1.Product Description
By carbon fiber yarn, epoxy resin, release paper and other materials, through coating, hot pressing, cooling, laminating, winding and other processes of composite materials called carbon fiber prepreg, also known as carbon fiber prepreg cloth.
The reason why it is called prepreg cloth is because it is only the initial immersion of resin and carbon fiber, and the final immersion is the reason when the product is formed.
The main products include:
unidirectional carbon fiber prepreg cloth (24T, 30T, 36T, 40T), the weight can be from 30g/m² to 250g/m², the resin content uniformity is controlled within 0.5%.

3.Product Features
1. High strength and rigidity
Carbon fiber prepreg has high tensile strength and rigidity, much higher strength than traditional metal materials, and the weight is very light, which can effectively reduce the weight of the structure and improve the efficiency of the structure.
2. Corrosion resistance
Carbon fiber prepreg has good corrosion resistance, can effectively resist acid, alkali, salt and other chemical substances erosion, extend the service life.
3. Insulation
Carbon fiber prepreg has good insulation properties, can effectively prevent electric shock and electromagnetic interference, suitable for electronics, communications and other fields.
4. Thermal stability and high temperature resistance
Carbon fiber prepreg can still maintain its mechanical properties and dimensional stability at high temperature, and can be used for a long time in high temperature environment.
5. Excellent processing performance
Carbon fiber prepreg can be cut, spliced, bonded and other processing operations according to the design requirements, which is convenient to manufacture complex structural parts.

---------- FAQ ----------
1.How Much Resin Will I Need To Wet Out Carbon Cloth Fabrics?
For wet-lay lamination you will use approximately the same weight of resin as the weight of the fabric. For example, with a 200gsm cloth, for 1 square metre you will have 200g of fabric and thus will need 200g of resin to wet it out, plus a small amount of wastage for the brush and mixing pot.
2.What Does The '3k' Mean?
'3k' is the filament count or tow size. It simply means that each 'bunch' of carbon fibers that this cloth is woven from is made up of 3000 individual carbon filaments. Bigger counts (6k, 12k etc.) means chunkier 'bunches' of carbon so chunkier fabrics.
3.What Typical Thickness Would Each Layer Be?
Thickness of any reinforcement is dependent on consoldation(how much it's 'squashed down'. For this reason we generally give out thickness figures for when the reiforcement is consoldated under vacuum (1bar); this seems like the most useful figure. For example,a 90gsm carbon,a single layer, compressed under vacuum, would be about 0.1mm thick. For a 200gsm carbon a single layer would be about 0.25mm thick. This is the number you see listed under 'thickness' in the specification table.
4.How Do I Go About Ordering A Sample Of This Carbon Fabric?
You can purchase a sample of our fabrics here.
5.How Much Resin Would Be Needed On Average Per Sqm?
Well, this depends entirely on what reinforcement you're laminating, speficically how thick and heavy it is. If you're laminating 5mm of carbon fiber you'll use a lot more resin that if you're laminating just 1mm of it. Fortunately though there a really quick rule to get a good estimate-simply add up the total weight of your reinforcement and you'll probably need the same weight in resin. This means that if you're laminating 5 layers of 200g carbon(so a total of 1000g of carbon) then you'll want about 1000g(i. e.1kg) of Epoxy Resin.If it was 2 layers of 450g glass then you'd need about 900g per square metre.
6. What Is The Maximum Service Temperature As I Want To Make An Engine Rocker Cover.
The carbon fabric itself will survive many hundreds of degrees and is not the limiting factor for almost all applications. The limiting factor will be the heat distortion temperature of the resin system you plan to laminate this fabric with.
An engine rocker/cam cover may easily be exposed to hot oils at around 120°C as well as heat from the exhaust which would be dependent on the engine configuration and level of tune. As such we would recommend considering using a higher temperature resin system.
7. Does The Carbon Have A Shelf Life?
For very critical applications, such as aerospace, even dry carbon fabrics will be 'lifed' due to very gradual degradation of the sizing on the fibers, however in practice, for most applications, the degradation is minimal and most users would consider dry fabric s to not have a shelf life when stored appropriately.
8.What Colour Is Carbon fiber?
All Carbon fibers are naturally charcoal black in colour.
