1.Product Description
Aramid fiber prepreg cloth is a resin based aramid fiber reinforced composite material made of epoxy resin glue and aramid fiber (Kevlar) through hot melting, coating, hot pressing, cooling, laminating, winding and other processes.
It is composed of aramid fiber yarn, epoxy resin, release paper and other materials. Aramid fiber prepreg cloth is a semi-finished product containing epoxy resin and aramid fiber and uncured. After the product is heated and cured, it can be formed.

3.Product Features
Firstly, corrosion resistance, long life.
Secondly, high strength, low density. The strength of the prepreg can reach 6-12 times that of steel, and the density is only one-fourth of that of steel.
Thirdly, good plasticity. The prepreg can be made into any shape according to the mold shape, which is easy to form and easy to process.
4.Typical Uses
Aramong fabric prepreg is widely used in fishing tackle, sports equipment, sporting goods, aerospace and other fields, military used in the manufacture of rockets, missiles, satellites, radar, bulletproof vehicles, body armor and other important military products.
Restrictions
This product is not classed as dangerous goods for transport and can be shipped to all destinations without restriction.

---------- 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?

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.
