Structural Applications

In many structural applications, such as marine, aircraft and so on, structures are designed to withstand high impact loading, because they may be subjected to impact of the projectiles with high velocity [1,2] . Fabrics become good choice to resist impact of ballistic [3] because of light weight and high specific strength .

Laminated Composite Materials

Bend and shear tests were used to characterize the improvement in impact behavior of various ultrahigh carbon steel laminated composites. These tests turned out to deliver much more useful information about the mechanical properties of the laminates than the Charpy impact tests and were especially interesting for characterization of laminates of very high toughness values. The toughness of the various laminates was controlled by the rolling conditions that determined the quality of the bond and the appearance of delamination by the interfaces. The bend test allows determination of yield and maximum stresses, absorbed energy and permits graphical visualization of layer fracture and delaminations as testing proceeds. The shear test allows mechanical characterization of the bond quality between layers, permitting prediction of possible delaminations, and therefore, the mechanical properties of the layered material.

Comprehensive Characterization

High value manufacturing requires production-integrated, fast, multi-sensor and multi-scale inspection. To meet this need, the robotic deployment of sensors within the factory environment is becoming increasingly popular. For microscale measurement applications, robot-mountable versions of high-resolution instruments, that are traditionally deployed in a laboratory environment, are now becoming available. However, standard methodologies for the evaluation of these instruments, particularly when mounted to a robot, have yet to be fully defined, and therefore, there is limited independent evaluation data to describe the potential performance of these systems. In this paper, a detailed evaluation approach is presented for light-weight robot mountable scanning interferometric sensors. Traditional evaluation approaches are considered and extended to account for robotic sensor deployment within industrial environments. The applicability and value of proposed evaluation is demonstrated through the comprehensive characterization of a Heliotis H6 interferometric sensors. The results indicate the performance of the sensor, in comparison to a traditional laboratory-based system, and demonstrate the limits of the sensor capability. Based-on the evaluation an effective strategy for robotic deployment of the sensor is demonstrated.
