JEC World 2019 preview: Fives
Fives (Cincinnati, Ohio, U.S.) will be presenting its next-generation sensor for in-process inspection of carbon fiber-reinforced layups, reportedly capable of reducing processing time by up to 30% compared to layup operations using manual inspection.
The sensor, co-developed by Fives’ Seattle location and Conseil National de Recherches Canada (NRC, Ottawa) employs optical techniques adapted from medical imaging applications. NRC holds the basis patent and has licensed it exclusively to Fives for composite applications.
In tests conducted over the past 18 months on a Cincinnati Viper 4000, the sensor has reportedly demonstrated significantly improved results over Line Laser Triangulation (LLT).
According to Fives, the sensor is able to track complex surfaces, measure and characterize parameters previously impossible to capture on-line, and measure consistently over different materials. The packaging of the unit is said to improve integration with the fiber placement head, enabling real-time measurement at the point of fiber placement, and the data analytics capability enables the manufacturer to characterize aggregate properties of the defects, such as spatial distribution.
As the wind energy market continues to grow, competition heats up between glass and carbon fiber composites for turbine blades.
Approaching rollout and first flight, the 787 relies on innovations in composite materials and processes to hit its targets
The structural properties of composite materials are derived primarily from the fiber reinforcement. Fiber types, their manufacture, their uses and the end-market applications in which they find most use are described.
