US Navy Resin Will Make Composites Stronger, Flame-Resistant & Cheaper to Process
A new high-performance, PEEK-like phthalonitrile resin developed by the US Naval Research Laboratory is resistant to high temperatures, flammability, and impacts, and can be processed using standard methods like resin infusion molding and resin transfer molding. Loss tangent characteristics and excellent dielectric permittivity make it especially useful in applications where RF transparency is required, such as high-temperature radomes that shield radar antennae like the one on the top of this E-2C Hawkeye aircraft.

The Navy's new powerful LaWS laser weapon is great at taking out composite targets over a mile away. How much time before other countries like China and Russia design their own and burn through our composites?
Ann, while I don't have a use for this information today, it is certainly handy to have. This source of knowledge is a resource, and like most resources becomes reallyn valuable wnen you need it, and only "interesting" the rest of the time. I can see an immediate application of this material in high frequency hiher power RF electrical applications.
What was not mentioned about the new material was outgassing, which affects the usefulness of a material for satellite and space applications, and also for semiconductor fabrication applications.
ON the issue of technical writing, DN has consistently evidenced that the deeper a technical issue is, the lesser the comments. (Case in point; this article). But I think that should be expected; -- for example, there have been several other deep articles from Guest Bloggers that I couldn't begin to comment on. The interested field of commenters just naturally narrows.
ON the subject of RIM, I was [minimally] familiar with another industrial process – Reaction Injection Molding (a different RIM) which is [loosely translated as] an injection of a 2-part epoxy. A very slow processing time because 'cure' is required. Checking my old faithful resource, Wikipedia doesn't have a page for your definition of RIM but does link it to your other suggested process, Resin Transfer (RTM).
Always interesting to learn about new things – Thanks!
The new composites manufacturing innovation center is intended to be a source of grand challenges for industry, like the kind that got us to the moon under JFK. These aren't the words its new CEO Craig Blue used, but that's the idea and the vision behind the Institute for Advanced Composites Manufacturing Innovation (IACMI).
The 100% solar-powered airplane Solar Impulse 2 is prepping for its upcoming flight, becoming the first plane to fly around the world without using fuel. It's able to do so because of above-average performance by all of the technologies that go into it, especially materials.
As the 3D printing and overall additive manufacturing ecosystem grows, standards and guidelines from standards bodies and government organizations are increasing. Multiple players with multiple needs are also driving the role of 3DP and AM as enabling technologies for distributed manufacturing.
A growing though not-so-obvious role for 3D printing, 4D printing, and overall additive manufacturing is their use in fabricating new materials and enabling new or improved manufacturing and assembly processes. Individual engineers, OEMs, university labs, and others are reinventing the technology to suit their own needs.
For vehicles to meet the 2025 Corporate Average Fuel Economy (CAFE) standards, three things must happen: customers must look beyond the data sheet and engage materials supplier earlier, and new integrated multi-materials are needed to make step-change improvements.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
