Abstract
A method for forming a thermoplastic laminate having a desired laminate thickness is disclosed. Layers of composite material using precured or partially precured thermoplastic resin laminate layers are layed-up on a forming tool. A relatively constant, uniform pressure is applied to the layers to produce a preconsolidated laminate having a thickness approximately equal to the ultimate desired laminate thickness. The laminate layers are free to slide relative to one another during debulking because they are either cured or partially cured. Thus, wrinkles are avoided. The debulked laminae are then consolidated in a conventional autoclave under elevated temperature and pressure.
