Effect of lay-up angle on mechanical properties of composites based on rib knit jute preforms

Abstract

263-266<span style="font-size: 16.0pt;font-family:Fd839219-Identity-H;mso-bidi-font-family:Fd839219-Identity-H">The mechanical properties of knitted jute reinforced composites with different stacking sequences have been studied. Flat rib knitted preforms have been produced in manual flat bed knitting machine followed by composite laminate preparation using simple hand Jay-up technique. It is observed that the mechanical properties are dependent upon the stacking sequence. <span style="font-size: 16.0pt;font-family:Fd839219-Identity-H;mso-bidi-font-family:Fd839219-Identity-H">The improvement in course-wise mechanical properties of the laminates has been observed with [0°/±45°/0°] and [0°/90°/90°/0°] lay-up sequences compared to [0°)4 lay-up sequence which shows improvement in properties in wale-wise direction. </span
