Abstract

The aerospace industry has pioneered the use of automated material placement machines, which excel in placing fibres in straight lines on large-scale moulds. Nonetheless, their ability to produce curved paths, which are required for complex doubly curved shapes and more efficient load distribution, is extremely limited. In order to overcome this limitation, the Continuous Multi-Tow Shearing (CMTS) process was developed, where in-plane shear deformation is employed in order to steer the tow path. The CMTS utilises unidirectional (UD) carbon fabric with multiple tows in the form of a tape.
In this paper two different materials were tested with a CMTS prototype head and a qualitative analysis was performed in order to give insight into the effect of material parameters on the quality that can be achieved with the process.
