| dc.description.abstract | Sisal natural fiber - recycled pet bio composite is a composite material produced from sisal fiber and polyethylene Tere Phthalate (PET) injection pressing and by using hot pressing. The recycled pet has been utilized as the matrix and the natural sisal fiber acts as reinforcement in the course of the production of the composite material. The composite material has been made for the house ceiling application. In the investigation the physical properties and optimization the process parameters of the bio composite synthesized from recycled Polyethylene Tere Phatalate (pet) and Agave Sisalina (sisal) plant fiber for house celling applications, the ratio of the fiber and the pet were15/85, 25/75and 35/65 and Press times for all sample taken 10 minutes. The sisal fiber treated with 10, 15, 20 % alkali solution with treatment time 24, 48 and 72 hours. The effects of treatment time, sisal to pet ratio and concentration of alkali on internal bonding and flexural bending were investigated by using a full factorial design using Design Expert 7.0.0 and determined the optimal value. Characterization of the physiochemical properties of the bio composite was analyzed and the results obtained from experiments that internal bonding 1.36N/mm 2, flexural strength 520 N/mm 2 and the fiber has been characterized as 0.75% cuticle, 8% dry matter, 13.1 % moisture content, density of the fiber 1.33g/m , tensile strength 600-700 Mpa, yongus modulus 10.40 GPa, elongation of 2-3 % and 0.9 % ash content. 3 The obtained products were tested for their physical and mechanical properties such as density, internal bonding (IB) according to German DIN 52352 Standard and flexural bending test. The results indicated that all properties of test were coinciding with wood related particleboards. The optimal value of the internal bonding strength and flexural bending strength of the composite at sisal to pet composition ratio of 25/75 in %, treatment time at 72hr , alkali concentration 20% and plate temperature of 246 respectively. | en_US |
