Infusion Molding with Reusable Silicone Vacuum Bag

Fiber reinforced polymer (FRP) composites are increasingly being used to make molded parts for a wide variety of industries: automotive (including trucks and off-road vehicles), renewable energy (components such as wind-power propellers), aerospace, marine construction, architectural structures, etc. These composites combine excellent mechanical properties with a low density, and feature high resistance to water, chemical and environmental pressure.

Traditionally, these materials were composed by a fiber like glass, carbon, aramid fibers as well as natural fibers or hybrid materials and other specialty combinations, and by resins like epoxies, unsaturated polyesters, DCPD polyesters, vinyl esters, phenolics, polyurethane and hybrids.

One of the methods to produce FRP composites and hybrid materials is the infusion molding process with the use of disposable plastic bag sheets that are manually placed and assembled by highly skilled operators. This process is extremely time consuming and generates a great deal of waste since every mold requires a change of bagging. In recent years, manufacturers focused their attention on reusable vacuum bag (RVB) membranes that increase productivity, reduce costs (in particular for larger batches) and improve the quality and consistency of parts produced. This process also contributes to better industrial safety and workplace cleanliness, while reducing the use of consumables and thus lowering waste.

However, because introducing RVBs into a production process can require capital investments and process changes, it is essential to choose the right technologies and products from the start. Depending on these choices and the composites being processed, RVBs can be reused from 20 to 300 times.
