Singum modeling for hybrid lattice materials in absorbent products
Innovative singum modeling approach for hybrid lattice materials enhances the design and mechanical performance of absorbent products like diapers and menstrual pads by simulating SAP particle interaction and mechanical properties under various conditions.
Overview
This solution presents an advanced singum modeling approach designed to optimize the mechanical performance and design of hybrid lattice materials used in absorbent products such as diapers and menstrual pads. The core innovation is the integration of superabsorbent polymer (SAP) particles within a 3D textile lattice, enhancing absorbency and structural integrity. By examining the interaction of SAP with the lattice, this model predicts the prestress and mechanical behavior of the material, offering a new paradigm for product design.
Technical specifications
- Singum Model: A novel framework that homogenizes a singular force network into a continuum, allowing for accurate stress-strain predictions in lattice materials.
- Hybrid Lattice Structure: Combines a granular lattice with a cellular lattice, confined by a boundary layer to manage prestress initiated by SAP volume increase.
- 3D Modeling: Utilizes a primitive cell approach to simulate force-displacement relationships, supporting continuum mechanics-based modeling for enhanced product design.
- Application in Product Design: Enables the creation of more efficient and reliable absorbent products through precise modeling of mechanical properties and material behavior under varying environmental conditions.
Technology readiness level
Currently at TRL 3, this technology has been validated through significant academic research and publications. Ongoing efforts focus on further exploring cellular lattice behaviors, SAP interactions, and the effects of environmental factors such as heat and moisture. Future development includes the application of this model in the design and manufacture of absorbent products via 3D textile technologies.
