Layered-Fabric Materiality Fibre Reinforced Polymers (L-FMFRP): Hysteretic Behavior in Architectured FRP Material

Area of Science:

• Materials Science
• Structural Engineering
• Architectural Design

Background:

• L-FMFRP is an innovative architectural fiber composite surface element.
• It features an airy internal structure and variable section, created through an alternative design and fabrication process.
• This process integrates fabric materiality, allowing for moldless shaping via pleating and layering.

Purpose of the Study:

• To further investigate the hysteretic capacities of L-FMFRP.
• To examine the material's behavior under repeated loading.
• To understand the effect of its internal material architecture on its properties.

Main Methods:

• Experimental investigation of L-FMFRP under repeated loading conditions.
• Analysis of the material's internal architecture and its influence on mechanical properties.
• Comparative study with entangled materials to understand hysteretic behavior.

Main Results:

• L-FMFRP exhibits unique hysteretic behavior under mechanical stress.
• The internal material architecture significantly affects the composite's structural performance.
• The material's behavior satisfies requirements for schematic architectural cladding configurations.

Conclusions:

• L-FMFRP demonstrates significant hysteretic capacities, influenced by its internal architecture.
• The material shows potential for future application as an energy-absorbent material in façade cladding.
• Further research into parallels with entangled materials can deepen understanding of its energy-absorbent mechanisms.
