By external for shaping equipment loom 41, the most woven carbon fiber one-way fabric 33 runs past equipped with asphalt mixtures modified by epoxy resin liposoluble
The bottom of the sprinkler 42 of liquid, is sprinkled upon carbon fiber one-way fabric 33 surface uniformly by sprinkler by resin solution.By drying
The temperature such as 80 DEG C that case 43 provides, vapors away the solvent in solution, makes thin resin layer 32 paste at fabric face.Through heating
Thin resin layer is the most uniformly fixed on carbon fiber one-way fabric 33 surface by temperature such as 40 DEG C and pressure 250N that roller 44 provides.
Then kraft paper let off roll 45 releases kraft paper 31, and kraft paper 31 on carbon fiber one-way fabric 33 covers, through chill roll 46
Cooling and shaping, finally by wind-up roll 47 rolling.Speed of production is 3m/min.
After testing, embodiment two gained pattern bonded fabrics surface viscosity is big, by the isolation of kraft paper 31, and will not between fabric
Mutually bonding, convenient use.In fabric, the collimation deviation of fiber is 1%.Paving pattern bonded fabrics during flat plate mold,
Directly fabric can be coated with at die surface.Through checking without obvious hole after using the solidification of RTM technique, mechanical property reaches to want
Ask.
The novel pattern bonded fabrics production technology of embodiment one, two, key point is to have abandoned traditional setting process to fiber
Carry out pretreatment or shuffling sizing fiber way, novelty be cladded with thin resin layer 33, tried hard to keep by the bonding between resin
The glacing flatness of card fabric fibre.During production, first according to the pattern bonded fabrics structure of design select to add thin resin layer 33 quantity and
Mode, then adds thin resin layer 33 by fabric face, reheats pressurized treatments, finally obtains the pattern bonded fabrics of needs.Simultaneously
