How does vacuum bag silicone rubber work?

Thanks to silicone rubber's flexible and stable chemical properties, silicone rubber is more and more popular for vacuum bagging.

ADVANTAGES OF SILICONE RUBBER VACUUM BAG IN NEW COMPOSITE MATERIALS:

Silicone rubber vacuum bag not only solves the problem of difficult one-time molding of composite materials in the past, but also makes it possible to make composite materials with large size, which can increase the fiber content of composite products and reduce the porosity; As the vacuum bag made of silicone rubber has good performance characteristics, it can be reused for many times, solving the problem of one-time use of plastic vacuum bag and resin vacuum bag, effectively reducing the production cost of composite materials, and improving the production efficiency of composite materials and the integrity and stability of products.

OPERATION PROCESS OF SILICONE RUBBER VACUUM BAG:

The silicone rubber vacuum bag molding process is to make the product more dense, improve the fiber resin ratio and improve the mechanical properties by vacuuming and evenly applying pressure on the preform sealed between the mold and the silicone rubber vacuum bag.

GENERALLY, VACUUM BAG FORMING PROCESSES ARE DIVIDED INTO TWO CATEGORIES:

1. Popular name - wet vacuum bag process, that is, first pave the reinforcement materials containing saturated resin, and then vacuumize them. Typical examples are prepreg process and hand lay up bag pressing process.

2. Popular name - dry vacuum bag process, that is, vacuum resin introduction process, laying and covering dry fiber, and injecting resin after vacuum bag pressure holding.
