New Polymer Is Self-Healing and Has Shape Memory
New Polymer Is Self-Healing and Has Shape Memory
Researchers at Texas A&M University and the Army Research Laboratory have created a new self-healing polymer
Researchers with Texas A&M University and the Army Research Laboratory have created a new family of synthetic polymers that can be used in realistic prosthetics and soft robotics as well as many military applications. The new material is self-healing, recyclable, and has shape memory. It is also very useful for 3D printing, allowing complex, multilayered 3D-printed parts to be easily printed and then melted at high temperatures and reused as printing ink again.
The secret of the new polymer is dynamic and reversible crosslinking using small molecules of furan and maleimide embedded chemically in the prepolymer. Increasing the number of these molecules increases the stiffness of the material, up to 1,000 times. The chemical bonding of the furan and maleimide molecules can be reversed at high temperatures, softening the material. But at room temperatures, the molecules quickly reform the crosslinks allowing the polymer to stiffen and self-repair any tears. The material also allows different shapes to be programmed at different temperatures, meaning that when heat is applied to the material it will transform from one shape to another.

Hexcel and Safran Expand Contract for Aircraft Composite Materials
Hexcel and Safran Expand Contract for Aircraft Composite Materials
Hexcel and Safran expand their global long-term supply agreement
Hexcel and Safran have expanded their global long-term agreement to include supplies for Safran’s cabin, seats, and aerosystems programs in addition to the existing engine programs. Hexcel supplies high-performance, advanced composites, such as carbon fiber, as well as adhesives, prepregs, and dry fabrics for aircraft engines and interiors. Thierry Viguier, vice president of Safran Materials Purchasing, said, “Hexcel has shown again, during this difficult period of time, that they are a strong and reliable long-term partner.” The two companies have worked together for more than 35 years now and look forward to a long partnership serving the aerospace industry in the future.

Plastics Pipe Institute Celebrates 70th Year
Plastics Pipe Institute Celebrates 70th Year
Plastics Pipe Institute is celebrating its 70th year
The Plastics Pipe Institute (PPI), the major North American plastic pipe industry trade association, is celebrating 70 years. PPI was formed in 1950 as the Plastic Pipe Manufacturers Association when plastic pipe was still a fairly new invention. PPI President David Fink stated, “Since the very beginning, PPI has provided the vision and the leadership that has produced the establishment of uniform test and design criteria that became the foundation for all current applications of plastics piping.” After all the innovations of the last 70 years in plastic pipe, the next 70 years will see even more innovations in resins and applications along with a whole new membership in the PPI.
