AbstractObservation of behaviour phenomena of ultrasonic waves in an object allows for quality assessment, identification and location of discontinuity. Physical nature of acoustic processes is based on propagation of mechanical waves constituting a disturbance of equilibrium of the state of material. The acoustic process identified by selected characteristics can be a source of information about state of material, its structure, and properties, which is particularly important for systems exhibiting anisotropy properties, and such are layered polymer composites. They are special materials because their properties depend greatly on the manufacturing technology. Therefore, while conducting acoustic tests which use the influence of elastic properties and homogeneity of material structure for propagation of sound waves the adopted method of measuring characteristics which identifies propagation of ultrasonic wave phenomenon is of particular importance. The aim of the work was quality evaluation of layered polymer composites made by winding and press moulding by the method of echo and C-scan, using head Phased Array. Composites have been tested by thermal and fatigue degradation. Quality evaluation has been made based on the transition time of the ultrasonic wave and the bending strength.

Analysis Of Results

In this research article, the assessment of properties of compression moldedGrewia optivafiber reinforced Urea-Formaldehyde (UF) matrix based polymer composites is reported. Reinforcing of the UF resin withGrewia optivafiber was accomplished in the particle, short and long fiber reinforcement. Present work reveals that mechanical properties such as: tensile strength, compressive strength and wear resistance of urea - formaldehyde resin increases to a significant extent when reinforced withGrewia optivafiber. Analysis of results shows that particle reinforcement is more effective as compared to short and long fiber reinforcement. Morphological and Thermal studies of the matrix and fibre reinforced biocomposites have also been carried out
