Muscle soft mode, panel soft mode vulcanize under vacuum conditions respectively.
In order to preferably realize the present invention, further, the blank of laying L shape part on reinforcing rib laying mould, and every paving
Folded 5 layers need encapsulated vacuum bag and apply vacuum preloading at normal temperatures and pressures, and vacuum degree reaches -0.090MPa or more, and precompressed
Time is more than or equal to 15min；Surplus is cut along the net sideline of reinforcing rib laying mould, removes to obtain L shape part.
The process technology scheme includes reinforcing rib soft mode manufacturing method, panel soft mode manufacturing method, laying method, group
Conjunction method and vacuum bag packaging method.Technical process includes manufacture panel soft mode, reinforcing rib positioning soft mode, laying, combines and determine
The processes such as position, package curing.The present invention be it is a kind of manufacture T shape Composite Material Stiffened Panel mould program and technology side
Case, applied to vacuum bag-autoclave molding technology of composite material, the invention is particularly suited to manufacture panel and reinforcing rib to differ
Long T shape Composite Material Stiffened Panel, is applicable to co-curing and total adhesive technology.Belong to composite material parts manufacturing technology
Field.
In view of the problems of the existing technology the present invention exactly, develops a kind of manufacture T shape Stiffened wall of design
The purpose is to solve reinforcing rib position in T shape Composite Material Stiffened Panel manufacturing status quo for the mould program and process technology scheme of plate
It sets low precision, straightness and shape is irregular, panel surface poor flatness, presence is layered/takes off in uneven thickness, component on the whole
Viscous/high problem of porosity.
It is adhesively fixed between panel locating piece and template using pressure sensitive adhesive tape in order to dismantle and clear up.Prepare its shaping mould,
2 layers of Airpad sheet rubber of paving and 2 ~ 3 layers of enhancing prepreg are sulfided into such as Fig. 9 and Figure 10 in autoclave after encapsulated vacuum bag
Type.Process conditions are as follows: temperature is 175 ~ 185 DEG C, 90 ~ 120min of time, 0.40 ~ 0.75MPa of pressure, and keeps complete in overall process
Vacuum.It is taken out from shaping mould after the completion of solidification/vulcanization, cutting removal surplus is ready to use in the technical process of manufacture product.
Prepare its shaping mould, locating piece and shaping mould are used into pin positioning and fastening, two layers of Airpad sheet rubber of paving and 2
~ 3 layers of enhancing prepreg notice that sheet rubber Airpad and increase enhancing prepreg must be bonded to each other with locating piece and be connected to one
It rises, it is inseparable.Sulfidization molding in autoclave after encapsulated vacuum bag, and process conditions are as follows: 175 ~ 185 DEG C of temperature, the time 90 ~
120min, 0.40 ~ 0.75MPa of pressure, and vacuum is kept in overall process.It takes out, cuts from shaping mould after the completion of solidification/vulcanization
Prescind the technical process that manufacture product is ready to use in except surplus.
Panel soft mode completes on composable mold and gets out composable mold first, installs strengthening rib strip locating support, and pacify
Install the reinforcing rib soft mode with location hole；Panel locating piece is placed under reinforcing rib soft mode, the two flushes, and uses double-faced pressure-sensitive
Adhesive tape is pasted onto panel locating piece in the template of composable mold.2 ~ 3 layers of Airpad sheet rubber of paving and 2 ~ 3 layers of increasing in template
Strong enhancing prepreg.Disassembly removal reinforcing rib locating support and reinforcing rib soft mode.Encapsulated vacuum bag is on composable mold, in hot pressing
Sulfidization molding in tank, and process conditions are as follows: 175 ~ 185 DEG C of temperature, 90 ~ 120min of time, 0.40 ~ 0.75MPa of pressure, and complete
Process keeps vacuum.It is taken out after the completion of solidification/vulcanization, is ready to use in the technical process of manufacture product.
By scheduled ply stacking-sequence, material, angle requirement laying panel at blank on composable mold, need to assist with certainly
The equipment such as dynamic blanking, laser projection execute laying work in Clean room.5 layers of every laying needs encapsulated vacuum bag normal in room temperature
Pressure applies vacuum preloading, and vacuum degree is required to reach -0.090MPa or more, and squeeze time reaches 15min or more.
Strong L shape part is superimposed into blank on reinforcing rib laying mould upper berth, and 5 layers of every laying is similarly required to need encapsulated vacuum
Bag applies vacuum preloading at normal temperatures and pressures, and vacuum degree is required to reach -0.090MPa or more, squeeze time reach 15min with
Upper presses the guidance of net side cutting groove, cuts surplus, blank is removed from laying mould, every two L shape part is in the form of " back-to-back "
It combines on panel that is at T-shaped and being mounted on composable mold, reinforcing rib soft mode is installed and its position is determined with reinforcing rib locating support
It sets, then panel soft mode is installed.The side of vacuum bag is encapsulated in the template of composable mold and within locating support, another side seal
On reinforcing rib locating support.
In hot pressing in-tank-solidification, successively following behaviour is removed from the molds product later: removal auxiliary material removes reinforcing rib
Locating support removes panel soft mode, removes the reinforcing rib soft mode with location hole, remove the reinforcing rib soft mode without location hole, take
Product out.
