Prediction of Thermal Conductivity of Bamboo Fiber/Polypropylene Nonwovens in Thermal and Mechanical Properties of BF/PP Composites Based on Regression Analysis
Bamboo fiber reinforced polypropylene(PP)nonwovens and composites were prepared by incorporation of different mass fractions of bamboo fibers.The effect of bamboo mass fractions on the thermal conductivity and mechanical properties of the bamboo fiber/polypropylene(BF/PP)nonwovens and composites were investigated.The relationship between thermal conductivity of BF/PP needle punched nonwovens as well as thermal conductivity and mechanical properties of composites was studied.The results show that the breaking strength of transverse and longitudinal oriented nonwovens decreased with the increase of bamboo fiber contents whereas the inverse trend was observed with respect to gas permeability.The thermal conductivity of BF/PP felt was found to be the best with a mass fraction of bamboo fiber of 60wt%.At 70wt%mass fraction of bamboo fiber both the mechanical properties and thermal conductivity of BF/PP felt were found to be excellent.The Shear strength and thermal conductivity of the composites increased linearly with the thermal conductivity of nonwovens.The thermal conductivity of the nonwovens had a quadratic polynomial relationship with the composites tensile and flexural strengths.
