Impact Resistance of “Liquid Wood”

Abstract:

The main substances with an important effect over any company development are the materials which require simple or complex manufacturing processes. In the near future the using of recyclable materials will become an extremely important factor in all of activity fields. Therefore, liquid wood, due to its biodegradability and mechanical properties superior to other plastics, could replace some plastic materials soon. In case of arboform the granules made from: lignocellulosic fibers (combination of cellulose, lignin and wood polyoses); natural Polymers: lignin, polyester; natural resins/waxes: aliphatic and aromatic ketones, alcohols, carbonic acids, lactones and polycycles in monomeric, oligomeric and polymeric form. In case of arbofill it made from petrochemical polymers like polypropylene or polyethylene, reinforced with natural fibres like hemp, flax or wood. The arboblend contains different biopolymers like e.g. polyhydroxialkanoate, polyester, ingeo TM, lignin, starch, cellulose, organic additives, natural resins or waxes and natural reinforcing fibers, [. Because the injection process of arboform L, V3 Nature was very difficult this material was reinforced with 5% aramid fibers. The properties of liquid wood are very important to be known take into account the possibility to find some plastic materials for replacing. Therefore the paper presents some aspects of research concerning the impact resistance of these materials. For that was used the injection process to obtain the samples with six input parameters inside of experimental plan. Each factor had two level and was used the Taguchi methodology. The results obtained and the plastic materials that could be replaced are as follow: arbofill Fichte: (11-15) kJ/mp and it could be replace the PC GF 30, PPE GF 30, PEEK GF 30 (Poly Ether Ether Ketone Glass Filled), PEEK CF 30 (Poly Ether Ether Ketone Carbon Filled), PEI GF 30 (Poly Ether Imide); arboblend V2 Nature: (20-26) kJ/mp and it could be replace the PA 66 GF 30, PA 11 GF 30, PC GF 30, PP GF 30, PMMA, PPE GF 30, PEEK GF 30 (Poly Ether Ether Ketone Glass Filled), PEEK CF 30 (Poly Ether Ether Ketone Carbon Filled), PEI GF 30 (Poly Ether Imide) and arboform L, V3 Nature reinforced with aramid fibers: (8-14) kJ/mp and it could be replace the PC GF 30 (30% glass fiber), PVC, PPE GF 30, PEEK GF 30 (Poly Ether Ether Ketone Glass Filled), PEEK CF 30 (Poly Ether Ether Ketone Carbon Filled), PEI GF 30 (Poly Ether Imide).
