What is the difference between 2D carbon fiber composites and 2.5D carbon fiber composites? Let’s make a comparison between the two types.
When we talk about 2D and 2.5D, we generally refer to low-density carbon fiber composite materials, generally the density will not exceed 1.5g/cm3. This article no longer introduces high-density products and structures such as 3D carbon fiber composite, 4D carbon fiber composites.

2D refers to the carbon cloth laminated board: high flexural strength, easy to delaminate if the process is not good, the efficiency is faster than that of deposition, easy to make large size, generally used for material racks; carbon fiber content of 80%, uniform density, High strength and long service life.
2.5D refers to acupuncture preform pressed board: the strength is lower, but it is not easy to delaminate, the efficiency is faster than that of deposition, it is easy to make large size, and it is generally used for cover or guard plate; the carbon fiber content of acupuncture is only 30%, the density is uneven, the outer density is high, the inner density is low,
2.5D can also be made into high-density boards by CVI/CVD: deposition boards are generally not made in large sizes unless there are special requirements and special purposes. Its characteristics: higher comprehensive strength, long process time, not easy to make large size, easy to deform, generally used for structural stress parts. Among them, the aircraft brake disc is made of this structure and method, plus some other processes and formulas, and then the density of the finished product is about 1.8g/cm3
According to the above product characteristics and production process differences, you can choose the product type independently to meet your specific needs. In addition to the difference in process and cost, 2D and 2.5D carbon fiber composites are also slightly different in price, that is, 2D carbon fiber composites are more expensive than 2.5D carbon fiber composites under the same density and size. A little, about 10-20$/kgs higher.
Price and comparison of 2D and 2.5D carbon fiber composites:
2.5D carbon fiber composite prices:
density:1.2g/cm3, price: 90～120$/kgs.
density: 1.4g/cm3, price: 100～130$/kgs;
Ex.work basis, without machining and packaging costs!
For this kind of 2.5D carbon fiber composite, under normal circumstances, the density of 1.5 will not be achieved.
2D carbon fiber composite prices:
density: 1.2g/cm3, price: 100～130$/kgs.
density: 1.4g/cm3, price: 110～140$/kgs;
density: 1.4g/cm3, price: 120～150$/kgs;
Ex.work basis, without machining and packaging costs!
We will not describe the properties of 2D and 2.5D low-density carbon fiber composite materials in detail here, unless the density and strength of low-density sheets are required, as well as the flatness of processing.
Other Names of the carbon fiber composite material: CFC, Carbon composite, C/C, carbon fiber composite, carbon carbon composite, carbon reinforced carbon, carbon fiber reinforced carbon, carbon carbon.
