Abstract
The present invention provides a kind of suction of composite molding zero glue thermocouple setting method, comprising the following steps: 1) confirms that thermocouple welding head is intact and is wound with temperature pressure sensitive band, solder joint is encased by temperature pressure sensitive band completely；2) it is placed on designated position in thermocouple, and lower placement fuse material on it, makes solvable sheet clamping of the thermocouple by upper and lower level；5) laying stripping, the upper surface and left and right of the soluble material above thermocouple are not contacted with stripping；6) it in the position away from soluble material certain distance, is placed below conducting wire with putty item and 7) pastes one layer of degumming mould cloth in thermocouple wire and air slot intersection.By fixing soluble material up and down in thermocouple, at high temperature, the gap between conducting wire and hot-press tooling is filled up, glue is avoided to flow out by fully wrapped around thermocouple wire after soluble material dissolution.Putty item can be used as second defence line, further ensure that glue will not flow out, and guarantee vacuum degree.
Description
Technical field
The present invention relates to composites processing technology fields, and specifically a kind of composite molding zero inhales glue thermocouple
Setting method.
Background technique
Carbon fibre composite is as a kind of advanced composite material, with light-weight, modulus is high, specific strength is big, heat is swollen
Swollen coefficient is low, high temperature resistant, impact resistance, it is corrosion-resistant, absorbing is good the advantages that, it is existing wide in fields such as aerospace, automobile, military affairs
General application.
Carbon fiber embryo material completes multi-compartment bed poststack, needs to carry out hot press operation by hot-press arrangement, it is ensured that between each layer
It is completely embedded.Hot press operation needs to carry out vacuum sealing to Carbon fibe embryo material.But after thermocouple is installed, thermocouple and hot pressing
There are gaps for tooling, and glue is caused to flow to vacuum bag along thermocouple wire, lead to broken bag, scrap of the product.
Summary of the invention
Present invention solves the technical problem that being that composite molding is that glue industry is easily flowed out along thermocouple wire in the prior art
The problem of.
The present invention solves the above problems by the following technical programs:
A kind of suction of composite molding zero glue thermocouple setting method, comprising the following steps:
1) confirmation thermocouple welding head is intact and is wound with temperature pressure sensitive band, and solder joint is completely by temperature pressure sensitive band packet
Firmly；
2) one piece of soluble material is first placed in the designated position of thermocouple；
3) middle position prevents thermocouple and contacts piece surface above the soluble material placed；
4) another piece of soluble material is placed above thermocouple, and is fixed with temperature pressure sensitive band, keeps thermocouple upper and lower
The soluble material clamping of layer；
5) laying stripping, the upper surface and left and right of the soluble material above thermocouple are not contacted with stripping, and can
The edge of delamination is fixed with temperature pressure sensitive band, guarantees that no stripping exposes；
6) it in the position away from soluble material certain distance, is placed below conducting wire with putty item, and with temperature pressure sensitive band
It is fixed；
7) one layer of degumming mould cloth is pasted in thermocouple wire and air slot intersection, and with temperature pressure sensitive band by degumming mould cloth
It is fixed.
Preferably, the soluble material is rubber material.
Preferably, in step 5), soluble material or so is away from stripping at least 10mm.
Preferably, in step 6), the putty item is away from soluble material at least 30mm.
Preferably, in step 6), the putty length is 3mm.
Advantages of the present invention are as follows:
By fixing soluble material up and down in thermocouple, at high temperature, fully wrapped around heat after soluble material dissolution
Gap between conducting wire and hot-press tooling is filled up, glue is avoided to flow out by galvanic couple conducting wire.Putty item can be used as second defence line,
Further ensure that glue will not flow out, guarantees vacuum degree.
Specific embodiment
The effect of to make to structure feature of the invention and being reached, has a better understanding and awareness, to preferable
Embodiment detailed description, is described as follows:
A kind of suction of composite molding zero glue thermocouple setting method, comprising the following steps:
Step 1. confirms that thermocouple welding head is intact and is wound with temperature pressure sensitive band, and solder joint is completely by temperature pressure sensitive band
It encases；
Step 2. first places one piece of soluble material in the designated position of thermocouple；
Step 3. middle position above the soluble material placed prevents thermocouple and contacts piece surface；
Step 4. places another piece of soluble material above thermocouple, and is fixed with temperature pressure sensitive band, makes thermocouple quilt
The soluble material of upper and lower level clamps；The soluble material is rubber material.
Step 5. laying stripping, the upper surface and left and right of the soluble material above thermocouple are not contacted with stripping, and
The edge of stripping is fixed with temperature pressure sensitive band, guarantees that no stripping exposes；Soluble material or so away from stripping at least
