Wood-fibers were modified by silanes treatments and/or by coating with
polypropylene or polystyrene. Enhancement in thermal stability of woo
d fibers treated with gamma-aminopropyl triethoxy silane and in fibers
coated with polypropylene or polystyrene are discussed. Thermoanalyti
cal data (TGA, TMA and DSC) of the samples may aid to predict the beha
viour of these modified fibers in composites of polypropylene or polys
tyrene matrices. (C) 1998 Elsevier Science Ltd. All rights reserved.
