In April 2016 Manchester eScholar was replaced by the University of Manchester’s new Research Information Management System, Pure. In the autumn the University’s research outputs will be available to search and browse via a new Research Portal. Until then the University’s full publication record can be accessed via a temporary portal and the old eScholar content is available to search and browse via this archive.

Abstract

The use of Raman spectroscopy as a tool to monitor the deformation micromechanics of flax fibre/poly(L-lactic acid) (PLLA) model composites is presented in this research work. It is shown that a stress profile can be obtained from the shift in the peak position of the Raman band initially located at 1095^-1 through a PLLA microdroplet on a flax fibre at elevated strain. These stress profiles micromechanics of the flax/PLLA composite are theoretically interpreted and fitted using a fourth order polynomial. The interfacial shear stress between the fibre and resin is then compared to values obtained using a microbond test.
