Biodegradable composites based on l-polylactide and jute fibres

Fiber association and network formation in PLA/lignocellulosic fiber composites

“…Aspect ratio and particle size proved to influence properties considerably and contrary to many claims published in the literature [15,[33][34][35][36][37][38][39][40][41] we found that interfacial adhesion is rather strong between PLA and lignocellulosic fibers. As a consequence, usually the fracture of the fibers is 4 the dominating micromechanical deformation process, which determines composite strength.…”

Impact and tensile properties of PLA/Cordenka and PLA/flax composites

“…The best improvements have been reached using jute fibres 8 [11] and kenaf fibres [9]. The Cordenka fibres in this work caused an increase in tensile 9 strength of 30%.…”

“…But PLA has become an important part of R&D in the recent years because 11 of the benefits listed above. Mechanical tests on natural fibre reinforced PLA have been 12 performed with different types of fibres like kenaf [9, 10], jute [11], flax [12] abaca 13 [13], hemp [7] and Cordenka rayon fibres [14]. MPa, a Young's modulus of 3.11 GPa and an impact strength of 16.13 kJ/m 2 was 15 measured for this material in a former publication [7].…”

“…A comparison of the rates of improvement 22 which can be reached using different types of fibres to reinforce PLA can be found in 23 table 2. 24 As jute reinforcement, the use of flax fibres leads to a decrease of impact strength [11]. 1 Kenaf can also improve the impact properties of PLA but a clear improvement can only 2 be reached by the use of aliphatic copolymers [10].…”

Sustainable biocomposites based on autohydrolysis of lignocellulosic substrates

“…The formulation of biodegradable composites is gaining interest owing to the dwindling fossil resources and to the increasingly strict environmental regulations [11][12][13][14][15][16][17]. The latest trend in this field is to develop new materials which are based on 100% renewable resources [18].…”
