Abstract
The main aim was to measure and evaluate the absorption ability of resins in
glass fiber mats most often used in Hungary since pore size influences the
absorbance process and the absorbed quantity of resin during composite
production when the resin is still in a liquid phase. The average value of
pores and their distribution function were estimated using the mat statistic
model and the measured geometrical parameters. The measurement and
evaluation method developed can be used to model the liquid absorbance
process of glass fiber mats and to measure the mass of absorbed resin and
the rate of absorption. A good theoretical approximation was also obtained
for describing the resin absorbency of glass fiber mats. It was found that
there is a linear relationship between the pore sizes estimated with the
help of the statistic fiber mat model and the uptake rate
