Stratimat300 glass fibers with 300 g/m 2 specific weight has been used to reinforce Heliopol 9431ATYX_LSE resin in hand lay-up process. A 6 mm thick composite laminate plate with five layers has been cured from which nine specimens have been cut using a diamond powder mill being under protection of a specific cooling system. Following main data have been recorded during three-point bend tests: Stiffness (N/m), Young's Modulus of Bending (MPa), Flexural Rigidity (Nm 2), Load at Maximum Load (kN), Deflection at Maximum Load (mm), Load at Maximum Deflection (kN), Deflection at Maximum Deflection (mm), Load at Break (kN), Deflection at Break (mm). Additional experimental data including twelve interesting mechanical properties have been also determined during three-point bend tests.
