Ipe

  • Tabebuia spp
  • English: Ipe, Lapacho
  • Central America and south America.

Description

&;8226; Sapwood: yellowish white colour.
&;8226; Heartwood: dark grey with a very characteristic greenish shade.
&;8226; Fiber: straight, usually intertwined or very intertwined.
&;8226; Grain: thin to medium size.

Applications

&;8226; Interior and exterior furniture and cabinet work.
&;8226; Interior carpentry, doors, stairs, paneling, molding, baseboard, friezes, parquet flooring.
&;8226; Exterior carpentry, doors and windows.
&;8226; Interior and exterior carpentry.
&;8226; Decorative panels.

Capacity of being impregnated

&;8226; Sapwood: medium capacity of being impregnated.
&;8226; Heartwood: low capacity of being impregnated.

Mechanization

&;8226; Sawing process: ordinary problems due to hardness. Fast blunting.
&;8226; Drying process: Slow. Little risk of deformation and crack formation.
&;8226; Planing process: Difficult due to its hardness and high risk of repelling. Slow mechanisation is recommended.
&;8226; Gluing process: tannins hamper proper adherence.
&;8226; Nailing and screwing process: pre-drilling is recommended due to hardness.
&;8226; Finish: rubber deposits can locally hamper varnish adherence.

Physical properties

&;8226; Apparent density at 12% humidity 1.050 kg/m3 very heavy wood.
&;8226; Dimensional stability
- Volumetric contraction coefficient 0.41 % stable wood.
- Relation between contractions 1.27% no tendency to deformity.
&;8226; Hardness (Chaláis-Meudon) 8.5 very hard wood.

Mechanical properties

&;8226; Resistance to static flexion 1,750 kg/cm2.
&;8226; Elasticity module 200,000 kg/cm2.
&;8226; Resistance to compression 890 kg/cm2.

Observations

&;8226; It is currently a very popular sort of wood with much demand and very little supply.
&;8226; It can be substituted by a large number of other species.
