Abstract

The current trend in the construction industry is the effort to achieve sustainable
development using rapidly renewable materials instead of limited ones. Need
for the development of environmentally friendly products is related to the industrial
interest in the use of natural plant fibres as reinforcement in composites.
The attention is given to hemp fibres as a substitute for synthetic fibres
due to their unique mechanical, thermal insulation, acoustic and antiseptic properties.
Key problem for successful application of hemp hurds as reinforcement into
composites is its high moisture sorption and its heterogeneity what lead to low
cohesion of fibres to the matrix. Optimizing the adhesion of plant fibre to inorganic
matrix is related to the modification of hemp surface. The objective
of this paper is comparison of changes in FTIR spectras caused by combination
of physical and chemical modification of hemp material with unmodified sample.
Modification of hemp hurds was carried out by ultrasonic treatment
and as the cleaning medium were used deionized water and NaOH solution.
