Influence of some parameters on the warping of the sawn wood of Pinus caribaea Morelet, var. Caribaea
The aim of this paper is to describe the influence of the fibre inclination and the width of the growth rings on the deformations (warping), in the radial direction of the sawn wood (post drying) of Pinus caribaea Morelet, var. caribaea. One hundred sawn wood pieces were taken from three positions i...

| description | The aim of this paper is to describe the influence of the fibre inclination and the width of the growth rings on the deformations (warping), in the radial direction of the sawn wood (post drying) of Pinus caribaea Morelet, var. caribaea. One hundred sawn wood pieces were taken from three positions in the log, at different distances from the pith in the radial direction, coded as A (12 cm), B (24 cm) and C (36 cm). To measure the width of the growing rings, a callipers was used, taking a referential position in the horizontal direction. The inclination of the fibre was measured using a pointed piece and a tape measure and the length of the sides was determined: the opposite cathetus and the hypotenuse of the triangle formed and applying the expression the studied angle was determined. As a result, it was obtained that the inclination of the fibre, the width of the growth rings and warping decrease towards the bark. The correlation coefficient between warping and fibre inclination is 0.372 and between warping and ring width is r = 0.859. |
