Vacuum infusion is a method of curing resin into fiber reinforcements by applying vacuum pressure to promote resin penetration and curing. The resin content in the process can vary depending on a number of factors, including material type, process requirements, and application needs.
Typically, the resin content can be controlled between 30% and 40% of the total weight of the fiber reinforcement in vacuum infusion. This means that the weight of the resin accounts for between 30% and 40% of the weight of the entire composite.
However, the specific resin content depends on the materials used and the requirements of the process. Different fiber reinforcements and resin systems may require different resin contents to achieve the desired properties and strength. In addition, specific application requirements may also have an impact on the resin content.
Therefore, for a specific vacuum infusion process, the optimal resin content should be determined based on the material, process specifications, and application needs. Typically, the manufacturer or process expert will provide specific recommendations and guidance to ensure that the appropriate resin content is used in the vacuum infusion process.
