The early diagnostics of mechanical destruction of polymer composite materials has high importance for practical applications. Fibre-reinforced composites with epoxy matrix and polymers are widely used in engineering. The early undetected damage of these materials could be a reason for catastrophic failure of engineering constructions. Polymeric pipes (polyvinylchloride or polyethylene) have extended applications in drinking water supply systems. Organic compounds can leach from walls of polymeric pipes and serve as a nutrient source for aquatic bacteria. The leach could be promoted due to mechanical loading or destruction of a pipe. The following approaches were researched in order to diagnose the early destruction of polymer composite materials: (1) visual indication of the overloaded area of the materials; (2) detection of electron emission induced by mechanical loading of the materials.
