Detonation waves will bypass a wave shaper and propagate in the form of a horn wave in shaped charge. Horn waves can reduce the incidence angle of a detonation wave on a liner surface and collide with each other at the charge axis to form overdriven

The milling process is always required to achieve dimensional tolerance for the near-net-shape carbon fiber reinforced polymer (CFRP) parts. However, delamination and cracking are inevitably induced in milling CFRP due to the excessive milling forces

The burrs and delamination induced in milling of carbon fiber reinforced polymer have been studied extensively to suppress them. The cavity defect is still generated frequently on the machined surface of carbon fiber reinforced polymer when the fiber
