• Composite laminate
• High-density polyethylene
• Stiffness
• Water supply pipelines

To increase the overall stiffness of a composite laminate is usual to use a polyester mat embedded as core in thin structures. This procedure can increase the structure's stiffness without increasing the thickness of a laminate.The paper presents the most important results obtained during three and four-point bend tests carried out on 20 x 2 mm, 25 x 2 mm, 40 x 2.3 mm, 63 x 4 mm and 90 x 6 mm high-density polyethylene (HDPE) pipelines used for water supply networks. In three-point bend tests the Young's modulus of bending decreases with the increase of pipelines' diameter. Main mechanical properties such Young's moduli of bending, flexural rigidity, stiffness, load/deflection at maximum deflection and load have been determined.
