What are Reinforcement fibers?

Reinforcement fibers can be natural or synthetic, and they are used because they have better mechanical properties than wood. They don't exist only to provide speed, but to manipulate many properties of a blade such as the weight, sweetspot, flexibility, hardness and feeling.

They are usually fabrics, with various types of weaving patterns and densities, which are often as important as the fibers being used. Normally we refer to these fabrics in terms of their density and weave pattern, not thickness, as thickness will be a consequence of these factors. These fabrics alone don't have any real advantages, to be used to the full extent of their properties they must be infused with a resin. There are many types of resin and lamination methods, and every manufacturer has their own "recipe". So keep in mind that, even if the fabric being used is similar, results may vary from brand to brand.

There are many types of fibers, but in terms of fabrics you basically have two families: plain fabrics, which contain only one fiber, and hybrid fabrics which contain two or more fibers.

Plain Fabrics:

Glass-Fiber (GF)

The most subtle reinforcement fiber, it doesn't provide a big sweetspot or speed increase . It's useful if you wish to maintain a woody feeling, but with more dampened vibrations.

Basalt-Fiber (BF)

Performance wise it is similar to typical Carbon fiber, however it feels slightly softer so it's more suitable for a spin based game.

Diolen-Fiber (DF)

Diolen is a high tenacity polyester fiber, it has a really soft feeling and provides some vibration damping along with a small increase in sweetspot. Speed increase is minimal compared to other fibers.

Soft Carbon (sCF)

This is a non-woven type of carbon, very thin and light, also known as carbon fleece. Performance wise it's a very subtle reinforcement, with a small increase in the stability and speed of the blade, along with some vibration dampening.

Carbon-Fiber (CF)

The classic reinforcement fiber. Provides the biggest speed increase but compromises the feeling of the blade due to the increase in hardness.

Super Carbon-Fiber (S-CF)

The same as Carbon-fiber but in a heavier and denser weave pattern so the results are more pronounced.

Spread tow-Carbon (TC)

Spread tow is a special 'spreading' technology to make the individual tows of carbon fiber very flat and wide, producing thinner reinforcements . I used to call this one Textreme carbon, but spread tow carbon is the concept, Textreme is just a brand. Technically I'm not using Textreme, but another brand of spread tow carbon, hence the change. This is a good option for those seeking the typical carbon fiber feel, but still retaining the wooden characteristics of the blade. Currently I work with three versions of this fiber: 90 g/m2, 160 g/m2 and 200 g/m2.

Aramid-Fiber (AF)

This is a soft and elastic fiber that provides a good feeling, suitable for spin and control play.

Spectra (SF)

Spectra is a Ultra-High Molecular Weight Polyethylene fiber. This remarkably durable material is one of the world’s strongest and lightest fibers. Performance wise, this fiber feels soft, with a moderate speed and sweet spot increase, but it's main characteristics are the lightness and the loud sound it produces on hard impact.

Hybrid Fabrics:

Hybrid fabrics have more than one fiber type in their constitution, normally it's carbon weaved with another fiber in order to maximize the potential of both fibers.

Aramid-Carbon (AC-#)

Aramid weaved with carbon in a plain pattern. Not to be confused with ALC, altough similar, aramid and arylate are not the same. This fabric contains both aramid and carbon in both directions so it's balanced in terms of characteristics. The performance is similar to ALC, but the feeling is slightly harder.

Aramid-Carbon (AC-I)

Aramid weaved with carbon in a I pattern. It's similar to AC#, but the ratio of fibers is 2:1. This means that in the horizontal direction there is more aramid then carbon, and the opposite for the longitudinal direction. In terms of performance, this translates to more stiffness but with a softer feeling than AC#.

Aramid x-Carbon (AxC)

This fabric only has aramid in the horizontal direction and carbon in the vertical direction. This results in even more stiffness and softness than AC-I.

Aramid y-Carbon (AyC)

This is the opposite concept of AxC, here we have aramid in the vertical direction and carbon in the horizontal direction. The result is more flexibility combined with a harder feeling compared.

Super Aramid-Carbon (S-AC)

The same as AC but in a heavier and denser weave pattern so the results are more pronounced. This fabric has twill weave pattern, but that doesn't affect performance.

Super Aramid x-Carbon (S-AxC)

The same as AxC but in a heavier and denser weave pattern so the results are more pronounced. This fabric has twill weave pattern, but that doesn't affect performance.

Super Aramid y-Carbon (S-AyC)

The same as AxC but in a heavier and denser weave pattern so the results are more pronounced. This fabric has twill weave pattern, but that doesn't affect performance.

Innegra-Carbon (IC)

Innegra is very light fiber that has very good impact resistance. Combined with carbon in a I pattern, it provides a very good spin/control relation with an increase in speed and sweetspot. The feeling is soft and elastic, and very natural.


ALC is the most used fiber nowadays, and although the weave pattern of this fabric isn't exactly like what the big "B" is using, the results are very similar. It provides a relatively soft but crisp feeling, a good sweetspot and vibration dampening. One of the main characteristic of this fabric it's also its elasticity, the harder you hit the more you feel it "catching" the ball, which translates into more security compared to other fibers.

Zylon-Carbon (ZC)

Zylon is one of the toughest fibers on earth, it is very resilient and very hard to use. The weave pattern is the same as AxC, so it shares the same concept of higher stiffness with a soft touch, but with even more catapult and a lighter weight.

Super Zylon-Carbon (S-ZC)

This fabric has a higher density than ZC and a different weave pattern. It provides a little more flexibility, sweetspot and catapult, with a slightly crisper feeling.
