Method of forming thermoformable composite material. |
摘要 |
<p>In a method of forming a body of thermoformable composite material using two shaping diaphragms against the shaping surface of a tool, the diaphragms are selected to be of different stiffness. Improvements in the control of the uniformity of thickness and/or buckling can be achieved depending upon which of the diaphragms is stiffer relative to the tool side of the assembly being formed.</p> |
