The mechanical performance of condensation material test specimen；The heating rate for controlling curing reaction temperature and device eliminates curing reaction releasing
Heat causes test specimen to generate thermal stress, ensure that reaction keeps the temperature constant state of certain time, and then improve the mechanics of test specimen
Performance；
3, carbon fibre initial rinse fabric is directly layered on forming metal plate in this method, is realized to carbon fibre composite mould
It is molded while can complete to be bonded；Adhesive property is effectively improved, adhesive strength is improved；Meanwhile forming process resin solidification
With bonding process cementing agent is cured is carried out at the same time, greatly save the time, improve production efficiency；
4, riveting is carried out to composite material and metal sheet bond before carbon fibre composite is fully cured in this method
It connects, does not directly have to transfer in the riveting of the same device；Resin is easy to be riveted still in viscoelastic state before being fully cured, and
The brittle break to composite material and cementing agent is effectively avoided, the stability and intensity of connection are directly enhanced；
5, riveting is carried out to composite material and metal sheet bond before carbon fibre composite is fully cured in this method
It connects, resin rivets in the state of still having certain fluidity, can empty connector air, effectively avoid connector since there are air
Caused by etching problem；Meanwhile as the composite material that riveting process is not fully cured deforms into rivet and metal sheet
Between trepanning semitubular rivet, dissimilar metal is avoided to corrode, improves the corrosion resistance and stability of connector connection, into
One step improves bonding strength；
6, use trepanning semitubular rivet, riveting process that semitubular rivet hollow parts air can be discharged in method,
Uncured resin flows into rivet trepanning and is closed, and so that rivet is bonded completely with carbon fibre composite, metal sheet, raising connects
Head intensity, avoids corroding.
