Description
Technical field
The present invention relates to Material Field, particularly to composite and the laying method of a kind of anti-staking tear.
Background technology
Composite board member uses self-plugging rivet to typically require the expansion at self-plugging rivet when connecting two-layer or multi-layer sheet
End installs metallic gasket additional, to protect the composite panel aperture of self-plugging rivet expanding end not to be torn.
One assembly is made up of big L/D ratio carbon fiber square tube and metal U-shaped part, and two components need to use the mode of riveting
Link together, owing to carbon fiber square tube is the closure member of big L/D ratio, it is impossible to use pressure-riveting process to connect molding, can only adopt
Using staking technique, the i.e. molding of self-plugging rivet riveting, carrying out this assembly technology in open space is more ripe skill
Art, however narrow and small or close space, due to cannot or inconvenience install metallic gasket, this assembly technology just can not use or
Efficiency is the lowest.
According to the riveting requirement of traditional carbon fiber board, need to install additional metallic gasket at carbon fiber back, but due to behaviour
Make narrow space, use special fixture to stick with glue in advance in rivet hole position and connect the method for metallic gasket and install additional, due to bonding gold
The quantity belonging to pad is a lot, and workload is very big, and production efficiency is low, and owing to blindmate is installed, after curing of the glue, the most easily goes out
Drop phenomenon, manufacturing schedule and quality of existing metallic gasket is severely impacted.
Summary of the invention
In order to when solving blindmate installation in prior art, metallic gasket drops phenomenon, manufacturing schedule and quality by serious shadow
The problem rung, the invention provides composite and the laying method of a kind of anti-staking tear.
The present invention provides the composite that a kind of anti-staking tears, be followed successively by from down to up one or more layers fabric with
And multilamellar unidirectional fiber prepregs, the longitudinal of described every layer of fabric and the machine direction of unidirectional fiber prepregs are with pre-
If horizontal plane becomes different angles to lay.
Present invention also offers the laying method of the composite of a kind of anti-staking tear, comprise the following steps:
Determine one or more layers fabric prepreg and multilamellar unidirectional fiber prepregs respectively lays the number of plies and side
To, wherein, the longitudinal of described every layer of fabric becomes not with preset level face with the machine direction of unidirectional fiber prepregs
Same angle；
According to the described number of plies and direction, one or more layers fabric prepreg and multilamellar unidirectional fiber prepregs are existed
Lay on mould, and be compacted.
The present invention has the beneficial effect that:
In the composite that the present invention provides, every layer of fabric and unidirectional fiber prepregs fabric are respectively provided with respective side
To, solve in prior art owing to when blindmate is installed, metallic gasket drops the manufacturing schedule caused and quality is severely impacted
Problem, it is possible to need not install sheet metal additional, directly use self-plugging rivet to connect two-layer or multi-layer sheet (composite panel/composite wood
Flitch, or composite panel/metallic plate), will not produce simultaneously tear due to the expansion of self-plugging rivet composite aperture, from
And cause bonding strength reduction, even Joint failure.
