Unidirectional Carbon Fiber Prepreg - 220gsm - T400 - carbon - fiber - 150g

Product Properties

150g carbon fiber unidirectional prepreg has the following characteristics:

- High strength and high stiffness: Carbon fiber itself has high strength, and the unidirectional arrangement enables it to fully exert its mechanical properties in the fiber direction. Its strength and stiffness are much higher than ordinary materials, and it can meet the application scenarios with high requirements for structural strength and stability.

- Low density: Light weight, with a specific gravity of about one-fourth of steel. When used in aerospace, automotive and other fields, it can reduce the weight of the structure, improve transportation efficiency and energy utilization, and does not affect the overall performance.

- Good corrosion resistance: It has excellent corrosion resistance such as acid and alkali resistance and oxidation resistance. It can be used for a long time in harsh environments, extend the service life of the product, and reduce maintenance costs. It is suitable for outdoor construction, chemical equipment and other fields.

- Strong designability: It can be processed into various shapes of components according to different mold shapes, which can meet the design requirements of complex shapes and structures, such as manufacturing special-shaped aerospace parts, automotive parts, etc.

- Good dimensional stability: When environmental factors such as temperature and humidity change, its dimensional changes little, which can ensure the accuracy and stability of the product during use. It is suitable for fields with high dimensional accuracy requirements, such as precision instrument manufacturing, etc.

Building reinforcement field

It can be used to reinforce and repair concrete structures and wooden structures, such as bridges, beams, columns and other structures of buildings, to improve the bearing capacity, seismic performance and durability of the structure, and extend the service life of the building.

Medical equipment field

It can be used to manufacture parts of medical equipment, such as CT scanning frames, operating bed boards, etc., using its good mechanical properties and radiotransmittance to ensure the strength and stability of the equipment while meeting the special needs of medical examination and treatment.

The construction of carbon fiber unidirectional prepreg mainly includes the following steps:

Construction preparation

- Material and tool preparation: Prepare carbon fiber unidirectional prepreg, release agent, cutting tools (such as scissors or special knives), scrapers, vacuum bags and sealing strips, vacuum pumps, etc. Ensure that the material quantity is sufficient and the tools are intact.

- Mold preparation: The mold should be clean and smooth, free of oil, dust and other impurities. Apply a release agent on the mold surface to facilitate demolding after subsequent prepreg molding. The application should be uniform to avoid local demolding difficulties.

Prepreg cutting

- According to the design requirements and mold size, use a cutting tool to cut the carbon fiber unidirectional prepreg into a suitable shape and size. Pay attention to the neat edges during cutting, and try to avoid fiber breakage or burrs, as this may affect the mechanical properties of the final product.

Laying prepreg

- Carefully lay the cut prepreg on the mold surface according to the designed ply direction and sequence. Unidirectional prepreg has a clear fiber direction, and it is necessary to ensure that this direction is consistent with the force direction required by the product design. During the laying process, use a scraper or other tool to gently squeeze the prepreg to expel air so that the prepreg fits tightly to the mold surface to avoid wrinkles or bubbles.

Vacuum packaging

- After laying the prepreg, use a vacuum bag to package the mold and prepreg. Cover the prepreg with a vacuum bag and seal the edges with a sealing strip to ensure that the vacuum bag is airtight. Then use a vacuum pump to extract the air in the vacuum bag to form a vacuum environment. This helps to further remove the air in the prepreg, so that the prepreg fits the mold more closely during the curing process, and is also conducive to the uniform distribution of the resin.

Curing treatment

- According to the curing characteristics of the resin in the prepreg, place the encapsulated mold in a suitable curing equipment (such as an autoclave or oven) for curing. During the curing process, parameters such as temperature, time and pressure must be strictly controlled. For example, the temperature usually needs to be raised, kept constant and lowered according to the curing curve provided by the resin supplier, and the time must also be accurately controlled to ensure that the resin is fully cured and the carbon fiber prepreg forms a stable structure.

Demolding and post-processing

- After the curing is completed, wait for the mold to cool to the appropriate temperature and demold the molded carbon fiber product from the mold. After demolding, some post-processing may be required for the product, such as trimming the edges, polishing the surface, etc., to obtain a final product that meets the requirements.
