Article with tunable flexibility using reversible cross-linking fluids

A hose assembly, comprising:

• a first hose length comprising a first wall with a continuous phase made of a first material, a first plurality of inclusions made of a second material, and one or more first energy conduits, wherein the first material has a first rigidity with a first variability, and the second material has a second rigidity with a second variability, the first variability depends on energy emitted from the one or more first energy conduits, and the second variability is substantially independent of energy emitted from the one or more first energy conduits;
• a second hose length comprising a second wall with a continuous phase made of the first material, a second plurality of inclusions made of the second material, and one or more second energy conduits;
• and
• a connector for joining the first hose length to the second hose length, the connector comprising a first portion coupled to the first hose length and a second portion coupled to the second hose length, the first portion having a plurality of peripheral passages parallel to an axis of the connector and aligned with the first plurality of inclusions and the one or more first energy conduits to receive the second plurality of inclusions and the one or more second energy conduits.
