The key features of this process are as follows:

• An autoclave is a closed vessel for controlling temperature and pressure is used for curing polymeric matrix composites.
• Composites to be cured is prepared either through hand lay up or machine placement of individual laminae in the form of fibers tape which has been impregnated with resin.
• Components is then placed in an autoclave and subjected to a controlled cycle of temperature and pressure.
• After curing, the composite is “solidified”.
• One can use the fibres like carbon, glass, aramid etc. along with any resin.

Advantages:

• Large components can be fabricated.
• Since, the curing of matrix material is carried out under controlled environment, the resin distribution is better as compared to hand or spray lay-up processes.
• Less possibility of dilution with foreign particles.
• Better surface finish.

Disadvantages:

• Initial cost of tooling is high.
• Running and maintenance cost is high.
• Not suitable for small products.

Applications:
The process is suitable for aerospace, automobile parts like wing box, chassis, bumpers, etc.
