The curing reaction kinetic parameters of CF832/T700 ultra-thin carbon fiber prepreg/epoxy resin systems were studied through DSC tests. The influence laws of pre-absorbing process parameters and curing process parameters on the mechanical properties of ultra-thin carbon fiber composite laminates were investigated by orthogonal tests. The most suitable adhesive film was determined by using three different adhesive films of EA9696NW

LWF–2B and FM73M to co-cure the ultra-thin prepreg laminates and Nomex honeycomb. The results show that the curing reaction activation energy of CF832/T700 prepregs is 85.98kJ/mol

the curing reaction is a slow first-order reaction. The pre-curing temperature
