here Compaction is the process of bringing the individual fibre’s close to each other so they can transfer load to each other more effectively. Compaction plays another role of removing any trapped air that may cause voids or porosity in the laminate. Compaction is very important because for the structure to perform as designed the individual fibre’s need to transfer the loads from one fibre to the next so the load can travel through the structure. The resin has strength and stiffness properties of about 1% of the fibre so it is important that the fibre can do the job it was intended to do. There is a misconception that compaction is only important to remove the excess “heavy” resin to reduce the weight of the part. This is false in that proper compaction provides not only a decrease in weight but an increase in strength and performance. The overall laminate will have lower strength than a properly consolidated laminate having the optimal per ply thickness, and will generally require more plies to achieve the desired strength”.
