BACKGROUND OF THE INVENTION 0002 The present invention relates to wood that is rein forced with a fiber-reinforced thermoset composite rods. Thermosets remain amorphous, although, above Tg, the liquid state goes from a freely flowing state for the uncured material to a rubbery state for the cured thermoset. To this end, innovative methods such as a thermoplastic hybrid interlayer and a thermoplastic film co-cure have been proposed [10], [12], [13]. While most elastomers are thermosets, thermoplastics are in contrast relatively easy to use in. The results show that PS resins can be crosslinked to form thermosets at temperatures less than 260°C.
