1Object-generated harmful factors
If natural fibers are used in bio-composites, then environmental sustainability is improved, but mechanical strength and thermal stability deteriorate
Solution Approach 1:
The patent creates a composite material system combining natural fibers with carbon nanomaterials (carbon nanotubes, graphene, or carbon nanofibers) to achieve both environmental sustainability and enhanced mechanical strength. The carbon nanomaterials act as reinforcing agents that compensate for the inherent weakness of natural fibers while maintaining the eco-friendly nature of the composite.
Solution Approach 2:
The patent modifies the physical and chemical parameters of natural fibers through surface treatment and optimization of fiber dimensions (length, diameter) to improve their mechanical properties and compatibility with carbon nanomaterials, thereby enhancing overall composite strength without compromising sustainability.
2Object-generated harmful factors
If natural fibers are used in bio-composites, then environmental sustainability is improved, but thermal stability deteriorates
Solution Approach 1:
The integration of carbon nanomaterials with natural fibers creates a composite structure that leverages the excellent thermal stability of carbon-based materials to compensate for the low thermal resistance of natural fibers, enabling the composite to maintain structural integrity at higher temperatures while remaining environmentally sustainable.
3Strength
