WE USE ONLY THE HIGHEST QUALITY MATERIALS

We work closely with our boutique carbon and fibreglass suppliers to obtain the optimum fibre types and resin systems to ensure all CTS blanks are at the leading edge in terms of material development.

100% CARBON CONSTRUCTION

What makes our blanks some of the best is our use of 100% uni-directional carbon fibre. We combine this with our carbon helical core (made also from 100% uni-directional carbon fibre) to obtain superior hoop strength. Hoop strength stops the blank from creasing like a drinking straw and it keeps the blank from ‘ovaling’ under pressure (softening and potentially failing).

 

One common alternative to our carbon helical is a uni-directional carbon with a layer of scrim. Some companies use a carbon scrim or tissue, but most use a glass scrim. A scrim is a quick and effective way to get hoop strength, but, because it is generally resin rich to fill the voids, puckering of the main carbon uni laminate can occur, causing fibre twists.

 

Grass scrim is also a woven material, which makes it up to 40% weaker than a non-woven material. This strength decrease is due to the strands being bent as they weave across the opposing strands.

INTERNAL HIGH STRENGTH FERRULE

A high strength ferrule is placed at each join, to provide superior crush and split resistance. Even our Quartz S Glass series have their own internal ferrule. There is no need for the rod builder to place a ferrule wrap at this point for reinforcement.

 

In this heavier wall (base) section of our Affinity DQ, you can see a number of layers of reinforcing along with the helical on the inside. The number of wraps and the grade of material for the wraps is varied depending on the loads it will be subject to.

MULTI CARBON CONSTRUCTION

Our designs incorporate up to five different types of carbon in each blank. Each carbon type is placed at various parts of the blank to optimise strength and weight. We’ve worked with our boutique carbon suppliers to continuously maintain the most cutting edge carbon/matrix systems.

 

CTS uses three main carbon systems:

 

    1. CTS HM. We’re very careful not to ‘over cook’ our modulus. We’ve selected what we believe to be the highest modulus fibre available that still maintains acceptable strength properties. While there are higher modulus fibres available to us, we believe the ‘in the field’ strength decreases outweigh their benefits. Typically our CTS HM Carbon system combines a selection of intermediate and high modulus fibres, to create super lightweight, responsive designs.
    2. CTS IM. A stunning all-round material that combines great stiffness with awesome strength. This system is primarily used where a slightly more robust blank is required, yet still requires the response and agility of our HM system. CTS IM uses an industry leading, low resin system. This improves the stiffness to weight ratio close to our CTS HM system.
    3. CTS HS. Our super high strength carbon system. It’s softer than both our HM and IM systems, but it more than makes up for this in its ability to flex and carry some seriously big loads. We use this primarily for designs that are not so weight critical and will undergo some fairly hefty loads. Its larger elastic region creates blanks with a wider working range.
    4. CTS USG. We’ve worked long and hard to create the clearest, lightest Uni Directional S Glass system. Outstanding strength, beautiful clarity and the best stiffness to weight ratio of any glass based system available.

GEN III DESIGN SYSTEM

The popular heavy duty GT Fight Series utilises our Generation III design system, incorporating three material layers:

      1. A 1K box weave in an unsanded finish. This layer ties together and supports the core uni-directional fibres and adds a robust outer layer capable of taking knocks and abrasion.
      2. The middle / core section of the laminate is the powerhouse for the blank. This is made from pure uni-directional carbon. We vary the grades of this material from 33msi through to our 57msi materials depending on the area of the blank and what we want this part of the blank to achieve.
      3. A lightweight carbon helical for hoop strength and to improve compression strength. The carbon helical core varies in weight from tip through to the butt. We’re careful not to add any unnecessary weight.
