Crystallization kinetics of pineapple leaf fiber reinforced phenol formaldehyde composites

Abstract

<span style="font-size: 15.0pt;mso-bidi-font-size:8.0pt;font-family:" times="" new="" roman","serif""="">Kinetics of crystallization in pineapple leaf fiber rein forced phenol formaldehyde (PF) composites has been studied employing

<span style="font-size: 15.0pt;mso-bidi-font-size:8.0pt;font-family:" times="" new="" roman","serif""="">Differential Scanning Calorimetry (DSC). Kinetic parameters such as activation energy in crystallization as well as in glass transition

<span style="font-size: 15.0pt;mso-bidi-font-size:8.0pt;font-family:" times="" new="" roman","serif""="">region have been investigated at different percentage of fiber (typically at 15, 20, 30, 40 and 50% by weight) and at different heating rate (typically at 5, 10, 15, 20 <i><span style="font-size:15.5pt;mso-bidi-font-size:8.5pt; font-family:" times="" new="" roman","serif""="">K/m</span></i><span style="font-size: 15.0pt;mso-bidi-font-size:8.0pt;font-family:" times="" new="" roman","serif""="">in). The obtained data has been analyzed in terms of modified Kissinger equation and also using Matusita's equation to determine the activation energy. The results from one model are compared with the value obtained from the other equation. It is found that, activation energy depends upon the fiber percentage whereas it shows a weak dependence on heating
