Nanotek got into a gray area of being a true single wall, because of the launchpad, but it's all metal. Here is the best explanation from Mr. Anderson himself.
-----------------------------------------------------------------------------------------------------------------------------------------------------------------
The NanoTek has been called an “All Metal Composite.” But what does that mean?
The confusion lies in the common usage of the term composite. It is generally related to the resin-over-fiber composite manufacturing technique used in building the current composite bat products. However, the question is more easily answered when you look to the actual definition of the word composite.
A composite is a mixture of different components or a structural material that gains its strength from a combination of complementary materials. A brick made from dirt and straw is a composite structure.
The NanoTek is not a composite bat. The NanoTek is a proprietary high strength, elastic alloy molecularly and permanently bonded to a precisely-engineered-aluminum alloy shell to form a single, all-metal, wall. It is only composite in the sense that more than one metal is used.
What is the LaunchPad design?
The NanoTek is not a two piece bat. The Nanotek Launchpad is an entirely metal design feature that creates a highly reactive hitting area while putting the weight directly behind the ball and strategically placing counteractive weight to optimize MOI.
The design is the result of a decade-old concept that was only made possible with the new material advancements. The Launchpad is a layer of super-hard, super-elastic material that is molecularly bonded at the atomic level over the entire effective hitting area. Because the Launchpad is harder and stronger it isolates the vibrational response to the work area of the barrel from the underlying aluminum substrate shell. What that means is that, because of the isolation, the underlying shell does not retain the residual vibrational energy from the ball-bat impact that normally travels up and down the length of the bat and is lost in a typical single-piece-bat design, nor is the energy absorbed in the connection as it is in a two-piece-bat design. The energy is captured in the Launchpad section of the NanoTek bat and because the Launchpad has higher elasticity it allows a more efficient transfer of the energy to the flight of the ball. Because of the barrel isolation with unlike materials the effective hitting area is larger than other single wall bats by more than double.
If the NanoTek is not a composite bat and the launch pad is layers of bonded metals, the question becomes, “Is NanoTek a multiwall bat?”
The NanoTek is not a multiwall bat. The whole object to the design of a multiwall bat is that the walls can move independently like the leaf springs on a car. The idea is to increase the flexibility of the system by allowing the individual components flex independently and maintaining durability by the overall thickness of the combined walls.
The NanoTek’s performance comes from the thin, single, barrel wall which is made possible by the LaunchPad.
