specific Embodiment approach 1
[0024] Embodiment 1: A method for preparing a thermoplastic resin matrix carbon fiber-titanium / titanium alloy laminate in this embodiment includes the following steps:
[0025] 1) Using a film lamination method or a powder impregnation method to impregnate a carbon fiber unidirectional fabric or a carbon fiber woven fabric with a thermoplastic resin to prepare a carbon fiber reinforced thermoplastic resin prepreg;
[0026] 2) The surface of the titanium / titanium alloy with a thickness of 0.3-0.5 mm is subjected to combined treatment of sandblasting and silane coupling agent or combined treatment of alkaline anodization and ultraviolet light grafting;
[0027] 3) Brush the release agent evenly on the inner side of the mold, lay up the titanium / titanium alloy and carbon fiber reinforced thermoplastic resin prepreg obtained by surface treatment in the mold according to the laying rules, and lay the titanium / titanium alloy and prepreg on each layer Place a thermoplastic resin film...
specific Embodiment approach 2
[0029] Specific embodiment two: the difference between this embodiment and specific embodiment one is: the process of preparing carbon fiber reinforced thermoplastic resin prepreg by film lamination method in step 1) is: single-layer carbon fiber unidirectional cloth or carbon fiber woven cloth with a thickness of 0.05-0.1mm thermoplastic resin film is superimposed, under the condition of temperature 250-370℃ and pressure 0.5-5MPa, it is hot-pressed by vulcanizer, and the rubber content is 50-60% and the thickness is 0.1-0.2mm. Prepreg. Others are the same as in the first embodiment.
specific Embodiment approach 3
[0030]Specific embodiment three: the difference between this embodiment and specific embodiment one is: the process of preparing carbon fiber reinforced thermoplastic resin prepreg by powder impregnation method in step 1) is: single-layer carbon fiber unidirectional cloth or carbon fiber woven cloth is dispersed The roller enters the electrostatic chamber in which thermoplastic resin powder with a particle size of 5-15 μm is suspended, and is fully mixed. According to the standard of prepreg glue content of 50-60% and thickness of 0.1-0.2mm, the single-layer carbon fiber unidirectional cloth or The carbon fiber woven cloth is supplemented with resin powder from top to bottom and placed in a vulcanizer. Under the conditions of temperature of 250-370°C and pressure of 0.5-5MPa, it is hot-pressed to obtain a prepreg. Others are the same as in the first embodiment.
