Mastering the Layup Technique for Resin Infusion using DANU Composites

Resin infusion is a popular technique for creating composite parts, and when done correctly, it can lead to parts with improved properties such as higher strength-to-weight ratio and improved durability. One of the key steps in the resin infusion process is the layup of the composite material. In this article, we will focus on layup for resin infusion using DANU, a brand of composite material, as the main composite material.

Before beginning the layup process, it is important to properly prepare the mould and make sure all necessary materials and tools are on hand. This includes cleaning the mould, ensuring that all release agents are applied correctly, and having a suitable vacuum bagging system in place.

When using DANU, the first step in the layup process is to cut the material to the desired dimensions, considering any necessary overlap for the vacuum bagging process. The DANU material should then be placed into the mould, taking care to ensure that it is smoothed out and free of any wrinkles or bubbles.

Next, a layer of perforated release film is placed on top of the DANU material, followed by the placement of the breather fabric and vacuum bag. The vacuum bag should be sealed tightly, taking care to ensure that there are no leaks in the system.

Once the vacuum bag is sealed, the mould is placed into the vacuum bagging system and a vacuum is pulled, removing all of the air from within the bag and the mould. This process compacts the DANU material and ensures a tight fit against the mould, resulting in a higher-quality composite part.

After the vacuum bagging process is complete, the resin infusion process can begin. The resin should be heated to the appropriate temperature and infused into the mould, typically through a tube or other conduit. As the resin flows into the mould, it should be monitored for proper distribution and for any signs of air entrapment.

After the resin infusion process is complete, the mould should be allowed to cure according to the manufacturer's recommendations. Once the composite part has cured, it can be removed from the mould and any necessary post-processing can be performed.

In conclusion, the layup is an essential step in the resin infusion process and is critical to the quality of the final composite part. When using DANU as the composite material, proper preparation of the mould, accurate cutting of the material and correct application of vacuum bagging and resin infusion are the keys to success. With the right techniques and attention to detail, it is possible to create high-quality composite parts with DANU and resin infusion.
