PRODUCT INFORMATION

Fibreglass-reinforced polyester profiles are produced by pultrusion. Pultrusion is a continuous process during which a thermosetting polymer and reinforcement fibres are moulded into a profile.

the-pultrusion-process

Fibreglass-reinforced polyester profiles are produced by pultrusion. Pultrusion is a continuous process during which a thermosetting polymer and reinforcement fibres are moulded into a profile. Reinforcement materials such as fibreglass rovings and mats are drawn through a liquid resin bath where they are impregnated with the resin. The impregnated material is then formed to the desired shape and pulled trough a heated die.

It is in this die that polymerisation or curing occurs.It is in this die that polymerisation or curing occurs.

The product is then passed through the die by the puller gripper mechanism and cut by a saw to the required length.

THE EUROPEAN STANDARD FOR PULTRUSION PROFILES

Pultruded profiles are non isotropic materials. Therefore, a European system of standards was developed to achieve clear standards and usable values for designs. At present, manufacturers of good quality products are only producing structural profiles that meet this European standard: EN 13706.

This standard defines the minimum quality requirements and specifies the technical properties and values for use in calculations for 2 quality categories: the E23 series with a bending modulus of 23 GPa and the E17 series with a bending modulus of 17 GPa. Utilo profiles fall into the E23 class.

A European standard has also been drawn up for the design of access structures: the EN 14122. Additionally, the Eurocomp design guide’ has been drawn up and it sets design criteria for the safe design of structures made of fibreglass-reinforced plastics. DIN 18820 states specific design criteria for structures used in corrosive chemical environments.
