Distributions of surface height and in-plane strain of an angle interlock C/SiC composite at 1,200°C, measured by DIC. Line scans (in red) are used to correlate strains with the underlying fiber weave. (Material provided by D.B. Marshall, Teledyne Scientific.) Credit: Frank Zok; UCSB. Last August DARPA conducted the second test flight of its hypersonic technology…
