In this research, the effects of liquefied tropical wood (LTW) as reinforcing fillers
in the thermoplastic polymer composite on the mechanical and physical properties were
investigated. The LTW were prepared from tropical softwood species by using phenol as a
reagent and sulphuric acid as a catalyst. Polypropylene (PP) as polymer matrix was used with
LTW to made LTW/PP composites. The composites were prepared with 10, 20, 30, and
40wt.% LTW using the hot-compression molding method. The effect of LTW on physico-
mechanical properties of LTW/PP composites were evaluated using tensile test, three point
bending test and water absorption test. It was found that the flexural modulus of elasticity
(MOE) and Young.s modulus (E) increased due to the addition of LTW in the composites. In
addition, the water absorption and thickness swelling coefficient increased with the LTW
loadings.
