Description
?
Technical field
The present invention relates to a kind of woven composite thermal insulation layer and preparation method thereof, belong to the woven composite technical field.
Background technology
Along with going deep into of the extensive use of composite and people practice and theoretical research, for the development of woven composite provides the foundation at aspects such as raw material, combination process, interface theory, complex effects.Woven composite is that fibre bundle is woven into required preform constructions spare according to certain order and rule, carries out the dipping and the curing of matrix material with it as strengthening skeleton then.Braided material improvement has structurally increased substantially material property, and the braiding system of globality makes material not have the interlayer problem, and outstanding anti-vertical resolution is arranged, and the opposing cracking is superior to flaggy formula composite with tired performance.Woven composite also has good damping performance and ablation resistance breakage resistant luer performance except high ratio modulus with composite, high specific strength, high-fracture toughness, characteristics such as shock-resistant.The heat conductivility of different woven composites is different, and made woven composite insulating layer structure also can be different.Referring to list of references " composite fibre furnace lining and have the annular furnace of this furnace lining " (Xie Lin, Dong Lijun. the Beijing JingCheng Fenghuang Industry stove Engineering Technology Co., Ltd).Though that this composite fibre furnace lining has is not fragile, maintenance cost is low, structure processing, be shaped and assemble advantages such as simple, its effect of heat insulation is bad.
Summary of the invention
The object of the invention is to propose a kind of woven composite thermal insulation layer and preparation method thereof, with solving the bad shortcoming of composite heat shield structural heat-insulation effect.
A kind of woven composite thermal insulation layer is worked out by fibre bundle, it is characterized in that: above-mentioned fibre bundle has hollow structure, and is sealed with inert gas with segmented mode in the hollow structure; Above-mentioned fibre bundle is removed the material part behind the hollow structure, and its wall thickness is non-homogeneous form, and main load-carrying surface wall thickness is bigger than inferior load-carrying surface wall thickness.
The preparation method of above-mentioned woven composite thermal insulation layer is characterized in that comprising following process: (1), utilize fusible material as core, and preparation has the fibre bundle of hollow structure; (2), in the fibre bundle hollow structure, charge into inert gas and segmented seal; (3), utilize above-mentioned fibre bundle to carry out the braiding of insulating layer structure; Wherein revolving structure or hyperbolic structure utilize fiber cross section to work out for the fibre bundle of circle; Curved-surface structure that curvature is less or planar structure, utilizing fiber cross section is that square fibre bundle is worked out; Prism structure, utilizing fiber cross section is that non-square polygonal fibre bundle is worked out.
The inert gas of sealing though fibre strength reduces a little, reaches better effect of heat insulation in the above-mentioned hollow structure.The composite rod member of the hollow that the present invention adopts has in light weightly, and temperature tolerance is good, and thermal conductivity is low, and thermal insulation is good, and delamination resistance can be good, advantages such as the good and breakage resistant luer of anti-ablation performance of damping performance.

The specific embodiment
To understand in order technical characterictic of the present invention, result of use being had more clearly, it to be described.
The composite rod member of the hollow that the present invention adopts; Have advantages such as in light weight, that temperature tolerance good, thermal conductivity is low, thermal insulation is good; Also having the woven composite delamination resistance can be good, and the good and breakage resistant luer of anti-ablation performance of damping performance has been widened the Application Areas of woven composite greatly.In addition, can also be woven to different decorative patterns, the woven composite insulating layer structure is designed according to concrete environment, concrete requirement.
According to concrete operating position, the cross sectional shape of the composite rod member of hollow can be square (Fig. 3), annular multiple shapes such as (Fig. 4), and the rod member wall thickness can be adjusted as required.In the fibre bundle of hollow, inert gas can be filled, better function of heat insulation can be played.In the braiding process, can form different decorative patterns according to concrete requirement braiding; Angle during braiding not only can be a quadrature; Also can be oblique, and can also increase the thickness of woven composite insulating layer structure in position, reach the required mechanics requirement of some specific positions.
The specific embodiment one: step 1: fibre bundle processed to have certain flexible cross section be square hollow rods;
Step 2: the hollow fiber bundle rod member is woven on the required heat insulation member, with n root (n≤10) hollow rods side by side quadrature braiding form decorative pattern (Fig. 1);
Step 3: heating is solidified not completely crued composite fully;
Step 4: the woven composite insulating layer structure is repaired, satisfied instructions for use.
The specific embodiment two: different with the specific embodiment one is: step 1: fibre bundle is processed to have certain flexible cross section be the annular hollow rod member.
The specific embodiment three: different with the specific embodiment two is: step 2: the fibre bundle hollow rods is woven on the required heat insulation member, with n root (n≤10) hollow rods side by side the oblique braiding form decorative pattern (Fig. 2).
