Abstract
One of the key issues in compression molding of natural fibre reinforced polymer (NFRP) bio-composites is the thermochemical degradation of the fibre and matrix during manufacture. In our previous work, models of thermal penetration, melt infusion, thermal degradation and chemical degradation of flax/PLA bio-composite were used to propose the degradation boundaries for bio-composite manufacturing. This study proposes a thermal degradation model which accounts for effect of time-dependent process temperature variation during manufacture of green composites. Kinetic data are used to calculate degradation progress parameters, defining experiment process maps for identifying the effect of the temperature history on the degradation progress and effects on the tensile strength. The model also can express the tensile strength changes in comparison with other degradation parameters.
