Madison, WI, U.S.A., 23-25 Mayo 2005 (poster) The purpose of the work has been to formulate and study new composites using fillers and resins obtained from renewable resources combining low cost and good mechanical properties. Two examples will be presented: a composite made from a polyester type resin crosslinked with styrene and reinforced with pine woodflour and, a reinforced rigid polyurethane foam made from hydroxylated linseed oil and MDI prepolymer with the addition of woodflour. The relationship between filler content, porosity fractions and mechanical properties of materials prepared from the linseed oil resin/styrene copolymers and woodflour was investigated. The foams were tested to evaluate density, thermal conductivity and compression behavior.
