Assessment of polymer composite reinforced with nanomaterial against ionizing radiation
Introduction: Unwanted exposure of ionizing radiation may result in carcinogenesis, cell mutations, and organ failure. High-atomic number elements such as lead, tungsten, bismuth have been traditionally used for radiation protection. Theoretical and practical studies have shown that a variety of shielding materials e.g. polymer composites (PCs) can be used for attenuation of th...
متن کاملAn Experimental Investigation on Fracture Analysis of Polymer Matrix Composite under Different Thermal Cycling Conditions
Fracture analysis of glass/epoxy composites under different thermal cycling conditions is considered. Temperature difference, stacking sequence, fiber volume fraction and number of thermal cycles are selected as the experimental design factors. The Taguchi method is implemented to design of the experiment and an apparatus is developed for automatic thermal cycling tests. The tensile tests are d...
متن کاملHierarchically constructed metal foam/polymer composite for high thermal conductivity
Most polymeric tribological components are inherently insulative, resulting in susceptibility to failure from frictional heating at the PV limit, which is typically reported as a product of the heat flux terms pressure (P) and sliding speed (V). This letter reports on the design of a tribological composite for increased thermal conductivity and PV limit. The control sample is an unfilled compos...
متن کاملSynchrotron radiation computed laminography for polymer composite failure studies
Synchrotron radiation computed laminography is applied to the three-dimensional micro-imaging of damage in large polymer composite plates with high spatial resolution. The influence of different experimental conditions is studied with respect to measurement time optimization, dose minimization and reduction of artefacts in the reconstructed images. Failures like delaminations, transverse ply cr...
متن کاملPolymer Composite Reliability
The structural performance, reliability and durability of polymer composites can now be correlated with three generic classes of internal defects. The _first generic class of chemical structure defects (size 10-lOOA) that control critical design properties such as glass transition T 0 , moisture absorption, and dimensional changes can be controlled by chemical analysis of raw materials prior to...
