Composites for Aerospace: Faster More Automated

With infrared the operator has no control over the lamp’s output or the composite material’s temperature leaving him to make an educated guess about the consolidation process. “With IR heating what you can control is two steps away from what you want to control” said Langone who started at the company in 1988 as a college student.
