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 process for making a multi-material structural element having controlled mechanical failure characteristics, the process comprising the steps of: supplying a loaded projecting member and a soluble retaining member on the loaded projecting member, wherein the loaded projecting member comprises a polymer and is loaded with potential mechanical energy, and wherein the soluble retaining member is at least partially soluble in a cement slurry; contacting the soluble retaining member with a cement slurry such that the soluble retaining member is at least partially dissolved and the loaded projecting member is released and projects into the cement slurry to form a released projecting member; and curing the cement slurry such that a suffused zone is formed where the released projecting member contacts the cement slurry polymer to obtain the multi-material structural element having controlled mechanical failure characteristics. 2. The multi-material structural element of claim 1 , wherein the loaded projecting member comprises a polymer selected from the group consisting of polyvinyl alcohol, polyvinylpyrrolidone, polylactic acid, liquid crystal elastomer, and combinations of the same. 3. The multi-material structural element of claim 1 , wherein the soluble retaining member comprises an alkaline-sensitive polymer. 4. The multi-material structural element of claim 1 , wherein the soluble retaining member comprises a polymer selected from the group consisting of polyvinyl acetate, polyvinyl alcohol, polylactic acid, and combinations of the same. 5. The multi-material structural element of claim 1 , wherein the soluble retaining member comprises a water-sensitive polymer. 6. The multi-material structural element of claim 1 , wherein the soluble retaining member has a thickness that is between 1 micrometer and 20 centimeters.
