composite material shelters, in particular to a method for preparing a prefabricated skeleton integrally formed composite material shelter. Background technique [0002] Traditional metal frame shelters or large slab shelters have complicated structural procedures, weak mechanical properties at combined joints, and are relatively weak in terms of airtightness and durability; and the existing shelters are not well functional. Relatively weak, such as stealth, electromagnetic shielding and impact resistance, etc., limit the application fields of the shelter. There is an urgent need in the market for lighter weight and better mechanical properties, which can better meet the high-performance requirements of military and civilian dual-use command systems, communications, medical care, and logistics support. Contents of the invention [0003] In view of the above-mentioned problems, the present invention pro...
