Life prediction of glass fiber reinforced plastics based on BP neural network under corrosion condition
The factors affecting the service life of composites were analyzed by the changes of macroscopic
microscopic and mechanical properties before and after aging of glass fiber reinforced plastics under corrosive conditions. The analysis shows that the service life of fiberglass reinforced plastics under corrosion conditions is affected by three factors of temperature
time and corrosion medium concentration. Based on the bending strength retention rate of composites
a three-layer BP neural network model with a structure of 3-10-1 is used to predict the service life of composites. Through the comparison and error analysis of the forecast data and the measured data
and the random extraction of 6 sets of test data for detection
the results show that the predicted value obtained by BP Neural network model has a good fitting fit with the measured value.
