Title

Lapinus Fibre Reinforced Phenolic Composites: Flexural and Friction Properties

Abstract

The flexural and fnctional properties of Lapinus fibre-reinforced phenolic friction materials at different fibre loadings have been studied via threepoint bend tests and SAEJ661a friction tests, respectively. A positive correlation was observed between flexural moduli and fibre volume fraction for these materials. The empirical constant in the Halpin-Tsai model is about 0.22 for this material compared with 0.375 for some other fibre reinforced structural composites with randomly distributed fibres in a plane. The coefficient of friction of the composites fell in the range of 0.1 to 0.5 and the minimum friction was found in materials with volume fraction of 0.024 to 0.05 fibre loading. These two fibre loadings also showed a more stable coefficient of friction than the other fibre loadings did over the wide range of temperatures in the second fade test. A minimum volumetric wear was found in the material with 0.05 fibre loading during the wear test. The wear mechanisms at different fibre loadings have also been discussed.
