The effects of CB on PP/clay were studied by varying CB content at 3, 5, and 7 percent hundred resin (phr). The composites were prepared by melt mixing using internal mixer at 222 °C, 83 rpm, and 10 minutes. PP-grafted-Maleic Anhydride (PP-g-MA) was used as a compatibilizer to facilitate dispersion of clay layers and CB particles on PP matrix. The effects of CB on thermal properties were analyzed from Differential Scanning Calorimetry (DSC) and Thermogravimetry Analysis (TGA) data. Meanwhile flammability properties was observed from burning rate that was confirmed by dispersion level from morphological analysis. The result showed that clay and CB enhanced the degree of crystallinity (Xc) of neat PP, with the highest Xc was achieved at 3 phr of CB. There was a negative correlation between Xc and Initial temperature decomposition (T5wt%) that attributed to thermal conductivity. Moreover, the addition of clay and CB changed dripping behavior of neat PP due to increment of melt viscosity and decreased burning rate because of dispersion of CB that might improve radical trap action.","PeriodicalId":14103,"journal":{"name":"International Journal of Materials Science and Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78644274","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is general agreement that SCC requires three conditions: first, the alloy must be susceptible, second, there must be a specific environment (water or seawater for aluminium alloys); and third, there must be a tensile stress. The susceptibility of the wrought aluminium alloys to SCC is related to many environmental (chemical), Metallurgical (Microstructural) and Mechanical factors. Crack initiation may start at some surface discontinuities, corrosion pits, or may be developed by intergranular corrosion or slip dissolution. This review describes the models of environmental - related crack propagation of aluminum alloys (7xxx) during the last few decades. Acknowledge on effects of different factors on the susceptibility to SCC permits to propose valuable mechanisms on crack advancement. The reliable mechanism of cracking gives a possibility to propose the optimum chemical composition and thermal treatment conditions resulting in microstructure the most suitable for real environmental condition and stress state.","PeriodicalId":14103,"journal":{"name":"International Journal of Materials Science and Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85710091","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Most commonly used materials to fabricate the cement boards are wood. Therefore, due to the depletion of wood resources, the potential of Oil Palm Empty Fruit Bunch Fibre (OPEFB) as wood replacement for cement boards production is explored in this study as one of the materials for sustainable retrofit building. The main obstacle for Empty Fruit Bunch (EFB) fibre cement composite manufacturing is the chemical incompatibility between fibre and cement, which inhibits cement setting and hardening. In this study, EFB fibre was then treated with 0.4%, 1% and 4% of NaOH for EFB-CB fabrication and chemical accelerator which is calcium chloride (CaCl2) was used at 0.1%, 0.2%, 0.3% and 4% based on cement weight. Physical and mechanical properties were observed in this study. The result indicated that the best percentage of NaOH is 1% as pre-treatment for the fibres, meanwhile minimum percentage of 0.3% and 0.4% CaCl2 should be consider as cement accelerator in board production. Other than that, the minimum requirements for physical and mechanical properties were met by EFB fibre treated with 4% NaOH with or without cement accelerators.","PeriodicalId":14103,"journal":{"name":"International Journal of Materials Science and Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85918614","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
