A low-cost, plastic-based textile from Stanford University engineers could cool the body efficiently when woven into clothing.

In a University of Maryland study, researchers at the A. James Clark School of Engineering have demonstrated that windows made of transparent wood provide more consistent natural lighting and better energy efficiency than glass.

Advanced composite materials processable by cost-effective manufacturing play an important role in developing lightweight structures for future space and planetary exploration missions. With the growing demand for improved performance in the...

By combining biology and 3D printing, Lawrence Livermore National Laboratory (LLNL) scientists have created a reactor that continuously produces methanol from methane at room temperature and pressure.

A new class of phenolic and carbon-fiber-reinforced phenolic composites has been developed for thermal protection systems. The new materials have the advantage of being lightweight, strong, and tough, yet heat resistant and flexible. They retain excellent mechanical strength at high...

A series of lightweight (density below 2.0 gm/cm3) composites has been manufactured that have controllable properties. The core composite has been improved to provide higher strength (similar to aluminum), extremely low density, receptivity to exterior coatings, and highly designable...

The dispersion of a layered silicate into an epoxy matrix often increases the material strength and stiffness, but reduces resin toughness. This innovation is a method to selectively place organically modified clay within specific regions of an epoxy blend, where the clay...

As the power density of advanced engines increases, the need for new materials that are capable of high operating temperatures, such as ceramic matrix composites (CMCs), is critical for turbine hot-section static and rotating components. Such advanced materials can...

Developers from Harvard’s School of Engineering and Applied Sciences and the Wyss Institute for Biologically Inspired Engineering have produced the first untethered soft robot — a quadruped that can stand up and walk away from its designers. The researchers were able to scale up earlier soft-robot...

Like other manufactured products that use sandwich panel construction to achieve a combination of light weight and strength, turbine blades contain carefully arrayed strips of balsa wood from Ecuador, which provides 95 percent of the world’s supply.As turbine makers...

Researchers with the U.S. Department of Energy (DOE)'s Lawrence Berkeley National Laboratory (Berkeley Lab) have devised a technique whereby self-assembling nanoparticle arrays can form a highly ordered thin film over macroscopic distances in one minute.

An Iowa State research team led by Reza Montazami is developing "transient materials" and "transient electronics" that can quickly and completely melt away when a trigger is activated. The development could mean that one day you might be able to send out a signal to destroy a lost credit card.To...

Soldiers facing rugged terrain and extreme temperatures are continually searching for ways to reduce the weight of their gear. In a search for solutions to this persistent issue, U.S. Army scientists and engineers have preliminarily demonstrated body armor that is 10 percent lighter through new...

In the future, Army aircraft may be made of all composite materials, and the Prototype Integration Facility Advanced Composites Laboratory is ready. Part of the Aviation and Missile Research Development and Engineering Center's (AMRDEC's) Engineering Directorate, the Prototype Integration...

Textile-based composites could significantly benefit from local toughening using nanofiber coatings. Nanofibers, thermoplastic or otherwise, can be applied to the surface of the fiber tow bundle, achieving toughening of the fiber tow contact surfaces, resulting in...

Producing strong, lightweight, and complex parts for car manufacturing and the aerospace industry is set to become cheaper and more accurate thanks to a new technique developed by engineers from the University of Exeter (UK). The research team has developed a new method...

Boeing (Everett, WA) has delivered the first 787 Dreamliner to Japan's All Nippon Airways (ANA). The 787 Dreamliner is an all-new airplane featuring a host of technologies that benefit both airlines and passengers. It is the first mid-size airplane capable of flying long-range routes, enabling...
