Technical purpose EJ composites access covers are fibre-reinforced polymer material, providing high strength, light weight solution for pedestrian and vehicular traffic areas. Size of the representative product for LCA is 300x300 mm. The product complies fully with the standard EN124:2015. For more information: https://www.igbc.ie/wp-content/uploads/2024/06/EPDIE-23-123-Composite-Access-Cover-IE-EJ-20290613.pdf The manufacturing process begins with the design of the composite access cover according
to client specifications. Then, the moulding of the access cover begins with the lay-up process. Fiberglass mats are cut to the required size and layered into the mould. The arrangement
of fibres and the number of layers impact the strength and stiffness of the final composite. Thermosetting resin is injected into the layers of reinforcing fibres. The resin saturates the
fibres, creating a composite material when cured. The layered fibres and resin are subjected
to a high internal mould pressure to remove air bubbles and ensure proper impregnation
of the fibres with the resin. This step helps achieve a consistent and void-free composite.
The composite material is allowed to cure, a process which involves a chemical reaction
and cross linking of the resin that creates a strong and rigid matrix, bonding the reinforcing
fibres together. Once the composite has cured, the access cover is demoulded and undergoes
a quality control inspection. The completed composite access cover is packaged for
transportation in a wooden pallet, covered in shrink wrap and secured with plastic banding. |
