Technology of A- and B-basis allowable power values are essential for minimizing possibility in aircraft structural elements produced from fiber strengthened polymer composite components.Hazard reduction is realized by reducing the chance of failure of crucial aircraft structures from the utilization of A- and B-basis design values.
