Extrusion of five biopolymers reinforced with increasing wood flour concentration on a production machine, injection moulding and mechanical performance

摘要: On account of restricted availability petrochemical resources and increasing environmental concern this study is focused on extrusion injection moulding different biocomposites, containing up to 70% wood flour. Clear decreases in flow ability were assessed with rising fibre load. These inhibited blends more than 65% content. The tensile flexural strengths all biopolymers except for the polylactic acid (PLA) significantly improved. Huge increases also determined modulus elasticity, whereas impact performance water resistance dropped dramatically In general at higher filling levels lower impacts content mechanical properties observed.
