Precision of Rate-Process Method for Predicting Durability of Adhesive Bonds

Source

The influence of such experimental variables as time, temperature, adhesive type, specimen heterogeneity, and moisture conditions on life-expectancy forecasts was explored under two environmental moisture extremes—dry and water-soaked. The data indicated that there could be a rather broad error band associated with these projections. Use of the lower 95 percent confidence limits, however, provides a positive means for estimating minimum bondline durabilities. With proper attention to experiment design, the rate-process method can provide durability forecasts well within the needs of most applications. Maximum sensitivity is attained under wet aging conditions.
