Stick Technolgy

Stick Bends

  • The Pro Bend incorporates a near maximum 23.5mm bend positioned just below the mid-point of the shaft. The shaft has then been shaped to give a thinner profile under the right hand and a balance point that favors the head end of the stick. This gives a combination of great stick turn-over because of the shape but better hitting power because of the balance point and sweet spot.
  • The Ultimate Bend is the most aggressive low bend that we have ever made, the maximum bend at the lowest legal point enhances drag flicking and aerial skills, it has a shaft weighting to aid stick head speed but still provide power and balance for the slapping and pushing associated with elite level skill execution.
  • The DSH bend is a 2mm concave face specifically designed to work with a 24mm bend to enhance drag-flicking and 3D skills. The 'cup' aids ball pull back from the left side of the body and enhanced elimination skills. The new DSH mold has a fatter shaft profile to increase the cross sectional area and aid hitting power,
  • The Standard Bend incorporates a 22mm bend positioned at the mid-point of the shaft; the balance point has been moved up the stick (towards the handle) to enhance the playing characteristics of these sticks. (Higher balance point, less head weight, easier ‘turn-over’ and therefore ball movement.

Weight Reduction

Composite material advances have resulted in enhanced strength in Mercian products. The use of aeronautical grade Carbon Fiber from British, continental European and Asian facilities means that the weight of our light sticks has been reduced with no compromise on hitting power, torsional strength or durability.

Fiberglass

The basic material used in hockey sticks is Fiberglass. Fiberglass is a strong lightweight material and is used for many products including sports equipment such as hockey sticks. Although it is not as strong and stiff as composites based on Carbon Fiber, it is less brittle, and its raw materials are much cheaper. Its bulk strength and weight are also better than many metals, and it can be more readily molded into complex shapes once impregnated with complex resins. This flexibility means that as a skeleton, a Fiberglass base resists some of the energy that can compromise the pure brittle nature of Carbon Fiber. It is why we (Mercian) believe that a 100% carbon stick is not the perfect performance solution.

Carbon Fiber

Anywhere where high performance is required Carbon Fiber's superior strength to weight ratio offers significant advantages, and sporting goods are no exception. It is used to replace or reduce metal, wood and steel content in a wide variety of sports applications. Carbon strands are made up of multiple filaments. 1K means 1000 filaments per strand. The greater the number of fibers the heavier the material. 1K Carbon is found in the electronics industry and used in military grade equipment. 3K and 6K are found in different types of sporting goods. 12K is usually considered too heavy for use in hockey sticks, further specifications exist but are increasingly heavy and not used in sports goods. Mercian uses Carbon from UK and European plants as well as the highly regarded Toray Carbon from Japan, the importation of such materials into Pakistan rather than using local materials increases the manufacturing cost but this is more than outweighed by the increase in the quality of the finished product.

Summary: Stiffness, durability, power, and very high strength to weight ratio allowing for a high performance light-weight hockey stick.

Aramid / Kevlar

Other materials such as aramid (Kevlar is a trademark of DuPont) can replace glass fiber and Carbon and enhance performance characteristics within a composite stick. It has superb impact absorption and durability so is perfect for using on high impact points such as stick edges and faces.

Summary: Light weight and has excellent anti abrasion and impact properties and is used on the heal of the hockey stick to prevent quick wear down from use. Aramide fibers in the shaft also enhance vibration dampening and enhance edge protection for backhand skill execution.

Basalt

Basalt fiber is a material made from extremely fine fibers of basalt, which is composed of the minerals plagioclase, pyroxene, and olivine. It is similar to carbon fiber and fiberglass, having better physicomechanical properties than fiberglass, but being significantly cheaper than carbon fiber.

Resins

Prior to hand-crafting and then ‘baking’ under heat and pressure, the raw materials are impregnated using complex resins. Standard commercial resins will form adequate bonds between the layers but for true high-quality performance multiple resins are blended to ensure the chemical properties of all the materials are considered and accounted for in the manufacturing process.

Lay-Up and Production Cycle

The quality of the raw materials is only one factor with respect to final product quality, resins also dictate the final product quality. However the nature of the lay-up – how the materials are placed on top of each other is just as important. The Mercian factory ensures that fibers are placed within layers at angles maximizing the performance characteristics of the materials and they are not too tightly layered to ensure that the resin impregnates all the fibers completely and the layers can bond totally. The pressure and temperature within the molds is also tightly regulated to ensure an optimum production cycle.

High-Friction Finish

The Pro Line sticks feature a silicon based resin coating on the face of the sticks. Increased friction on the head of a stick, as seen on many of the leading brands products, enhances ball control and skill execution. On the Proline we have created that friction surface using silicon rather than silica. These tiny (black) rubber particles give a texture to the surface and whilst they also have the characteristics of rubber they can squash and at a microscopic level provide a degree of ‘damping’ and assist with stopping and ball control. The 100 series and 200 series create the same friction based coating but using silica, These transparent particles allow for the creation of a high friction surface but allowing the graphics on the heads of the sticks to remain visible to the end user.

Nano-Carbon Technology

Think small and strong. All composite sticks are made using a complex process of bonding materials together; the smaller the gaps between the materials in these bonds, the stronger the stick will be. Nano-Carbon Technology involves adding microscopic carbon straws to the bonding resins for the purpose of filling these tiny gaps which are otherwise filled only by resin. These hollow carbon straws within the resin provide multi-directional strength between the materials, with the result being a stronger and more resistant bond which increases the overall strength of the stick. Nano-Carbon Technology is used in all sticks with a carbon content.

Piezo-Electric Fibres (VRZ)

Piezo-electric fibers in the VRZ ‘Vibration Reduction Zone’ on the Pro Line sticks are used to ‘harvest’ the vibrations created in these super-stiff sticks and turn them into heat. The result of this is efficient vibration dampening. The materials themselves have been known about since 1880; The Piezoelectric Effect is the ability of certain materials to generate an electric charge in response to applied mechanical stress. When piezoelectric material is placed under mechanical stress, a shifting of the positive and negative charge centers in the material takes place, which then results in an external electrical field. As a vibration damping material, the vibrations created from striking a ball create the ‘stress’ within the Piezo fibers and create an electrical charge (dispersed as heat).

Quad Carbon Sleeve

Mercian’s example of a ‘braided’ stick is using a pre-woven carbon sleeve, braiding the carbon fibers at source, using high specification resins to create a fully enclosed carbon sleeve. Four layers on sleeve are used across the complete surface and a specific
pressure points to create the optimum strength shell.
