"Lightweight Flexible Nonlinear Composite (LFNLC)"and Elastic Composite, Reinforced Lightweight Concrete(ECRLC) as an LFNLC

"Lightweight Flexible Nonlinear Composite (LFNLC)" refers to a particular class of high-performance composite materials having their own structural and functional criteria such as the "porous or porous-like texture" and "nonlinear behavior in bending". - "Elastic Composite, Reinforced Lightweight Concrete (ECRLC)" is a cementitious LFNLC. By its use in making the beams with "a substantially high strain capability, modulus of resilience and toughness in bending", we can provide "a significantly higher bearing capacity in considerably less weight". Meanwhile, any possibility of a brittle, compressive failure mode, especially in ultra-lightweight and low-height beams, is eliminated. - The ECRLC, as a lightweight resilient composite, is a versatile, comparatively inexpensive material. Likewise, these virtues are important in architecture: lightness, durability, resilience and flexibility, workability and high formability. - Considering the strategic importance of "lightweight and integrated construction" in improving earthquake resistance, ECRLCs can be especially useful in "seismic areas". Allowing for the behavior and resilience of this flexible system and its formability, it can also be utilized in making "ultra-lightweight and insulation, Non-Brittle reinforced sandwich panels"; lightweight, safe guards; shock-resistant structures; some infrastructures; and blast-proof pieces with appropriate behavior, resilience and toughness. - This work also implies an innovative, applied method "to convert a rigid solid into a flexible material with less density" or "to raise the elasticity of a flexible material plus reducing the density". This practical method principally involves "creating a porous or porous-like texture" along with "appropriately reinforcing the material" and "providing the essential integrity". (Creating the porous or porous-like texture is done by "generating disseminated appropriate hollow pores" and/or "dispersing suitable lightweight aggregates" throughout the reinforced conjoined matrix.) In this way, the resilience in bending increases and the density decreases. - Here, the main structural and functional particulars of LFNLCs, some applications, and “a Reproducible, simple example of the ECRLC” have been briefly presented.
