title: Improvement of mechanical performance of industrial hemp fibre reinforced polylactide biocomposites

authors: Sawpan, Moyeenuddin Ahmad

subjects: polymer–matrix composites

abstract: In this work, mechanical properties of chemically treated random short fibre and aligned long hemp fibre reinforced PLA composites were investigated over a range of fibre content (0–40 wt.%). It was found that tensile strength, Young’s modulus and impact strength of short hemp fibre reinforced PLA composites increased with increased fibre content. Alkali and silane fibre treatments were found to improve tensile and impact properties which appears to be due to good fibre/matrix adhesion and increased matrix crystallinity. A 30 wt.% alkali treated fibre reinforced PLA composite (PLA/ALK) with a tensile strength of 75.5 MPa, Young’s modulus of 8.18 GPa and impact strength of 2.64 kJ/m2 was found to be the best. However, plane-strain fracture toughness and strain energy release rate decreased with increased fibre content. The mechanical properties of the PLA/ALK composites were increased further due to alignment of long fibres.

title: Kia mau ki te aka matua: Researching Māori development and learning

authors: Hohepa, Margie Kahukura

abstract: The article involves a search for what might be useful, relevant and appropriate research framework for Māori for the study of Māori development and learning. It is also an attempt to articulate psychological approaches that will validate indigenous cultural epistemologies that support indigenous movements towards self-determination and that also provide useful tools for examining development and learning.
