The composite materials were processed by employing hand lay-up and compression moulding methods and fibres were treated with NaOH solution. The composite samples were subjected to tensile, flexural and impact tests. Based on the findings, compression moulding method produced better mechanical properties compared to the composites manufactured by hand lay-up method. The results showed that the tensile strength and Young’s modulus of the samples produced by compression moulding method increased by 77 percent and 47 percent respectively (at optimal fibre loading) compared to those produced by the hand lay-up method. The results also showed noticeable improvements in the impact strength of the material produced by compression moulding method, with impact strength of 11.5 kJ/m2 against the samples produced by hand lay-up method, with impact strength of 7 kJ/m2.展开更多

The PRBAC reactor simply increased reactor pressure to create an enriched dissolved oxygen （DO） environment to stimulate the bioactivities of microbes on GAC surface for removing refractory organic matter. Rapid Small-Scaled Column Test （RSSCT） was carried out to evaluate the adsorption characteristics of target stream constituents, and over 80% COD components were poorly adsorbable while about 82.5% color inducing matter and 85% UV 254 surrogated matter were readily adsorbable. Compared with performances of normal BAC reactor under conventional DO condition, PRBAC achieved 20%, 10% and 50% more removal in COD, color and NH3-N abatement.展开更多
