This system is designed to augment the majority of commonly used chopped glass fiber spray-up machinery. The system consists of a mechanized hopper/feeder and a pneumatic delivery tube. The bio-material is used to offset some virgin glass fiber or as a core filler. It can replace a significant amount of glass fibers when fibers are used as a bulking material to increase the thickness of a composite part. It can also be used as a core filler to replace commonly used balsa and foam sheets. As a core material, it has an advantage over balsa and foam as it can easily and quickly apply core material onto complex curved geometries.
