The purpose of this utility model is to provide a kind of carbon fibre composite subway chassis, light-weight, rigidity is big, cost
It is low, have excellent performance, it is big to solve weight existing in the prior art, poor corrosion resistance, and service life is short, of high cost, electromagnetic shielding
The problems such as performance is undesirable.
The technical solution of the utility model is：
A kind of carbon fibre composite subway chassis, this kind of carbon fibre composite subway chassis use cell foams interlayer
Structure, this kind of carbon fibre composite subway chassis include the upper covering from top to bottom set gradually, laminboard layer and lower covering, folder
Sandwich layer is spliced using the spool of walking of cell foams and advance comprising, and several transverse bars are adhered on upper covering.
Further, upper covering is all made of fire-retardant carbon fibre fabric prepreg with lower covering and is made.
Further, upper covering is all made of the outer cure process of autoclave with lower covering and is made.
Further, it walks spool and uses VARI technological formings, and cabling pipe surface is coated with one layer of metal mesh.
Further, transverse bar is carbon fibre composite foam sandwich construction, and transverse bar includes the outer of foam and cladding foam
Covering, exterior skin are made of fire-retardant carbon fibre fabric prepreg.
The utility model has the beneficial effects that：
One, this kind of carbon fibre composite subway chassis, cell foams sandwich not only reduce manufacturing cost, and
And sound insulation, heat-proof quality are excellent, impact resistance and shock resistance resilience ability enhancing, it is often more important that effective to mitigate weight
Amount, reaches light-weighted purpose.
Two, compared with prior art, the utility model is integrally formed using inexpensive composite material process planning, is used
OOA techniques are integrally formed, and greatly reduce the manufacturing cost of carbon fibre composite subway chassis.
Three, the utility model is bonded using cell foams sandwich global formation and in upper covering with foam core knot
