notarboca, thanks for the explanation. We are discussing materials, here, not processes. I agree that the more it is used the greater the benefit. So far, all of these new materials are discovered and provided by commercial entities, so I'm not sure how they could be provided or distributed without without commercialization.

What I meant was if more manufacturers were using this, or a similar process, it would be of great benefit.  Commercialization is very good, too; you discover the process, you can license it and profit from it.

notarboca, can you tell us what you mean? This material and Axion's material use in the Scottish bridge are both proprietary processes developed by industry and commercialized. What alternative method were you thinking of?

Jack, this is not the same material I reported on for the bridge built in Scotland:

That one uses Axion's recycled-bottle-derived material.

Ann, I wish this was not a proprietary process; much good could come from everyone upcycling PBTs, with such an available resource

Great article.  Is this the same genearl process / material that was discussed in a previous piece relating to bridge construction?  It seems that there are more and more uses for this.  Maybe, some day soon there will be profit in recycling and municipalities can subsidized their budgets out of recycling rather than having to pay for mandated programs.

bobjengr, glad you enjoyed the article. The SABIC representatives I met with mentioned that their Innovative Plastics division originated in the former GE group. I was really impressed with what SABIC has accomplished. That said, SABIC is a Saudi Arabian company, not an American one, without all of the constraints (even for beneficient reasons) American ones have and with many social and political conditions US engineers might not want to live with.

There was no mention of this specific material used for Volvo's side air deflection brackets also being used for under-hood applications (I would have reported it, since I'm interested in that application, too). SABIC did not say if it is developing a version of this material, or other materials, for that use. In what I've seen in the market to date, handling hot and cold air and handling under-hood temps are apps with two different sets of specs.

Ann, that's for the clarification. So by end again it can be recycled for different component manufacturing.

Ann, the reason I asked the question is that I'm curious about underhood applications for automotive. Can it withstand underhood heat?

Artificially created metamaterials are already appearing in niche applications like electronics, communications, and defense, says a new report from Lux Research. How quickly they become mainstream depends on cost-effective manufacturing methods, which will include additive manufacturing.
SpaceX has 3D printed and successfully hot-fired a SuperDraco engine chamber made of Inconel, a high-performance superalloy, using direct metal laser sintering (DMLS). The company's first 3D-printed rocket engine part, a main oxidizer valve body for the Falcon 9 rocket, launched in January and is now qualified on all Falcon 9 flights.
A new thermoplastic composite for high-speed, high-volume injection molding has tensile strength that's close to, and sometimes better than, either lay-up composites or metals.
Lawrence Livermore National Laboratory and MIT have 3D-printed a new class of metamaterials that are both exceptionally light and have exceptional strength and stiffness. The new metamaterials maintain a nearly constant stiffness per unit of mass density, over three orders of magnitude.
Smart composites that let the material's structural health be monitored automatically and continuously are getting closer to reality. R&D partners in an EU-sponsored project have demonstrated what they say is the first complete, miniaturized, fiber-optic sensor system entirely embedded inside a fiber-reinforced composite.
