We synthesized cellulose/gypsum composites in the presence and absence of sodium alginate and investigated the interaction between the composite components as well as the mechanical properties of the final composites. Four different types of cellulose fiber materials were used: cellulose UFC100, cellulose B400, nanofibrillated cellulose, and Lyocell fiber. For all investigated composites the total amount of admixed cellulose was between 1 and 2 wt%, the amount of admixed sodium alginate was 0.5 wt%. We determined the morphology of the composites and observed that the particle and fiber dimensions of the admixed cellulose affect the mode of gypsum-gypsum interlocking and the total porosity of the composites. This in turn had a substantial influence on the mechanical properties of the final composite materials. The addition of sodium alginate resulted in an increase of ultimate strain values. Composites with Lyocell fiber, a synthetic fiber, also had a high Young's modulus.

Original scientific paper The aim of this study was to investigate the impact resistance and damage behaviour of gypsum and composite gypsum boards subjected to low velocity impact. Low velocity impact tests were performed on four different board materials which can be listed as gypsum boards, gypsum+75 gr/m² mesh boards, gypsum+wallpaper boards and gypsum+75 gr/m² mesh+wallpaper boards. Indenter used in the impact tests was 24 mm in diameter and has semi spherical tip geometry. Gypsum and composite gypsum boards were bonded in 500×400 mm sizes and simply supported at four sides. Various energy levels, i.e. 2, 4, 6, 8, 10 and 12 J were applied to the centre of each board. As a result of low speed impact tests, impact force-time and force-displacement variations were obtained and the damaged regions of the samples were examined. Penetration thresholds and perforation thresholds of gypsum and composite gypsum board samples were determined by using Energy Profile Method (EPM). The effect of adding mesh and wallpaper into the gypsum board on stab and puncture limits was evaluated. Around 62.40 % increase occurred on gypsum+mesh+wallpaper board comparing to gypsum board in perforation thresholds.

Ispitivanja udara male brzine provedenu su na četiri različita materijala ploča, i to gipsane ploče, gips+75 gr/m² mrežaste ploče, ploče od gipsa+zidna tapeta i ploče od gipsa+75 gr/m² mreže+tapeta. Udubljenje korišteno u udarnim ispitivanjima bilo je 24 mm u promjeru i geometrije polu kuglastog tipa. Gipsane i složene gipsane ploče bile su spojene u veličinama od 500×400 mm i jednostavno pridržavane na četiri strane. Na sredinu svake ploče djelovalo se energijom različitih razina: 2, 4, 6, 8, 10 i 12 J. Kao rezultat ispitivanja udara male brzine, dobivene su varijacije udarna sila-vrijeme i sila-pomak te su ispitivana oštećena područja uzoraka. Granice penetracije i granice perforacije uzoraka gipsanih i složenih gipsanih ploča određene su EPM metodom (Energy Profile Method). Procijenio se učinak dodavanja mreže i tapete u gipsanu ploču na granice izdržljivosti kod udaranja i probijanja. Na ploči od gipsa+mreža+tapeta došlo je do porasta granice perforacije od oko 62.40 % u usporedbi s gipsanom pločom.

“…In ceramic materials, fibre helps prevent the progression of cracks from their origin and also avoids the piece breaking completely in two 7,8 . Polypropylene has been used by many authors as a matrix phase in the study of composite materials, the fibres used in these studies were of different origin, natural and synthetic [9][10][11][12][13][14] .…”

SUMMARYThe importance of recovering waste materials generated by industrialised societies is mainly due to the environmental impact that they have, and one of the principal problems is the presence of end of life tyres. The use of waste microfibre obtained from shredded tyres as reinforcement in polypropylene matrices offers an interesting opportunity for recycling of the waste microfibre, in order to obtain 'value added products' from polypropylene (PP)/waste microfibre tyre composites. The microfibres obtained from shredded tyres were used as a reinforcing material in compositions with polypropylene (PP). The blending proportions were: (1) 10% microfibre 90% PP; (2) 20% microfibre, 80% PP; (3) 30% microfibre, 70% PP; (4) 40% microfibre, 60% PP, (5) 50% microfibre, 50% PP and (6) 80% microfibre, 20% PP. The mechanical and thermal properties were analyzed. In this case polypropylene mixed with polyamide (PA) microfibres show a decrease in tensile strength and elongation at break, however, impact strength and Vicat Softening temperature values increase with polyamide microfibre content. Continuity in the matrix phase was observed by scanning electron microscopy up to loadings of 40% microfibre.
