Flexural strength longitudinal 440 / 500 N/mm²
Flexural strength transversal 200 / 300 N/mm²
Flexural modulus of elasticity longitudinal 17500 / 25000 N/mm²
Flexural modulus of elasticity transversal 12000/ 17000 N/mm²
Compression strength transversal 240 / 350 N/mm²
Tensile strength longitudinal 430 / 900 N/mm²
Tensile strength transversal 60 / 200 N/mm²
Elongation at break longitudinal 2,2 %
Elongation at break transversal 1,6 %
Coefficient of expansion   1,5-5 x 10^-6xK^-1
Water absorption   1,16 / 2,5 %
