UV Light Exposure Causes Composite Material to Grow Stronger On Demand

Facebook X LinkedIn Email
ABERDEEN PROVING GROUND, Md., April 24, 2018 — A technique has been developed that causes a composite material to become stiffer and stronger when exposed to UV light. The technique can be controlled, allowing the strength of the material to be adapted to the requirements of the application. To develop the technique, engineers attached UV-light-reactive molecules to reinforcing agents (in experiments, carbon nanotubes were used). The reinforcing agents were then embedded in a polymer. Researchers found that when the polymer was exposed to UV light, interaction between the reinforcing agents and the polymer increased, causing the...Read full article

    nano
    An SI prefix meaning one billionth (10-9). Nano can also be used to indicate the study of atoms, molecules and other structures and particles on the nanometer scale. Nano-optics (also referred to as nanophotonics), for example, is the study of how light and light-matter interactions behave on the nanometer scale. See nanophotonics.
    additive manufacturing
    Additive manufacturing (AM), also known as 3D printing, is a manufacturing process that involves creating three-dimensional objects by adding material layer by layer. This is in contrast to traditional manufacturing methods, which often involve subtracting or forming materials to achieve the desired shape. In additive manufacturing, a digital model of the object is created using computer-aided design (CAD) software, and this digital model is then sliced into thin cross-sectional layers. The...
