The molding characteristic of easy processing has important role to preparation SiCf/SiC composite material.
According to being consulted reference materials, deflector mostly uses special steel material as heat-resisting material at present, and deflector can block warship
The wake flame discharged when carrier aircraft is taken off, wake flame, which is guided into two sides and top, prevents deck of burning.In the behind of deflector, have more it is huge
Big copper pipe, a large amount of seawater circulate herein, to reduce the temperature of deflector itself.But in this way, on the one hand increasing
Whole warship weight, on the other hand reduces efficiency of taking off, and therefore, seeks a kind of anti-oxidant, high temperature resistant and exempts from water cooling deflector to increasing
Adding efficiency of taking off to improve carrier-borne aircraft survival ability and striking capabilities has the function of not replacing.
Summary of the invention
To meet the needs that carrier-borne aircraft quickly goes up to the air, the purpose of the present invention is intended to provide a kind of silicon carbide fibre enhancing carbonization
The preparation method of silicon based composite material utilizes carbofrax material low-density, wear-resistant, corrosion-resistant, low thermal conductivity, high temperature resistant etc.
Water cooling is exempted from feature, realization, shortens stand-by time of taking off.
In order to solve the above technical problem, the present invention provides a kind of preparation method for exempting from water cooling deflector, feature
It is, comprising the following steps:
(1) precast body is weaved: three generations's silicon carbide fibre is used, by two dimension weaving at silicon carbide layer laying up, with carbon after stacking

(5) it connects: screw thread process being carried out using diamond cutter, then will directly be carried out with ceramics bolt between different units
Connection, ceramic bolt is one of short fiber reinforced or long fiber reinforcement compound material bolt.
As prepared by the above method exempts from water cooling deflector, tensile strength 320MPa~360MPa, bending strength 520MPa
~560MPa, fracture toughness is in 20MPa.m1/2~25MPa.m1/2, 80 W/mK of thermal coefficient~85W/mK.
For the present invention from the point of view of deflector combination process, preferably using average molecular weight range is 350~500 higher molecular weight
Cyclosilane progress is 3 times compound, and cracking gained carborundum powder is micron order in this way, is conducive to be diffused to the inside of prefabricated component.
Beneficial effects of the present invention are simply described below:
(1) in composite material preparation process, using low molecular weight cyclosilane as deposition aid, compared with methylchlorosilane,
Acidic components content in tail gas is reduced, it is relatively friendly to environment；
(2) deflector prepared using the continuous carbofrax fibre toughening of low thermal conductivity, density is only former high temperature alloy
1/3~1/4, exempt from water cooling, high temperature resistant and cooling efficiency are 3~5 times of high temperature alloy, and material loss of weight is this means that identical matter
Amount, the warship body quantity that can carry arms increase；
(3) SiCf/ SiC ceramic matrix composite material thermal coefficient is low, once leaving fire source, material temperature is reduced rapidly, this is conducive to improve
Efficiency of taking off and carrier-borne aircraft survival ability.
