Fibre-reinforced laminated parts

Allows demoulding without post-curing; achieving maximum thermal and mechanical performance requires a heating cycle. Define the reinforcement and laminate structure for the loads the part will carry.

Demoulding is possible after room-temperature curing. If the part needs the maximum thermal and mechanical properties in the data sheet, allow for post-curing and suitable heating equipment.

For a clear glass laminate, use fabric with a compatible treatment: clarity does not depend on the resin alone. On cured layers without peel ply, sand, clean and degrease before continuing.

Prepare and clean the substrate before laminating. The thixotropic version helps with vertical lay-up, but reinforcement thickness and distribution must suit the part.

Laminate on surfaces free from rust, grease and oil, above 10 °C. Organise quantities and working area so the mix is used before it gels.

Allows demoulding after room-temperature curing. If the part requires improved thermal and mechanical performance, allow equipment and time for the 60–80 °C post-cure specified for the system.

Plan a glass-fibre-reinforced laminate and a curing temperature of at least 15 °C. If adding pigments or fillers, assess their effect before manufacturing the part.

The choice depends on the part's use: for demanding mechanical, thermal or chemical performance, compare specific alternatives. Pigment does not make this a clear finishing resin.

Plan a post-cure for the best long-term water resistance. For a vessel subject to inspection, confirm construction requirements and the approval applicable to the project.

Thixotropy helps retain resin on sloping surfaces. Design the laminate and cure for the part: the thermal values in the data sheet are obtained with post-curing.

Test the intended laminate first. For optimum performance and long-term stability, allow a post-cure cycle adapted to thickness and service temperature.

Its reactivity is designed for colder working periods. If the final layer is exposed to air, allow for a suitable additive, such as a paraffin solution, to obtain a tack-free surface.

A blend of batches from different polyester families. Reserve it for work without specific structural or chemical requirements and assess the behaviour of the supply you will use.

Spray-up requires suitable equipment. Condition the mould, resin and workshop before starting and plan application around PALV's gel time.

Spray-up requires suitable equipment. Plan application around the working time at the actual workshop temperature; MPALV has a longer gel time than PALV under the compared conditions.

For the reference system with GCS1001E PA gelcoat, validate the complete laminate: reinforcement, thickness, finish and cure. The fire classification does not transfer to any part. This gelcoat is spray-applied and intended to be painted afterwards.

Crestafire GCS1001E PA: Spray gelcoat for the reference fire and smoke system with P1-3001PA. The complete part and its finish must be validated.

Applied before laminating. An excessively thick film can lose transparency; control thickness and allow for the heat cure needed to demould and complete the part.
