Abstract
The present invention relates to launch canister technology, for solving the easy embrittlement of frangible protecgulum long storage periods, a large amount of fragment can be produced after launching broken lid, there is potential safety hazard, the composite that the invention provides a kind of one-sided unlatching easily splits protecgulum and preparation method, compared with prior art, its advantage and beneficial effect are: adopt composite, high-strength light, density are good, and can ensure that front-cover structure performance is more reasonable, sealing property improves greatly; Adopt Mold Making, can effectively control goods precision, ensure that goods break lid pressure consistent, rapidly and efficiently, steady quality; Lid after opening can realize not being separated with launching tube, eliminates fragmentation after uncapping and to be scattered the potential safety hazard caused.Intermediate temperature setting is shaping, can ensure that goods reliably use under high and low temperature environment, not easily brittle cracking.
Description
Technical field
The present invention relates to launch canister technology, especially with the protecgulum of the MISSILE LAUNCHING case of composite making, can make easily to split protecgulum list and survey unlatching and do not come off.
Background technology
Protecgulum, as launching tube (case) important composition parts, has a direct impact the reliability of guided missile storage life-span, use and maintenance and transmitting.Along with the fast development of MISSILE LAUNCHING technology, require that launching tube (case) is front and be stamped certain strength and stiffness, there are good air-tightness, electromagnetic wave shielding and ablation resistance etc. again, in addition, also require that it is uncapped conveniently, reliably, does not affect guided missile normal transmission.In recent years, nonmetallic materials are adopted to replace metal material, with Fragile cap or easily split lid and replace mechanical type to uncap and become the new developing direction of MISSILE LAUNCHING technology.Nonmetal protecgulum comprises Fragile cap and easily splits lid two class.Frangible protecgulum mostly is polyurethane or epoxy foams makes, the easy embrittlement of long storage periods, produces a large amount of fragment, can damage, there is potential safety hazard to ground staff and equipment after launching broken lid.
Summary of the invention
Object of the present invention provides a kind of composite of one-sided unlatching easily to split protecgulum and preparation method, and can open one-sided when launching tube internal combustion inflatable is broken or bullet breaks through, the lid after opening can realize not being separated with launching tube.
In order to reach foregoing invention object, the present invention is realized 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, front cover body side is located at by steel wire, and its one end is connected with protecgulum by slip-off preventing hold-down screw, and other end glue is on front cover body.Front cover body can be opened when launching tube internal combustion inflatable is broken or bullet breaks through, and the lid after opening can realize not being separated with launching tube.
The composite making one-sided unlatching easily splits a method for protecgulum, comprises the steps:
Step 1, select epoxy. amine/Woven glass cloth, glass/epoxy Prepreg and Kevlar fiber/epoxy Prepreg composite are as lid;
Step 2, by 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, local enhancement place is applied with without latitude cloth and steel wire paving, and the number of plies that material paving is applied and direction are determined according to design;
When step 3, yin, yang mould matched moulds and by die joint position fit, overfall has glue to flow out;
Curing oven intermediate temperature setting put into by step 4, mould;
Step 5, dismounting yin, yang mould, carry out lid finishing, remove burr, process lid and cover frame, pressing plate for sealing contact surface.
Described hardening time is 3 hours, and temperature is 120 DEG C.Can ensure that goods reliably use under high and low temperature environment
Compared with prior art, its advantage and beneficial effect are in the present invention:
Adopt composite, high-strength light, density are good, and can ensure that front-cover structure performance is more reasonable, sealing property improves greatly; Adopt Mold Making, can effectively control goods precision, ensure that goods break lid pressure consistent, rapidly and efficiently, steady quality; Lid after opening can realize not being separated with launching tube, eliminates fragmentation after uncapping and to be scattered the potential safety hazard caused.
Intermediate temperature setting is shaping, can ensure that goods reliably use under high and low temperature environment, not easily brittle cracking.Being broken through by protecgulum and dynamically bursting experiment is proved, composite of the present invention easily splits protecgulum and can meet the demands.
Accompanying drawing explanation
Below with reference to drawings and Examples, the present invention is further detailed explanation.
Fig. 1 is that the composite of the one-sided unlatching of the present invention easily splits front-cover structure figure;
Fig. 2 is the front cover body local enhancement structure chart of Fig. 1.
In figure: screw 1, pressing plate 2, lid 3, cover frame 4, sealing ring 5, broken lid direction signal 6, lid thickening layer 7, steel wire 8, slip-off preventing hold-down screw 9.
Detailed description of the invention
As shown in Figure 1, be that the composite of one-sided unlatching easily splits protecgulum, in figure, protecgulum comprises screw 1, pressing plate 2, lid 3, cover frame 4, sealing ring 5, broken lid direction signal 6, lid thickening layer 7, steel wire 8, slip-off preventing hold-down screw 9.Sealing ring 5 is loaded in cover frame 4, then lid 3 is put into the cover frame 4 li being coated with polysulfide sealant, with pressing plate 2 lid fastened and by screw 1, lid 3, cover frame 4, pressing plate 2 locked.
As shown in Figure 2, be front cover body local enhancement structure chart, steel wire 8 is connected on lid thickening layer 7 by slip-off preventing hold-down screw 9 and lid 3.
As shown in Figure 1 and Figure 2, cover frame 4, pressing plate 2 select structural steel to process.Sealing ring 5 adopts silastic material to make.Lid 3 material selection glass/epoxy composite material, lid 3 does not come off, and position adopts Kevlar fiber reinforcement and steel wire 8, screw 9 is fixed, and lid 3 adopts temperature in molding shaping.Cover frame 4, pressing plate 2 adopt polysulfide sealant to seal with the contact surface of lid 3.
