Process autoclave

Composite autoclaves are used to manufacture composite materials in a variety of industries, especially in motorsport, aerospace and automotive industries. This equipment allows controlled heat and pressure to be applied to composite materials during the curing process, which involves subjecting resin-impregnated carbon or glass fibres to high temperatures and specific pressures to harden them and form the final part with the desired properties. The autoclaves are designed according to the highest European and American quality standards, as well as regulations such as NADCAP and BOEING D6-49327, among others. Manufacturing cycle The basic manufacturing cycle consists of introducing the mould with the carbon fibres or glass fibre into the autoclave and then subjecting it to controlled temperature and pressure. The heating and pressurisation process can be divided into sub-steps until the desired values are reached, which will remain stable for the programmed time. The autoclave is then depressurised and cooled so that the moulds with the parts can be removed. In addition, the moulds with the fibres can be placed inside vacuum bags, where air trapped inside the mould and between the layers of composite materials is removed. This air can cause defects in the final part, such as porosity or lack of consolidation between the fibre layers and the resin. The temperature control of the autoclave can be made dependent on the mould temperature by inserting flexible temperature probes into the mould.
