Disclosed embodiments provide automated fiber placement techniques for fabrication of parts made from composite materials. A peening system with multiple pins provides compaction over irregular surfaces, providing superior performance as compared with traditional compaction rollers. The apparatus that carries out the techniques include a tape dispensing system, a heating system, a peening system, a processor and a memory coupled to the processor. The memory contains instructions that when executed by the processor perform the steps of: dispensing a first ply of thermoplastic composite tape over a mandrel; dispensing a second ply of thermoplastic composite tape on the first ply; and peening the second ply onto the first ply, such that the second ply is bonded to the first ply.

A method for altering adhesion properties of a surface of a substrate by a coating, comprising the steps of: a) ionizing a plasma gas at low temperature and at atmospheric pressure, thereby creating a plasma with a plasma temperature of at most 50° C.; b) introducing a precursor into a plasma gas afterglow of the plasma; c) subjecting the surface of the substrate to the plasma including the precursor, thereby forming a coating onto the surface. The plasma gas is essentially completely comprised of inert gas. The coating alters the adhesion properties of the surface.
