... into a structural shape. A typical thermoforming setup is shown in Fig. 6.5 . The first step in thermoforming is to collate the ply pack. The collated ply pack could then be preconsolidated into a flat laminate or the thermoforming operation could be conducted using the unconsolidated ply pack. There is some...

... been considered. (Use of preforms is common in the P/M field; pre-consolidated billets—from HIP or extrusion—are common in the superalloy field.) Preconsolidated billets are used as stock for the isothermal forging of aircraft gas turbine components. Conventional CP plus sintered BE P/M titanium...

... lower than normal HIP runs. To process preconsolidated C-channels into spars, as shown in Fig. 9.29 , they can be joined together in a back-to-back fashion. For secondary diffusion bonding in a HIP chamber, the parts are assembled and encapsulated in a leak-free steel envelope or bag. Because the bag...
