内容简介

When Composites Atlantic Ltd. (CAL, Lunenburg, Nova Scotia, Canada) contracted to produce 10 types of parts for leading edge and rudder components and deliver them on a biweekly schedule to a key aerospace customer, trouble soon cropped up. "We had slipped dangerously behind schedule in manufacturing and deliveries," says Severine Guitton, CAL's head of quality and methods. Debonding between two plies of aramid material in four of the parts was discovered using ultrasound methods. In the case of one leading edge part, the scrap rate had reached 13 percent, and rework, 28 percent. Guitton says there was no logic to the defects because manufacturing procedures were constantly checked and found to be in compliance with quality requirements. The issue jeopardized the customer's confidence, notes CAL's COO Derek Kinsman.
