Abstract text:
Glass fibre reinforced polyester (GFRP) composite plate components fabricated by pultrusion are increasingly being used in civil infrastructure applications. Structural members made of GFRP composites are often constructed from plate like pultruded shapes. Verification of serviceability limit states requires good knowledge of stiffness properties, in particular along the principal axes of the material. The paper analyses the main stiffness characteristics, the available analytical formulas to evaluate them and experimental verification of the calculated values for a plate composite product fabricated by pultrusion.
Key Words:
glass fibres; polyester resins; pultrusion; elastic moduli.
