Canola Fiber as Reinforcement for Composites: Effect of Fiber Extraction and Processing Method on Fiber Properties, Nonwoven Manufacturing, and Composite Properties

Polymer Composites, EarlyView.
Comparison of canola fiber reinforced composites manufactured using water‐retted, field‐retted, and enzyme‐treated fibers. ABSTRACT Canola fibers obtained from discarded stalks through various processing methods, including water‐retting and field‐retting followed by mechanical decortication and enzymatic degradation, were utilized as discontinuous ...

Tensile deformation of a flax fiber

Procedia Engineering, 2009
AbstractIn this paper we investigate the tensile properties of a natural composite material: the flax fiber. The beginning of the stress-strain curve of a flax fiber upon tensile loading appears markedly non-linear. The hypothesis of a progressive alignment of the cellulose microfibrils with the tensile axis provides a quantitative explanation of this ...

Comparative Evaluation of Structure–Processing–Property Relationships in Flax, Hemp, and Cattail Discontinuous fiber Thermoset Composites

Polymer Composites, EarlyView.
Needle punching reorients fibers from in‐plane direction toward z‐direction of the web, resulting in mechanical interlocking of fibers and reduction in the nonwoven mat thickness. ABSTRACT Replacement of glass fiber mats, utilized in large and complex composite parts in the transportation industry, with natural fiber mats requires knowledge of natural ...
