Flbre-reinforced composites with epoxy matrix and polymers are of wide applications in
€ngln€ering.
the early undetected damage of these materials could be a reason of the constructions
6€leBtrophic destruction.
Thc polymer pipes (polyvinylchloride or polyethylene) have extensive applications
in
drlnking-water dishibution systems. The polymer materials have a long lifetime and are
Rot Busceptible to corrosion, organic and inorganic additives being in use to improve
matcrlal durability and lifetime. Polyethylene, polyvinylchloride and the above mentioned
eddltlves tend to leach biodegradable organic compounds. These compounds serve as a
nutrlent source for bacteria; they may react with disinfection agents (like,chlorine,
ehloramine and ozone) and are capable to form carcinogenic substances, water
organoleptic properties (taste and smell) are influenced. The leach could be promoted
dua to mechanical loading of the pipe (thermal and soil shift induced deformations, etc.).
Therefore early diagnostics of the materials overload is of high importance in practical
appllcation.
Thc following approaches were employed towards early diagnostics of the materials
ev€rload: (1)coloured visualization of the overloaded area of the material; (2) detection
ol the emission of electrons as a result of loading of the material.
For coloured visualization the encapsulated leuco dyes and colour developer were used.
Overloading ruptures, the capsules and dyes react with colour developer. Such a reaction'
davelops the colour at the location of the overload. The embedded encapsulated
components are well incorporated with the fibre reinforced composite with epoxy matrix.
Because the overloading at the bulk of the material is invisible, only its surface layer is
avallable for such diagnostics.
fhe detection of the electron emission was employed during the loading of both
composites and polymers that are in use for water pipes.
lho experiments were provided with the dog-bone shaped specimens. Both the coloured
reaction and emission of electrons were detected for the loaded specimens ln slfu.
