Various embodiments are directed to apparatuses and methods involving an elastomer material comprising a flexible polymer backbone with a particular ratio of at least first moieties and second moieties. The first moieties provide a first number of dynamic bonds resulting from interactions between the first moieties and the second moieties provide a second number of dynamic bonds resulting from interactions between the second moieties, the second number of dynamic bonds having a weaker bonding strength than the first number of dynamic bonds. The elastomer material, based on the ratio of the first moieties and second moieties, exhibits autonomous self-healing, a particular toughness, and is stretchable.

A tire repair machine has a base with a tire support, a clamp, and an injector. The clamp is releasably holds a tire for repair on the tire support. The injector is movable relative to the base and forces melted compound into a repair zone of the tire for repair. There is also provided a method of repairing a tire that utilizes a tire repair machine. A tire is clamped in the tire support of the base. The repair zone is drilled to clear the area to be repaired. A melted compound is injected into the repair zone of the tire. Once repaired, the tire is released from the clamp and tire support of the base.

A mould tool is disclosed, for use in repairing the eroded leading edge of a wind turbine blade. The mould tool comprises a flexible sheet and a framework which is flexible in one direction, for conforming to the curved edge of the blade, but rigid in the other direction. The mould tool may include tapered side walls. Preferably, a method or repair involves use of a mould tool with tapered side walls, and use of a similar mould tool which lacks the tapered side walls. To repair a section of the edge of a turbine blade, first stripes of resin are injected, spaced apart along the length of the section, using the mould with side walls. The gaps between the stripes are then filled using the mould without side walls.
