INTRODUCTION Today, development of materials technology using biomass is expected for creation of a sustainable society. Especially, the composite consisting of plant-based natural fibers and biodegradable resin, so-called the fully-green composites, is much expected for practical use. So far, we made textile green composites using biodegradable resin and plain woven ramie fabric and explored t...

Flat hourglass specimens are proposed to assess the compressive behaviour of FRP utilizing two testing techniques. The shape helped ensure failure at centre specimen and minimize in-plane stress concentration in this zone. Four-point bending tests carried out measures performed via DIC. A procedure calculate moment is validated presence large displacements. To evaluate method proposed, differen...
