thermal and crystallization studies of short Flax fibre reinforced polypropylene matrix composites effect of treatments
Thermochimica Acta, 2006Co-Authors: A Arbelaiz, Beatriz Fernandez, Jose Ramos, I MondragonAbstract:Abstract The effect of fibre treatments on thermal stability of Flax fibre and crystallization of Flax fibre/polypropylene composites was investigated. For thermal stability study, Flax fibres have been treated using maleic anhydride, maleic anhydride polypropylene copolymer, vinyltrimethoxy silane and alkalization. In order to compare thermal stability of Flax fibres thermogravimetry (TG) analysis has been used. Kinetic parameters have been determined by Kissinger method. Results showed that all treatments improved thermal stability of Flax fibres. For crystallinity analysis, three different techniques have been used, differential scanning calorimetry analysis (DSC), pressure–volume–temperature (PVT) measurements for analysis of volume shrinkage and polarized optical microscopy (POM). All techniques results showed that addition of Flax fibre increased crystallization rate. Besides, depending on fibre surface treatment and crystallization temperature, Flax fibre/PP composites can show transcrystallinity.

abaca fibre reinforced pp composites and comparison with jute and Flax fibre pp composites
Express Polymer Letters, 2007Co-Authors: Andrzej K Bledzki, Abdullah Al Mamun, Omar FarukAbstract:Abaca fibre reinforced PP composites were fabricated with different fibre loadings (20, 30, 40, 50 wt% and in some cases 35 and 45 wt%). Flax and jute fibre reinforced PP composites were also fabricated with 30 wt% fibre loading. The mechanical properties, odour emission and structure properties were investigated for those composites. Tensile, flex- ural and Charpy impact strengths were found to increase for fibre loadings up to 40 wt% and then decreased. Falling weight impact tests were also carried out and the same tendency was observed. Owing to the addition of coupling agent (maleated polypropylene -MAH-PP), the tensile, flexural and falling weight impact properties were found to increase in between 30 to 80% for different fibre loadings. When comparing jute and Flax fibre composites with abaca fibre composites, jute fibre composites provided best tensile properties but abaca fibre polypropylene composites were shown to provide best notch Charpy and falling weight impact properties. Odours released by Flax fibre composites were smaller than jute and abaca fibre composites.

effect of different knitted structure on the mechanical properties and damage behavior of Flax pla poly lactic acid double covered uncommingled yarn composites
Composites Part B-engineering, 2012Co-Authors: Gobi T Kannan, Chang-mou Wu, Kuo Bing ChengAbstract:Abstract Double faced plain and rib knitted fabric (DFPKF & DFRKF) were produced by using double covered uncommingled yarn (DCUY), where the Flax fiber is used as reinforcement and PLA (Poly Lactic acid) as matrix. DCUY was fabricated by the hollow spindle spinning machine with a Flax core yarn, which were wrapped around PLA sheath yarns. DFPKF & DFRKF fabrics were produced by flat knitted machine. Composites were fabricated with film stacking technique by hot pressing machine from DFPKF & DFRKF. Flexure and Izod impact test were carried out for DFPKF & DFRKF reinforced composites. Fractography examination was done by digital camera. The influence of different knitted structures on the mechanical properties of the composites is demonstrated in this research work.
