Biofabrics are derived from living organisms such as seaweed or bacteria and have been proposed as sustainable alternatives to conventional fabrics such as cotton or polyester. But how do these materials perform when it comes to their mechanical properties, such as strength? This video will show how you can conduct two materials tests (tension test and torsion tests) at home. How will your material perform? Complete written instructions, including more background information about biofabrics,…
