Full Article Fillers for Papermaking: A Review of their Properties Usage Practices and their Mechanistic Role Martin A Hubbe * a and Robert A Gill b Issues of cost and product quality have caused papermakers to place increased attention on the use of mineral additives which are the subject of this review article
In this study composite nanofibres were fabricated from solvent fractionated softwood kraft lignin (SKL) NCC and polyethylene oxide (PEO) by electrospinning The molecular organization of lignin was investigated in the form of spun fibres and films with and without NCC Subsequently the as-spun composite nanofibre mats were thermally stabilized in the air under controlled conditions The

The effect of fiber loading and concentration of alkali treatment on mechanical properties of the composites were investigated The results showed that the tensile properties of composites with successive treated fiber at higher fibre loading were better than those of composites with untreated fiber The composite with successively treated jute fibre at 10% NaOH and H
Optical fibre sensors (OFS) as a result of their unique properties such as small size no interference with electromagnetic radiation high sensitivity and the ability to design multiplexed or distributed sensing systems have found applications ranging from structural health monitoring to biomedical and point of care instrumentation While
The project consists in the implementation of a biocomposite based on tannin resin and natural rubber matrices with the bast fibres of Triumfetta cordifolia A Rich "Okong" from the equatorial region of Cameroon as reinforcement A study of this still little known fibre is necessary This paper evaluates the physico-chemical and mechanical characteristics of the fibers
The thermal stability of the composite had been reduced with successive alkali treatments as evident from the TGA analysis The percentage weight loss in all the composites was linearly increasing with number of days of soil burial The degradation was high in composite with untreated fibers at highest weight fraction Using enzymatic environment the degradation was much faster compared to

The basalt fiber-reinforced polymer (epoxy resin) which has even better mechanical properties than glass fiber-reinforced polymer is a good choice for making FML (fiber-metal laminate) composite Herein drop-weight impact tests of basalt fiber-based FMLs (called BFMLs) were conducted in the INSTON 9520HV testing machine to investigate the low-velocity impact properties of BFMLs
The effect of alkali addition in oxygen delignification on Kappa No of pulp and brightness is shown in Fig 3 Kappa No of the pulp reduced sharply with 2% alkali and then steadily upto 5% alkali The brightness of the pulp improved moderately which is caused by delignification and not by lignin bleaching The effect of alkali/oxygen delignification on pulp shrinkage (%) is represented in
In the present work a novel physical treatment (PLA coating) of sisal fibres and its influence on the water absorption static and dynamic mechanical properties of its composites has been presented The treated sisal fibres were used consisted of alkali treatment and PLA coating to fabricate its polyester-based composites by hand lay-up technique keeping constant fibres content as 20 wt
Stress relaxation curve of PALFiLDPE composites at different fibre loading (Successive graphs are displaced upward by 0 05 for clarity strain level 4% fibre length 6 mm) Stress relaxation is greatly reduced by the addition of fibres to the matrix particularly in the initial period (Figure 7 3) The rates of relaxation for the composites are provided in Table 7 2 It is seen that in all
29 12 2015Flame Retardant Applications Synthetic fibers such as polyamide or polyester are highly inflammable and continuous investigations are carried out in the development of flame retardant products because the legislation requires the use of low flammability products in the industry [] In this context many of the available systems for flame retardancy are composed of halogen-containing additives
6 4 Conclusion Alkali and silane treatments were carried out to improve the physical and mechanical properties of sisal fibre with the intent to improve the properties of composites the fibre is constituent in It was observed from experimental findings that the adoption of chemical treatments enhances single fibre bundle tensile properties This was due to the removal of impurities and
Treatments of Cellulose Industries of all kinds- food processing forest products and pulp and paper face major problems with disposal of wastes derived from plant material Cellulose comprises nearly half the dry weight of most plant material Carbon fiber has been described as a fiber containing at least 90 carbon obtained by the controlled pyrolysis of appropriate fibers The Term
The effect of alkali and acid treatment of the fibre surface was studied by XRD XRD analysis of the alkali treated fibres also revealed an increase in the crystallinity index of the banana PALF and jute Other researchers have noted an improvement in the order of the crystallites as the cell wall thickens upon alkali treatment ( Mwaikambo Ansell 1999 ) The crystallinity index initially
14 03 2019In this study our aim is to analyze the influence of fibre treatments and different fibre loading on mechanical physical and chemical properties of pineapple leaf fibre reinforced polyester composites (PALF/PE) Fibre treatments were carried out with 1 N NaOH and KOH for 1 h The untreated and treated PALF/PE composites were fabricated with 25 wt% 35 wt% and 45 wt% fibre loadings by
Accelerated weathering and soil burial tests on biocomposites of various ratios of coir (CF)/pineapple leaf fibres (PALF) with polylactic acid (PLA) were conducted to study the biodegradability colour and texture properties as compared with PLA The biodegradability of a lignocellulosic composite largely depends on its polymer matrix and the rate of biodegradation depends on many
