TEQC83 covers the proceedings of the International Conference on the Testing, Evaluation, and Quality Control of composite materials. The 31 papers included in the book cover topics within the general areas of mechanical testing, materials characterization, non-destructive testing, quality assurance and structural analysis, and environmental testing. Experimental techniques for measuring fiber/matrix interfacial bond shear strength; prediction of notch-tip energy absorption in composite laminates; an X-ray radiography study of delamination growth in notched carbon/epoxy laminates; and quality assurance in a production environment are examples of papers included in the book. The book also presents topics, such as influence of processing on the water aging of unsaturated polyester-based composites; the determination of interlaminar fracture toughness and fracture mode dependence of composites using the edge delamination test; and pattern recognition in ultrasonic testing of fiber reinforced plastics. Design engineers will find this book helpful.
