The nonisothermal crystallization kinetics of modified bamboo fiber/polycaprolactone (MBF/PCL) composites was investigated by differential scanning calorimetry (DSC) at different cooling rates. The results were studied by a direct fitting of the experimental data to various macrokinetic models, namely, Avrami, Ozawa, and Mo models. Both the Avrami analysis modified by Jeziorny and the method developed by Mo could describe the nonoisothermal crystallization of the composites very well, but the Ozawa analysis could not give an adequate description. Kinetic parameters such as the Avrami exponent ( n ), the kinetic crystallization rate constant ( Z c ), the peak temperatures ( T peak ) and the half‐time of crystallization ( t 1/2 ) etc. were determined at various scanning rates. © 2010 Wiley Periodicals, Inc.
