curing cycle meaning in Hindi

Examples

1. Epoxies also allow shorter cure cycles, increased durability, and improved surface finish.
2. The process allows for more repeatability in cure cycles, and rapid heating allows for improved inter-laminar properties and improved surface quality.
3. Too heavy a wall thickness, on the other hand, will slow the curing cycle and add to material cost and increase cycle time.
4. Further advances in the acrylic compounds used decreased the curing cycle times to below 5 seconds in many cases, which is where they remain as of this writing.
5. This is a very common process in the aerospace industry because it affords precise control over moulding due to a long, slow cure cycle that is anywhere from one to several hours.
6. The curing of composites requires compacting the piles of material, pressing this material against the mold, forcing out volatiles and excess resin, and holding everything motionless during the entire cure cycle.
7. A typical curing cycle involves a preheating stage, known as the " delay period " ranging from 2 to 5 hours; heating at the rate of 22 �C / hour or 44 �C / hour until a maximum temperature of 50 " 82 �C has been achieved; then maintaining at the maximum temperature, and finally the cooling period.
8. In more elaborate arrangements, there may be a dozen or more individual vacuum supply lines going into the machine, each to a separate QD port, with as many gauge lines coming back out to vacuum sensors wired to the control system, and an inert gas backfill under controlled pressure for when the pump is shut off and the vacuum lines vented during the cure cycle.
9. The quickstep out of autoclave system is unique in that it uses fully immersed balanced pressure fluid curing and it allows the user to stop the composite cure reaction at any point in the cure cycle, and thus can halt processing on all or part of the laminate and either return to it at a later to complete cure or to co-cure, join and bond other composites to it to create larger parts.
10. The most important technical challenges in the implementation of a successful composite patch repair are : ( a ) proper design of the repair patch and the procedures that will be followed, ( b ) selection of the most suitable materials and tools for the application, ( c ) careful surface preparation ( d ) implementation of the composite patch repair and careful application of the cure cycle, ( e ) non destructive evaluation of the repair by suitable methodology and ( f ) monitoring of the structural integrity of the repair either at specific time intervals either continuously.
