Rice straw fibres have been extracted and incorporated i n polyester resin matrix to prepare rice straw reinforced polyester composites and the flexural properties of resultant composites studied. The composites with a mean flexural strength of 66.3 Mpa, which is greater than that of plain polyester (55 .08 M Pa), can be
bondability of straw with conventional resins. The study will help in efficient utilizing wheat and rice straw as an alternate resource for the industrial manufacture of particleboards and fibreboards.

Pigment & Resin Technology Performance of rice straw‐based composites using environmentally friendly polyalcoholic polymers‐based adhesive system in comparison with commercial thermosetting resin (urea‐formaldehyde), as well as the properties (mechanical and physical properties) of the composites produced
Sep 20, 2005 Sampling locations from a straw stem had significant influences on the tensile properties of rice straw. Generally, middle nodes of rice straw had the highest average tensile strength, which was followed by the bottom and top parts. Straw Panel Properties Panel density and resin level played a significant
the matrix may enhance the adhesion between the filler and polymeric resin . Irene S. et al.  investigated the mechanical treatment of rice straw fibres aiming to explore the available applications for a composite of low density polyethylene (LDPE) reinforced with rice straw (RS); by testing the mechanical properties at.
In the present work detailed study for the rice straw biocomposite is performed and a comparison of flexural strength is made between different biocomposites. Some of the composite, pure teak wood and plywood manufactured by different layers of (resin) and a reinforcement of natural fibres (usually derived from plants

Furthermore, the results showed that water hyacinths fibres presented a competitive reinforcement quality when they were compared with other natural fibers, as such jute, abaca, and rice straw.

of rice straw content, while the tensile strength slightly decreased, compared to pure PHBV resin. Differential scanning calorimetry (DSC) and thermogravimetry (TGA) results have demonstrated a minor effect of the rice straw on thermal behavior of PHBV resin. PHBV/RS composites are expected to be developed as
