Abstract
An assembly includes an elongated, cylindrical pipe; a plumbing connector attached to an end of the pipe, in which an opening is defined through a length of the plumbing connector; and a negative Poisson's ratio (NPR) coating disposed on an interior surface of the plumbing connector that defines the opening, in which the NPR coating on the plumbing connector is configured to exhibit an auxetic behavior in response to application of a force to the NPR coating, in which the end of the pipe is disposed concentrically within the opening of the plumbing connector such that the NPR coating of the plumbing connector contacts an outer surface of the pipe, and in which a portion of the plumbing connector extends beyond the end of the pipe.
Claims12
An assembly comprising:
- a plumbing connector, in which an opening is defined through a length of the plumbing connector;
- and
- a negative Poisson's ratio (NPR) coating disposed on an interior surface of the plumbing connector that defines the opening, in which the NPR coating on the plumbing connector is configured to exhibit an auxetic behavior in response to application of a force to the NPR coating, in which the NPR coating comprises a layer of an NPR material and a layer of a material having a positive Poisson's ratio,
- in which when the plumbing connector is attached to an end of a pipe, the end of the pipe is disposed concentrically within the opening of the plumbing connector such that the NPR coating of the plumbing connector contacts an outer surface of the pipe, and in which a portion of the plumbing connector extends beyond the end of the pipe.
