A method is provided for forming a near-net thermoplastic composite component includes co-spraying a mixture comprising a thermoplastic polymer material and a chopped reinforcing material deposited onto at least one region associated with a tool having a first temperature and defining a near-net component shape. The mixture and adjacent tool is heated to a second temperature while the mixture is on the tool. The first temperature is below the solidification temperature of the thermoplastic polymer material and the second temperature is above the solidification temperature. Then, the mixture is exposed to a negative pressure to promote removal of gases from the mixture and put under compressive force to densify the mixture. The thermoplastic polymer material melts and flows. The tool is cooled to the first temperature and removing the mixture to form the near-net thermoplastic composite component having randomly oriented chopped reinforcement material distributed within a thermoplastic polymer matrix.

A process for producing a polymeric stiffened sheet-like component, for example a panel, for aircraft construction. Production includes integration of hollow stiffening profiles, for example closed omega stringers, onto a sheet-like component, for example an external skin, where the stringers and external skin are produced from thermoplastic composite material. The stringers are integrated onto the external skin by establishing contact between the stringers and the external skin and melting thermoplastic composite material with exposure to heat and pressure at the areas of contact between external skin and stringers. Melting of the other sections of the stringers is avoided with a pressurized cooling fluid with a temperature significantly below the melting point of thermoplastic composite material, the fluid flowing through the airtight enclosed space in the stringers. Use of closed airtight thermoplastic omega stringers allows integration of the stringers onto the external skin in absence of any flexible tube within the stringers.
