Abstract

The invention discloses a protective coating composite material for a jet cutter for an emergent opening of a passenger plane service door in the air, which has two constitutive modes: mode one, a carbon fiber cloth layer, a natural rubber layer and a Kevlar cloth layer are arranged from the inside to the outside and are adhered and compounded together through epoxy resin; and mode two, the carbon fiber cloth layer, the Kevlar cloth layer and a polyurethane layer are arranged from the inside to the outside and are adhered and compounded through the epoxy resin. Through the compounding of fiber and rubber, the protective coating composite material can effectively block the transmission of explosion waves, reduce noises, reduce the dead weight of a protection device without generating injurious broken pieces. The protective coating is attached to the surface of a shell of the jet cutter, can limit the explosion secondary effect in the minimum zone, and adapts to the narrow space in a plane cabin.

Description

Jet cutter overcoat composite during the aerial emergency opening of passenger plane service cabin door
Technical field
The overcoat composite of jet cutter when the present invention relates to the aerial emergency opening of a kind of passenger plane service cabin door.
Background technology
According to the 15 article of (four) regulation of CCAR-21R2 " civil aviation product and parts qualified authorization regulation " " except that aerodone or manned balloon; the applicant has all taked enough measures in the time of should proving each flight test, so that the group membership that takes a flight test can emergency escape and use parachute; ".For guaranteeing aircraft group membership's the safety of taking a flight test in the process of taking a flight test, need also assembling " ARJ21-700 aircraft aerial main cabin emergency pressure relief and service door open system " in the aircraft of taking a flight test of development.
This system adopts accurate blasting technique, the emergency pressure relief in the realization high-speed flight passenger plane cabin and the quick unlatching of service cabin door.Need to adopt line style cumulative cutting technique forming the pressure release hole on the nacelle rear covering, cutting off hinge and snap close on the service cabin door, remove of the constraint of fuselage doorframe, so that the quick unlatching of service cabin door to service cabin door.Because the space is narrow and small relatively in the passenger plane cabin, the group of taking a flight test personnel are apart from the minimum distance of blast cut point only about 1.5m, therefore, must effectively protect the shock wave of jet cutter generation, noise, metal flying etc.
Summary of the invention
Goal of the invention: the objective of the invention is characteristics at jet cutter in the prior art, a kind of safe, reliable, efficient contact integrated protection layer composite is provided, and this overcoat composite also is applicable to the security protection of implementing the cutting of line style amplitude transformer under other like environment.
Technical scheme: in order to realize the foregoing invention purpose, the technical solution used in the present invention is:
According to the characteristic of jet cutter blast time effect and solid dielectric understanding to this time effect attenuation law, for realizing the integrated protection of blast time effects such as shock wave, noise, for to prevent that overcoat from producing the metal fragmentation that disperses again, overcoat is made of nonmetallic materials simultaneously.In order to bring into play the mutual supplement with each other's advantages effect of nonmetallic materials, protection coating materials adopts the natural or synthetic rubber of high-strength resistant to elevated temperatures carbon cloth, elasticity excellence, the inorganic and organic non-metal materials such as Kafra fiber cloth of high-strength and high-ductility, and is that binding agent is composited with epoxy resin.
Carbon cloth, Kafra fiber cloth have different thickness characteristics, and natural have different material behaviors with synthetic rubber, therefore, according to structure that is cut object and features of shape, have made two kinds of overcoat composites of category-A and category-B respectively.
Category-A overcoat composite is made of trilaminate material, is followed successively by carbon fibre cloth layer, caoutchouc layer, Kafra fiber layer of cloth, each interlayer from inside to outside and is coated with epoxy resin, forms a composite bed of being made up of four kinds of materials.Wherein the thickness of carbon fibre cloth layer is 2.0 ± 0.1mm, lay by two its warps of carbon cloth intersections at 45, with improve overcoat each to stress performance; The natural rubber layer thickness is 2.0mm; The thickness of Kafra fiber layer of cloth is 1.5 ± 0.1mm, and also the fiber cloth by 45 ° of two warps intersections constitutes.Epoxy resin all has good adhesive property to three kinds of materials, can make composite have good shaping and solidifiability, has strengthened between fiber cloth warp and the parallel interconnecting simultaneously, helps bringing into play the holistic resistant behavior of fabric.
The blast of cutter not only produces shock wave, and produces high-temperature gas, so high-strength resistant to elevated temperatures carbon cloth is arranged on innermost layer; Natural rubber has different wave impedance with carbon cloth, thereby helps concussion and the decay of shock wave in two layers of material; And Kafra fiber cloth has remedied natural rubber obdurability deficiency, simultaneously also because the difference of both wave impedance helps concussion and the decay of shock wave in two layers of material.Epoxy resin also has certain effect to reducing noise except that the bond strength that improves above-mentioned three kinds of materials.
According to what of cutter explosive payload, the category-A overcoat can use by individual layer, but also multiple layer combination is used.
Category-B overcoat composite is made of trilaminate material, is followed successively by carbon fibre cloth layer, Kafra fiber layer of cloth, polyurethane rubber layer, each interlayer from inside to outside and is coated with epoxy resin, forms a composite bed of being made up of four kinds of materials.Wherein, the thickness of carbon fibre cloth layer, Kafra fiber layer of cloth and formation are all with the category-A material, and the thickness of layer of polyurethane is then determined according to the architectural feature that is cut object.
When installing and fixed space is seriously limited, need to be made into when installing and fixing body employing category-B composite with polyurethane.
Preferred 6101 epoxy resin of above-mentioned epoxy resin.
Above-mentioned category-A and category-B overcoat composite all are fitted in the case surface of jet cutter.
Beneficial effect: the overcoat composite has made full use of the characteristics of fiber high-strength light, helps reducing the deadweight of protector, little, the good looking appearance of body; Compare with adopting the metal protection material, can not form the fragmentation of hurting sb.'s feelings; Utilize the compound of fiber and rubber, can effectively block the blast impulse wave propagation, reduce noise.The case surface that the overcoat composite is fitted in jet cutter helps blast time effect limits effectively having adapted to the narrow and small characteristics in space in the cabin in minimum zone.
