Abstract
Official abstract text for this publication.
A process for making a layered multi-material structural element having controlled mechanical failure characteristics. The process includes the steps of: supplying a cementitious layer and forming a polymer layer on the cementitious layer by additive manufacture such that the polymer layer has a first thickness and the cementitious layer has a second thickness, wherein the polymer layer comprises a polymer and the cementitious layer comprises a cementitious material; and allowing the polymer from the polymer layer to suffuse into the cementitious layer for a period of time to obtain a suffused zone in the cementitious layer such that the suffused zone has a third thickness that is less than half the second thickness.
First claim
Opening claim text (preview).
We claim: 1. A layered structural element having improved mechanical properties, comprising: a cured cement shape, wherein the cured cement shape comprises cement; a polymer layer adhered to the cured cement shape, wherein the polymer layer comprises a polymer comprising a liquid crystal elastomer; a suffused zone, wherein the suffused zone comprises the polymer of the polymer layer suffused into the cement of the cured cement shape; and a geometric shape that comprises a schwarzite structure. 2. The structural element of claim 1 , wherein the structural element has controlled mechanical failure characteristics. 3. The structural element of claim 1 , wherein the polymer layer has a uniform thickness between 10 and 1,000 micrometers.
