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)
