Aerospace Technology Used to Repair Bridges The Kentucky Transportation Center’s (KTC) research team, in cooperation with the Kentucky Transportation Cabinet and the Federal Highway Administration, recently determined that a product originally intended for aerospace technologies could be used to successfully repair damaged concrete bridges. Developed by A&P Technology, QISO Braided Triaxial Fabric is a single-layer quasi-isotropic carbon fabric that drastically improves damage tolerance and energy absorption and has been applied to jet engine fan cases, aircraft control surfaces, and radio dishes. Issam Harik, Manager of the KTC Structures Program at the University of Kentucky, decided to use QISO to restore the capacity of a bridge pier in Louisville, Ky. The steel reinforcement of the pier was severely rusted in the vertical and transverse directions. The concrete cover also had multiple pieces that had deteriorated and fallen off, which exposed the pier core. ‘‘A single layer of QISO Triaxial Fabric can be applied to the bridge pier in place of two orthogonal layers of fabric having unidirectional fibers.

This fabric has cut the application time in half, which reduces the repair costs,’’ said Harik. The KTC was the first to use QISO for civil engineering infrastructure purposes. To date, four bridges in Kentucky have been repaired using this technology.

Microscope Camera Produces Images Standalone or Connected to a Computer Leica Microsystems introduces Leica MC120 HD and MC170 HD digital microscope cameras. They produce high-quality, full-color still images and full-HD movie clip recordings for all microscope applications. The camera can be used standalone without a PC, in which case camera commands are made by a wireless remote control. Or it can be connected to a PC or Notebook and offers full compatibility with LAS and its many add-on LAS modules. The new high-performance cameras provide high-speed, precise images in real time at a rate of up to 30 frames per second. They are directly connectable to an HD monitor as a standalone solution or to a computer via USB interface. While the 2.5 megapixel Leica MC120 HD is suited for almost all microscope applications, the Leica MC170 HD with a resolution of 5 megapixels acquires the finest details at low magnifications. For fast documentation or hands-on training, the user can record full-HD movie clips as MP4. Images and movies are easily, cost-effectively stored with high quality onto a portable SD card.
