Full Field Nondestructive Techniques for Imaging Composite Fiber Volume Fraction

In a composite the matrix distributes the load onto and between the fibers. It is therefore important to know the volume fraction of fibers to ensure proper load distribution and predicted structural performance. The most common method of determining composite fiber volume fraction (FVF) involves removal of the matrix by burn off or acid digestion. While estimates of the fiber, matrix and void ...

Short fiber reinforced composite: the effect of fiber length and volume fraction.

AIM The aim of this study was to determine the effect of short fiber volume fraction and fiber length on some mechanical properties of short fiber-reinforced composite (FRC). METHODS AND MATERIALS Test specimens (2 x 2 x 25 mm3) and (9.5 x 5.5 x 3 mm3) were made from short random FRC and prepared with different fiber volumes (0%-22%) and fiber lengths (1-6 mm). Control specimens did not conta...

Simultaneous Reconstruction and Segmentation of CT Scans with Shadowed Data

We propose a variational approach for simultaneous reconstruction and multiclass segmentation of X-ray CT images, with limited field of view and missing data. We propose a simple energy minimisation approach, loosely based on a Bayesian rationale. The resulting non convex problem is solved by alternating reconstruction steps using an iterated relaxed proximal gradient, and a proximal approach f...

finite element simulation and experimental study on energy absorption of 3d woven glass fiber composite sandwich panels

abstract: in this paper, the results of experimental and numerical simulation of low velocity impact process have been carried out to investigate energy absorption of composite sandwich panels with 3d woven fabrics of glass fibers and epoxy resin. for this purpose, diagrams of force-displacement of the quasi-static and quasi-dynamic impact tests were studied. for the finite element simulation, ...

Position Prediction in CT Volume Scans

In their daily work, radiologists often need to localize and align parts of CT volume scans to perform among others di erential diagnosis. In these cases, it is desired to load only the relevant sub volume of the scan and to align the sub volume automatically to the correct position of the query scan. Common techniques employ landmark detectors and interpolation to solve this problem. Yet, thes...
