elastomer softness and good compression
properties make them an excellent
choice for gaskets. Microwave
absorbing versions are also available
along with significant experience
comolding absorbers. This is an elastomer
of choice for many aircraft
applications.
* Another prerequisite is sophisticated
manufacturing capabilities to ensure
each comolded solution has the right
mix of materials to meet the precise
specifications of different aerospace
and defense applications. This
includes tooling and layup procedures
to produce manufacturable parts.

a factor, fabrics like Nomex and Dacron
can be molded into the outside of the gasket.
These fabrics can greatly increase tear
and tensile strength of the gasket as well
as provide excellent resistance to abrasion
of the outside elastomer surface. Finally,
the fabrics can improve the coefficient of
friction of the mating surfaces, thus
ensuring longer gasket life.
As illustrated by these examples, the
key prerequisites for successful comolding
are:
* Detailed knowledge of materials and
their performance under various conditions.
For example, use of fluoroelastomers
can provide temperature
resistance to 475°F as well as excellent
fluid resistance. Like silicones, fluoro*
The last prerequisite is sophisticated
FEA analysis tools for both mechanical
and electrical analyses to ensure
initial designs can meet the requirements
before the tooling is produced.
To ensure the reliable operation of
aerospace and defense electronics, it's
crucial that design engineers leverage
multifunctional solutions to address
increasingly complex signal challenges.
Comolding is a key enabler of these
integrated and innovative packages.
