Abstract
The invention relates to a missile launcher technology. In order to solve the problems of easy embrittlement during long-term storage of an easily-cracking front cover and potential safety hazards due to a large quantity of fragments after the cover is broken after launched, the invention provides a composite easily-cracking front cover opened in one side and a making method of the composite easily-cracking front cover. Compared with the prior art, the composite easily-cracking front cover has the advantages and the beneficial effects of light weight, high strength and good compaction due to the adoption of a composite, and can ensure that the front cover structure is more reasonable in performance and is greatly improved in sealing property; and made by adopting a mold, the composite easily-cracking front cover has the advantages of capability of effectively controlling precision and ensuring that cover breaking pressures are consistent, rapidness, high efficiency and stable quality; and an opened cover body can not be separated from the launcher so as to eliminate potential safety hazard caused by scattering broken fragments after the cover is opened. The composite easily-cracking front cover is formed through medium-temperature curing, can be reliably used under the condition of high-temperature and low-temperature environments, and is difficult in embrittling and cracking.
Description
Technical field
The present invention relates to the launch canister technology, the protecgulum of the MISSILE LAUNCHING case of especially making of composite can make and easily split the protecgulum list and survey and open and do not come off.
Background technology
Protecgulum is as launching tube (case) important composition parts, and the reliability of guided missile storage life-span, use and maintenance and emission is had a direct impact.Fast development along with the MISSILE LAUNCHING technology, require that launching tube (case) is front to be stamped certain strength and stiffness, have again good air-tightness, electromagnetic wave shielding and ablation resistance etc., in addition, also require its convenience of uncapping, reliable, do not affect the guided missile normal transmission.In recent years, adopt nonmetallic materials to replace metal material, with frangible lid or easily split lid replacement mechanical type and uncap and become the new developing direction of MISSILE LAUNCHING technology.Nonmetal protecgulum comprises frangible lid and easily splits and covers two classes.Frangible protecgulum mostly is polyurethane or the epoxy foam material is made, and the easy embrittlement of long term storage produces a large amount of fragments behind the broken lid of emission, can damage ground staff and equipment, has potential safety hazard.
Summary of the invention
Purpose of the present invention provides a kind of composite of one-sided unlatching easily to split protecgulum and preparation method, can be in launching tube internal combustion inflatable broken or bullet open when breaking through one-sidedly, the lid after opening can be realized not separating with launching tube.
In order to reach the foregoing invention purpose, the present invention realizes by following technical scheme, a kind of composite of one-sided unlatching easily splits protecgulum, comprise front cover body, also comprise steel wire, slip-off preventing hold-down screw, steel wire is located at front cover body one side, and the one end is connected with protecgulum by the slip-off preventing hold-down screw, and other end glue is on front cover body.Front cover body can be in launching tube internal combustion inflatable broken or bullet open when breaking through, the lid after opening can be realized not separating with launching tube.
A kind of composite of making one-sided unlatching easily splits the method for protecgulum, comprises the steps:
Step 1, select epoxy. amine/Woven glass cloth, glass/epoxy Prepreg and Kevlar fiber/epoxy Prepreg composite is as lid;
Step 2, with epoxy. amine/Woven glass cloth, glass/epoxy Prepreg and Kevlar fiber/epoxy Prepreg compound material laying applies on formpiston, carry out the laying of cover body structure layer, the local enhancement place uses without latitude cloth and steel wire shop and applies, and it is definite according to design that material spreads the number of plies and the direction of applying;
Fit when step 3, yin, yang mould matched moulds and with the die joint position, overfall has glue to flow out;
Step 4, mould are put into the curing oven intermediate temperature setting;
Step 5, dismounting yin, yang mould carry out the lid finishing, remove burr, process lid and cover frame, pressing plate for sealing contact-making surface.
Be 3 hours described hardening time, and temperature is 120 ℃.Can guarantee that goods reliably use under the high and low temperature environment
The present invention compared with prior art, its advantage and beneficial effect are:
Adopt composite, high-strength light, density are good, can guarantee that the front-cover structure performance is more reasonable, and sealing property improves greatly; Adopt Mold Making, can effectively control the goods precision, guaranteeing goods, broken to cover pressure consistent, rapidly and efficiently, steady quality; Lid after opening can be realized not separating with launching tube, eliminates the potential safety hazard that the rear fragmentation of uncapping is scattered and causes.
The intermediate temperature setting moulding can guarantee that goods reliably use under the high and low temperature environment, be difficult for the embrittlement cracking.Break through and dynamically burst and experiment showed, that composite of the present invention easily splits protecgulum and can meet the demands by protecgulum.
Description of drawings
The present invention is further detailed explanation below with reference to drawings and Examples.
