Materials and Design, v. Thirteen specimens were used for each test, totalizing experimental results. Journal of the Korean Wood Science and Tecnology, v. It demonstrate the relation between these properties and the apparent density but unable to use them as an estimator of these properties due catenaeformls poor adjustment.

These large pores give it a unique open texture, with the pores appearing as thin dark veins on all facegrain surfaces. Thus, Cedrelinga catenaeformis Ducke appears catenaeforrmis a very interesting option, especially to Brazilian Amazonian Region, the west and southeast part of Brazilian country, where the occurrence of this wood specie is more noticeable [5].

Cerelinga fit obtained to estimate the strength values of wood by apparent density – geometric a and linear b models. Prices are moderate for an imported hardwood.


Conclusions The results of this study permit us to conclude: Arnaldo Uliana February catfnaeformis, at 7: Moreover, the use of ANOVA, which allows to accept or not the representativeness of the tested models, the coefficient of determination values R 2 were obtained as a way to evaluate the capability of the apparent density to explain the estimated dependent variable.

Cedrellnga properties results for the Cedrelinga catenaeformis Ducke wood. In this context, it seems important to search alternatives to reduce costs and, in this paper, it is intended to correlate all mechanical properties with density. European Journal of Wood and Wood Products, v.

A company located in Brazil https: Regression models for the stiffness values estimation of the Cedrelinga catenaeformis Ducke by the apparent density. Besides the standard health risks associated with any type of wood dust, no further health reactions have been associated with Tornillo.

It should be noted that 13 values for each one of its physical 3 and mechanical properties 12 were investigated, resulting in experimental values obtained. Physical properties results for the Cedrelinga catenaeformis Ducke wood. Mechanical and physical properties measured for the Cedrelinga catenaeformis Ducke wood specie.

Aiming to contribute to the use of new wood species in building construction, mainly in structural purposes, as well as other applications, this study intended to determine the physical and mechanical properties of Cedrelinga catenaeformis wood specie and evaluate the possibility of estimating strength and stiffness properties investigated by density.

The estimation of strength and stiffness properties by density via mathematical methods regression methods could enable the engineers a better pre-design of the structure.

Turns, glues, and finishes well. This turned possible to determine, among the considered significant models 4 models for each of the 12 strength properties and estimated stiffness — resulting in carenaeformis adjustmentsthe ones with the best fit. Cedreliga the apparent density of Cedrelinga catenaeformis 0. The mechanical properties of Cedrelinga catenaeformis obtained demonstrated compatible performance with regular wood species used in temporary civil construction.

Rated as moderately durable; poor insect resistance.

All stiffness properties met the values of the coefficients of variation required by the standard and all strength properties exceed the limit but hardness normal to the grain fH90 which attended the limit, showing a Cv equal to 0.

Save my name, cedrrelinga, and website in this browser for the next time I comment.

Results and Discussion 4. Full Characterization of Calycophyllum Multiflorum wood specie.

However, it is timely to register the high number of required tests, aspect that causes a high cost for wood characterization equipment and services. To use of wood rationally in a large range of possibilities, the knowledge of its anatomical, chemical, physical and mechanical properties is crucial.
