Mechanical properties and conductance behavior of fiber glass investigated by different physical methods

Fiber glass belongs to polymer metrics composites (pmcs), possessing good resistance to corrosion and oxidation . this work reports stress, strain and young’s modulus on fatigue strength of fiber glass measured by universal testing machine (utm) method. the results show that the value of stress and young’s modulus increases with increasing concentration, while that of strain decreases. moreover, micro structure analysis, hardness and conductance were measured by automatic vickers micro hardness testers. as a result, interesting behaviors of these parameters were recorded. the ca(oh)₂ doping significantly increase the conductance of composite material. the highest conductance was observed at 35 wt% ca(oh)₂ concentration showing conductivity value of 3.98×10⁻⁴ s cm⁻¹. the micro hardness analysis of polymer composite with 35 wt% ca(oh)₂ concentration showing higher conductance.
