Vulcanization
Within the rubber vulcanising industry autoclaves are used to convert natural rubber into a cured and cross-linked vulcanized rubber product such as tyres, rubber rollers, couplings and other technical items which require ultimate reliability and traceability.
For example, a circle of 60 tubular autoclaves curing parts which required a 60-minute cure would yield one part per minute. Assuming 6-inch diameter flanges for the autoclaves, the circle would be under ten feet in diameter.
The breather ply is able to allow air through it even when compressed. This prevents air pockets from forming far from the valve when vacum bagging. The bleeder is an absorbant material that is there to soak up extra resin that is forced out of th
When autoclave curing parts it is normal to vent the vacuum when pressure gets to 15 - 20 psi. Why is this ? Are there any good reasons to leave the vacuum conn
General Nano and supply chain and OEM partners have developed VeeloHEAT, a lightweight, flexible, uniform heater that the aerospace composites industry is currently evaluating to improve throughput, quality and efficiency for out of autoclave composite processing, composite tooling with embedded heating elements, specialty heaters bonded to metallic tooling, and composite repair.
Typical curing temperature for composite materials is 250 °F or 350 °F. The temperature of large parts that are cured in an oven or autoclave might be different from that of an oven or autoclave during the cure cycle, because they act like a heat sink.

Autoclave curing offers high quality and more uniform part quality due to the collapsing of any air and volatiles inside and between the plies by the increased cure pressure (>30 psi when compared to the roughly 14.7 psi (1 atm)).
As it has been answered in some previous comments, the autoclave cure gives the best results in terms of porosity into the laminate. When the laminate is build by stacking up plies, some air is bound to be trapped between the plies. Intermediate d
CompuDAS has installed composition processing and curing Control Systems for autoclave, out of autoclave, oven and other composite techniques for customers in the most competitive and sensitive trades, including aerospace and automotive manufacture.
Benefits of Using a Nitrogen Generator for Autoclave-Polymer Curing. Originally autoclaves used air, but nitrogen has become the preferred gas for many types of autoclave processes. There are a number of reasons for this. One of the main factors is the availability of nitrogen generators that are economical to have onsite.
Autoclave curing is used to achieve the absolute minimum amount of resin voids when producing composite components maximising strength to weight ratio. This is done by placing the part under vacuum in an autoclave and then pressurising the autoclave during a heated cure cycle.
Actually, during the curing process, when resin flows out from the laminate into the bleeder, a pressure drop is established through the laminate thickness. Furthermore, a fraction of the autoclave pressure is transferred to the fiber stack, characterized by an elastic behavior in compression.

Autoclave - Rubber Vulcanizing. Cardinal Rubber Company has autoclave curing capabilities for rubber vulcanizing. We have various sized cylinders that are used in this process around five foot in diameter and up to 20 feet long which can hold various parts for applying vacuum pressure. During the process, the vacuum provides 29 psi of pressure.
Autoclaves and Nitrogen: Nitrogen's Role in Aerospace Manufacturing. When composite parts are created and cured, the pressure in the autoclave environment puts them into a situation where they become highly flammable due to increased pressure and temperature inside the autoclave. Once cured, these parts are safe and do not pose a fire risk.
Autoclave curing is used for production of external thermal shells of Re-entry vehicle structures of the missiles. Autoclave curing of phenolic composites involves a complex regime of time - temperature -pressure cycle where selection of pressure application point is the most important parameter, decides the

Curing Concrete Test Specimens Curing of concrete test specimens is usually different from concrete placed during construction. American Society for Testing and Materials (ASTM) has developed two standards for making and curing concrete specimens. ASTM C192 6 is intended for laboratory samples while ASTM C31 7 is intended for field samples
Figure 1: Cyanoacrylates on LCP - 50 Autoclave Cycles Light curing acrylics cure via a free radical reaction to form thermoset resins when exposed to light of the appropriate wavelength and intensity. Like cyanoacrylates, light curing acrylic adhesives are available in a wide range of viscosities from low (~ 50 cP) to thixotropic gels.
Autoclave Curing Trimming, inspection, and assembly. Autoclave Cure • An autoclave is a heated pressure vesselthtlll that allows -Vacuum to be drawn in interior region(s) -Heatup and cooldown rates to be precisely controlled -Internal ppppgressure applied using
The usual autoclave cure for sandwich is 35-50 psi. If your core is very light (e.g., 2 lb per cu ft Nomex) it might need a lower pressure. If it's not precured the state of the backing (bag side) skin might be a bit questionable with just 20 psi.
Inside pressurized Autoclave vessels this pressure can be magnified to even greater levels. This predictable and consistent pressure application consolidates laminates and sandwich panel constructions. Airtech provides a comprehensive range of vacuum bag materials and equipment required curing in Autoclave and Oven, including: Bagging Films

Autoclave curing is the process putting products into autoclave to cure in high pressure and high temperature, suitable for high strength cement and foamed concrete. Through this process and the use of superplasticizer, the concrete can withstand the weight more than 1 ton. Drying shrinkage and creep occur less than moist curing concrete. For
Ballistic Armor Autoclave Systems. Ballistic armor is fabricated from a mix of composite materials, steel, silica, and ceramics. In order to increase the quality of the final product, most armor must be bonded and cured in composite curing autoclaves.
Out-of-autoclave (OOA) or vacuum bag only (VBO) prepregs depend on the physical extraction of entrapped air and volatiles to achieve low levels of porosity, a tim e dependent process. Strategies for minimizing the total cure duration are discussed in several

Autoclave for the Curing of Composite Materials Page 2 Project P10229  the goal was to design a system for far less than this. While the full autoclave system complete with a computerized control system was designed, our group was not responsible for building the entire system due to budgetary and time needs. However, the controls,
In this study, an autoclave cure cycle for thick thermosetting resin matrix composite materials was developed to reduce the temperature overshoot. To predict the temperature distribution of thick thermosetting composite laminates during cure, the heat transfer equation, including the heat generation term, was simulated by the finite difference
Each autoclave cycle was around 20 minutes at 250 F (~ 121°C) and about 15 psi of steam pressure. The weight change was then measured periodically, which is illustrated in the graph.
