Aircraft Glazing Materials. Resistance to Crack Propagation. Glazing Materials.
Abstract
The toughness of stretched acrylics measured in terms of the work for crack propagation is discussed in relation to improvements in serviceability of aircraft canopies. A test method for measuring the resistance to crack propagation is described. The use of a birefringence test in quality control is also discussed. (Author)
