The adopted reinforcement should mimic the compression behavior of those used to fabricate prepregs, usually compressed either during impregnation either during lay up, vacuum bagging and
autoclave curing, so that the volume fraction of fiber ([V.sub.f]) is close to 60%.
The operation produces complex composite structures utilizing the latest carbon material and
autoclave curing technology.
High strength concrete could be achieved by incorporating ground quartz sand and fine stone dust as a partial cement replacement in an
autoclave curing system (Jaafar et al.
Autoclave curing is required for certain types of high-performance composites.
The widespread method of
autoclave curing, it says, makes part handling complicated, the process is time-consuming, and the quality of process control is not satisfactory.
Techniques include pressure moulding and high temperature
autoclave curing.
Finally, a production part may be cured under pressure as in compression, transfer or injection molding, under pressure as in
autoclave curing, or without pressure as in LCM or microwave and hot air curing.
Autoclave curing temperatures greater than 800F (412C) are easily handled by the nickel tooling.
With the possible exception of the extremely low operating temperature of the focal-plane environment described elsewhere, the
autoclave curing cycle, encountered during fabrication, is probably the most severe environment to which the interconnects (and the other integrated optical components) will be subjected.
