Experimental evaluation and ANN based prediction model for dynamic properties of epoxy glass fabric composites with natural rubber particle inclusions

摘要

Conventional materials are being replaced by composite materials due to their tailorable properties and high specific properties. In almost all the fields these materials are found in many applications. Damping is one of the important properties of the materials used in structures is to be enhanced to reduce structural vibrations. In the present work improvement of material damping of glass fabric epoxy composites with particle rubber inclusions is studied experimentally. Considerable enhancement in damping without significant reduction in stiffness is observed at lower particle size. ANN based prediction model is developed to predict these properties at a given frequency/temperature and particle size.
