title: Accelerated weathering of unbleached and bleached Kraft wood fibre reinforced polypropylene composites

authors: Beg, Mohammad Dalour Hossen

subjects: natural fibre composites

abstract: In this paper, combined moisture/ultraviolet (UV) weathering performance of unbleached and bleached Kraft wood fibre reinforced polypropylene (PP) composites was studied. Composites containing 40 wt% fibre with 3 wt% of a maleated polypropylene (MAPP) coupling agent were fabricated using extrusion followed by injection moulding. Composite mechanical properties were evaluated, before and after accelerated weathering for 1000 h, by tensile and impact testing. Differential scanning calorimetry (DSC), X-ray diffraction (XRD), thermogravimetric analysis (TGA) and scanning electron microscopy (SEM) were also carried out to assess the changes occurring during accelerated weathering. Bleached fibre composites initially showed higher tensile and impact strengths, as well as higher thermal stability and greater crystallinity. During accelerated weathering, both unbleached and bleached fibre composites reduced tensile strength (TS) and Young's modulus (YM), with the extent of the reduction found to be similar for both unbleached and bleached fibre composites. Evidence supported that the reduction of TS and YM was due to PP chain scission, degradation of lignin and reduced fibre–matrix interfacial bonding.

title: He tirohanga ki ngā iwi o Hauraki

authors: Ngāpō, Korohere

subjects: Kōrero nehe

abstract: Ahakoa kua kīia nei tekau mā rua ngā iwi o Hauraki i ēnei rangi, kua mōhiotia whānuitia e ngā tūnohunohu me ngā tohunga whakapapa o te kāinga e toru ngā tino nohonga tūturu ake o ngā iwi o Hauraki i mua i te tae putuputu mai o te iwi Pākehā. Ka mutu, he whakarāpopoto noa iho tēnei tuhinga ki ngā tūrangawaewae me ngā tapuwae o ngā iwi ki roto i ngā whaitua o Te Tara o Te Ika-a-Māui-tikitiki-a-Taranga. Ehara i te mea kua ruku hōhonu ake ahau ki ngā āhuatanga katoa o ngā whakapapa o Hauraki engari he paku makamaka tirotiro noa iho nā te rarahi, nā te whānui rawa o tēnei kaupapa. Mehemea ka tōminamina te tangata kia mōhio ai ki ngā hītori o Hauraki mokori anō tana whana atu ki ngā wāhi tapu, ki ngā kōrero tuku iho a ngā mātanga whakapapa.

Mehemea e tōminamina ana te tangata kia mōhio ai ko wai mā ngā tūpuna o Hauraki i ngā wā o mua, me hoki whakamuri ki ngā iwi tuatahi tae noa mai ki ngā iwi 12 e noho atu ana ki ngā ripa tauārai o Hauraki ā mohoa nei.
