TLDR
In this paper, the use of enzymes, chelators and enzyme/chelator systems was explored as an environmentally friendly means of improving the quality of flax fiber for composite applications, and a commercial pectinolytic enzyme preparation and Ethylene Diamine Tetraacetic Acid (EDTA) were used separately and in combination on a commercial flax fibre.Abstract:
The use of enzymes, chelators and enzyme/chelator systems was explored as an environmentally friendly means of improving the quality of flax fibre for composite applications. A commercial pectinolytic enzyme preparation and Ethylene Diamine Tetraacetic Acid (EDTA) were used separately and in combination on a commercial flax fibre. An improvement in fibre cleanliness and separation of the fibre bundles into ultimates was observed. When this fibre was, subsequently, used as reinforcement in an epoxy matrix, improved composite properties were obtained. With the EDTA modified fibre reinforced composites, tensile strength improvements in excess of 50% were recorded.read more

Introduction To Composite Materials
TL;DR: The combination of materials to form a new material system with enhanced material properties is a well documented historical fact as discussed by the authors, which is why many artisans from the Mediterranean and Far East used a form of composite technology in molding art works which were fabricated by layering cut paper in various sizes for producing desired shapes and contours.

Analysis of the flax fibres tensile behaviour and analysis of the tensile stiffness increase
TL;DR: In this paper, the Young's modulus of a flax fiber is estimated by taking into account the composition of the fibre and the evolution of the orientation of the fibrils during a tensile test.

Properties and modification methods for vegetable fibers for natural fiber composites
TL;DR: In this paper, it is shown that modified cellulose fiber-polymer interaction mechanisms are complex and specific to every definite system, therefore, a surface modification of the fibers is necessary.

Influence of processing and chemical treatment of flax fibres on their composites
TL;DR: In this article, the influence of the flax processing parameters, and consequently of the fibre properties, on the mechanical properties of flax fibre reinforced epoxy composites was pointed out, and a treatment consisting of a combination of alkali and dilute epoxy gave the highest improvement of the flexural properties.
