Step 3: by the end pairing for sticking high-performance fiber of the left and right mold of I-beam mold for forming, in apposition position
Upper and lower end parts carry out R angle fillings, i.e., be twisted into using high-performance fiber and fill and lead up the upper and lower side R angles of apposition position with fiber type item,
Then high-performance fiber, shape are integrally coated with above the high-performance fiber of the flange formation on left and right mold respectively upper and lower surface
Flange above and below into the I-beam；
Step 4: by each left and right mold with intermediate auxiliary mould to the curve form of synthesis wing cover；
Step 5: by the I-beam mold for forming after pairing be placed on by step 1 lay the covering of high-performance fiber into
In type mold, and the clamping positioning mechanism for adjusting both sides is compressed；
Step 6: a layer thickness is laid in the upper surface of the placement I-beam mold for forming of step 5 as 5-10mm silicon rubber,
Formpiston is covered, molding is put into baking oven after tightening, is cured by cure profile；
Step 7: being demoulded after the completion of curing, composite wing integral panel is obtained.
7. the forming method of unmanned plane composite material integral panel according to claim 6, it is characterised in that：The high property
Energy fiber is any one or a few in carbon fiber, glass fibers, aramid fiber.
