panel is conformed or juxtaposed to a tool surface and
subsequently cured via heating. An understanding of the
invention can be derived from a reading of exemplary claims 1
and 11, which are reproduced below.
1. Method for fabricating polymer panels
with apertures, comprising the steps of:
providing a flat polymer panel, partially
cured to a state in which the panel can be
handled as a rigid sheet at room temperature;
drilling a plurality of apertures into said
partially cured panel to produce a partially
cured perforated sheet;
juxtaposing a surface of said partially
cured perforated sheet with an elastomeric tool
surface having a shape conforming to a desired
final shaped of said panel;
while said perforated sheet is juxtaposed
with said elastomeric tool surface, heating said
perforated sheet sufficiently to completely cure
said perforated sheet; and
removing said cured perforated sheet from
said tool surface.
11. A method for producing a perforated
acoustic article, comprising the steps of:
providing an uncured sheet of polymer
material;
partially curing said uncuring sheet to a
form in which the resulting partially cured
sheet can be handled as a rigid sheet at room
temperature;
drilling a plurality of apertures in said
partially cured sheet to form a partially cured
perforated sheet;
preheating said partially cured perforated
sheet to make it flexible;
