ABSTRACT

Plant fibers from wood and agricultural crops like flax and hemp are renewable
materials those have a potential for creating "green" products and replacing fossil
hydrocarbon materials harmful for the environment. Industrial hemp (Cannabis Sativa)
is an extraordinary non-toxic, non-narcotic plant and has been used for a wide variety of
applications. Hemp contains cellulose fibers and a woody material called shives. In
Europe, hemp shives and fibers are increasingly being used in a range of products like
textiles, paper and building materials. In this paper are presented the results of
experimental study of water absorption test conducted by immersing hemp composites
as well as original hemp shives in a de-ionised water bath during different time
durations. Physico-mechanical and physico-chemical properties of composites were
evaluated and compared with original dry composite specimens.
