SiClx is melted manufactured fiber, and dielectric constant and tangent loss are smaller compared with other class glass fibres, moreover, quartz is fine
The mechanical performance of dimension also can satisfy the production requirement of radar protective cover according to the difference of manufacturing process technology；In addition, quartz is fine
The linear expansion coefficient of dimension is smaller and there is elasticity modulus to increase and increased characteristic with temperature, to can guarantee the radar protective cover
With good dielectric properties.
Supplementary explanation, the performance of silicone resin formed with it is closely related, i.e., the ratio of organic group and silicon atom and
Methyl and the ratio of phenyl etc., silicone resin are usually to be protected by there is the organic silicon monomer hydrolytie polycondensation of trifunctional to form in radar
In the use process of shield, with the continuous raising of temperature, the organic group of silicon atom side chain constantly carbonizes at high temperature, generates
Free carbon is unfavorable for penetrating for electromagnetic wave, so that the wave transparent performance of composite material is influenced, and methyl silicone resin is relative to benzene
Carbon-coating not easily generated under high temperature for base organic siliconresin, therefore can be used as the matrix of good electromagnetic wave transparent material.
The radar protective cover 2 is in coniform, and 2 outer surface of radar protective cover is airflow design, fairshaped design,
So that the radar protective cover 2 is able to bear certain aerodynamic loading, to reduce damage of the aerodynamic loading to the radome wall surface.
The thickness of the radar protective cover 2 is between 5-8mm, and 2 maximum gauge of radar protective cover is in its tip, minimum thickness
Degree is because the radar protective cover 2 is when encountering extraneous barrier, tip often first touches barrier, institute in its root
It is maximum with damage of the barrier to its tip, therefore, it is necessary to guarantee that the pressure that 2 tip of radar protective cover can bear is maximum,
To reduce a possibility that radar protective cover 2 is damaged due to strikes obstacles, prolong backward with 2 tip of radar protective cover
During stretching, thickness is gradually reduced, and root reaches minimum, to be effectively reduced the weight of the radar protective cover 2, radar is protected
The thickness of shield 2 is thinner, and the sending electromagnetic wave of radar ontology 1 is shorter through the stroke of 2 cover wall of radar protective cover, absorbed energy
Amount is also fewer, thus power transmission coefficient will be bigger, but the thickness of cover wall unconfined cannot be thinned, and first have to consider it
Whether intensity, rigidity meet the requirements, it is also contemplated that meeting the requirement of reflection, keep optimum thickness.

Heat treatment temperature process optimization is carried out to it in muffle furnace, and the temperature being heat-treated is between 800-1200 DEG C, due to resin
The elevated temperature strength of sill is usually lower, makes using being limited, therefore that its can be improved in cracking process is close by dipping-repeatedly
Degree still, after multiple high temp is handled, and will affect reinforcement intensity to improve the elevated temperature strength of material to unfavorable
It is analyzed so needing to select suitable heat treatment temperature by series of experiment research in improving the strength of materials, the results showed that,
After 800-1200 DEG C of high-temperature heat treatment, dielectric constant when wave frequency is 9.30GHz is less than 3.5, and material
Wave transmission rate is up to 90% or more, can satisfy the requirement on electric performance of the radome.
