Properties Of Materials

The measurement of thermal parameters is a useful tool for the evaluation of compositional or structural properties of materials of industrial interest. The increasing use of noncontact photothermal techniques to generate and sense thermal fields in materials makes thermal characterization an attractive approach for in-plant quality monitoring and process control. In an effort to increase the reliability of such measurements in conditions of unknown surface emissivity, an integrating-cavity technique is described for a quantitative evaluation of the thermal inertia of the inspected material. An analysis of the performance of such a technique as a function of the cavity geometry and internal reflectivity is presented. Examples of applications to the characterization of manufactured ceramic materials with different porosity contents are described.

Different Types

Photoacoustic Spectroscopy (PAS) stand outs among Photothermal techniques due to its versatility for the characterization of different types of materials, including biological samples. In this study, were compared and analyzed by PAS, the differences between the optical absorption spectra of blood of male Fisher rats, in three cases, control (healthy rats), liver damage and liver damage treated with Curcuma longa. The experimental results show differences in the optical absorption spectra of each analysed case, therefore PAS would be proposed as a non conventional complementary technique, to study the effect of Curcuma longa in induced liver damage for an animal model.

Banana Fibers

Synthetic fibers are being replaced gradually by natural materials such as lignocellulosic fibers. Compared to synthetic fibers, natural fibers have shown advantages in environmental, societal, economical and technical aspects. Thus, there is a growing worldwide interest in the use of those fibers. The banana fiber, extracted from the pseudo-stem of the plant, displays significant properties yet to be studied. Few thermal properties on banana fiber as reinforcement of epoxy matrix were fully evaluated. Therefore, the present work had as its objective to investigate, by photoacoustic spectroscopy and photothermal techniques the thermal diffusivity, specific heat capacity and thermal conductivity of epoxy composites reinforced with banana fibers .The epoxy matrix was added with up to 30% in volume of continuous and aligned banana fibers. The results indicated that these composites have good insulation capacity.
