چکیده
In chopped carbon fiber tape reinforced thermoplastic?CTT?material, the anisotropic region of orientation after press molding often causes degradation mechanical properties and damage fracture. This study explores means obtaining shape tensors from molded products then predicting CTT fracture locations. Extensive data obtained by X-ray CT image processing are analyzed using a simple method to create waviness model.The tensor product is through phase imaging. The material finite element model with calculated mapped tensor, prediction simulated. Results showed that positions both test simulation agreed in specimens having large regions. However, small regions did not match. Therefore, images strain distribution piece under tensile load were compared cross-correlation. correlation between results, thus confirmed effectiveness simulation.

Fiber Orientation in Injection Molded Long Carbon Fiber Thermoplastic Composites
A set of edge-gated and center-gated plaques were injection molded with long carbon fiber-reinforced thermoplastic composites, and the fiber orientation was measured at different locations of the plaques. Autodesk Simulation Moldflow Insight (ASMI) software was used to simulate the injection molding of these plaques and to predict the fiber orientation, using the Anisotropic Rotary Diffusion an...

In the current study the effect of nanoclay content and carbon fiber orientation on the buckling properties of epoxy/nanoclay/ carbon fiber orientation is investigated. Buckling samples were prepared with 1, 3 and 5 wt% of nanoclay and 0, 30 and 45 degrees of fiber orientations based on VARTM technique. The results obtained from the buckling tests showed that adding 1wt% of nanoclay into the pu...
