Multiscale Natural Fibres and Architected Reinforced Thermoplastics

Abstract

Plant fibres composites (PFCs) have lately gained significant interest due to their environment friendly aspects and enhanced physical and mechanical performances. A subcategory of PFCs that uses thermoplastics has become widespread with the advent of the additive manufacturing industry. This work is focused on the investigation of the thermoformability of PFCs made using two techniques: hot-press thermoforming and 3D printing. The hot-press technique is widely used by researchers and industrials, whereas 3D printing is celebrated as a technique that can produce very complex shapes in a relatively facile manner. The main goal of the work here is to explore the ability of each technique to produce PFC objects without requiring elaborate setups. Another objective is to assess their integration, alongside the use of other assistive techniques and tools like a vacuum bagging and oven. These assessments have been aimed at achieving better manufacturing outcomes, such as a lower fabrication time.
