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.

Abstract

The invention discloses a preparing method of a thermoplastic resin matrix carbon fiber-titanium/titanium alloy laminate plate, and belongs to the field of light composite materials. The technical purpose is to solve the problem that currently the interface glue joint effect of titanium alloy of carbon fiber reinforcement titanium alloy laminate plate TiGr and a prepreg is poor. The thermoplastic resin comprises three kinds of high-performance thermoplastic resin including polyether-ether-ketone (PEEK), polyphenylene sulfide (PPS) and polyetherimid (PEI), with the coordination of a film laminating method and a powder impregnation method, the problem that the impregnation effect of the thermoplastic resin on carbon fiber is poor is solved.

Description

technical field [0001] The invention belongs to the field of lightweight composite materials, and in particular relates to a preparation method of a thermoplastic resin matrix carbon fiber-titanium / titanium alloy laminate. Background technique [0002] Fiber metal laminates (Fiber Metal Laminates, FMLs) is an interlayer hybrid composite material formed by laying metal sheets and fiber-reinforced resin prepregs alternately and then curing under a certain temperature and pressure. The unique composition of the FMLs material determines that it is different from both traditional metal materials and previous composite materials. Compared with single metal materials, it is light, fatigue-resistant, corrosion-resistant, and flame-retardant; Compared with resin composite materials, it has high damage tolerance, high notch strength, good impact resistance and heat and humidity resistance. At the same time, the fiber metal laminate has strong designability, and the layering method an...
