FUENTES-SALINAS, M.; CORREA-MENDEZ, F.; BORJA-DE LA ROSA, A.  e  CORONA-AMBRIZ, A.. Technical properties of sixteen types of woods from the state of Tamaulipas, which influence on the manufacture of particleboards and fiberboards. Rev. Chapingo ser. cienc. for. ambient [online]. 2008, vol.14, n.1, pp.65-71. ISSN 2007-4018.

In the following study four properties of sixteen different types of woods from the seasonally dry tropical forest were analyzed with the purpose of determining if they are useful in the manufacturing of particleboards and fiberboards. The woods analyzed were: Myrcianthes fragrans, Phoebe tampicensis, Casimiroa pringley, Acacia berlandieri, Drypetes lateriflora, Esenbeckia berlandieri, Lysiloma divaricata, Robinsella discolor, Sapindus saponaria, Harpalyce arborescens, Wimmeria concolor, Krugiodendrom ferreum, Ebanopsis ebano, Pithecellobium pallens, Zanthoxylum fagara y Cordia boissieri. The fiber's properties analyzed were the longitude, longitude-diameter relation known as Peteri coefficient, basic density, pH and the razon de compression which is neces-sary to manufacture medium density particleboards and hardboards. The fiber from the analyzed woods had a longitude rank of 653 to 1229 µ, a Peteri coefficient rank of 43.14 to 82.45, a pH rank of 5.06 to 7.64 and a basic density rank of 0.56 to 0.97 g·cm^-3. Due to this values and its analysis, eleven types of woods individually were considered useful for the manufacture of medium density particleboards. If the woods are mixed then twelve species can be useful for the manufacture. All types of woods can be used to manufacture hardboards and extra hardboards.
