Applications in General

Applications can choose between material, scale, and geometry.

Materials can be plastics such as PVC and PEM, aluminum, pultruded carbon composites, wood resin compounds, and steel.  Plastics can vary with their flexibility.

Scale can easily vary from 1  to 30 cm for the master profile length and height.

Geometry can vary with bendability, twistability, and slidability.

The geometry can produce rectiliniear bundles or circular bundles.

The cost of materials will vary by the quantity being used.  This is escpecially relevent when competing with wood.  It would take enormous amounts of PVC being extruded to be competitive with wood for basic structual use.  This is where curved structures and ease of assembly may give this technology the advantage.

Specific Applications:

-

Post and Beam houses where load bearing beams are curved.

-

Tree Houses that can be large look-out towers or view cabins.  Backyard tree houses for kids.

-

Tree structures to hold up large roofs e.g. malls, gyms, auditoriums.

-

Boat and Ship hulls.  The advantage being ease of making a hull shape plus redundant resistance to damage and ease of repair.

-

Aircraft structures such as fuselage parts and floors.  Carbon composites would give strength and low weight.

-

Toy building sets and whatever someone might dream up.

-

Leaf Springs, spring boards.  This is where the assembly is not locked so that individual extrusions slide.

-

Houses, decks, fences, pergolas.  Depends on how low the cost of materials can get.

-

Sky scrapers.  Some modern sky scrapers are being given a twisted architecture.  Even steel can be extruded.

-

Space Applications.  Building a space station would be difficult and expensive.  The difficulty could be eased by using slidable extrusions and glue (which works in space) for curved rotating sections.  More Here.
