Hand lay-up

Hand lay-up is the simplest moulding technique used to produce composite parts; popular in the industry not only for its ease of execution, but also for the low cost of the equipment required to implement it. This system consists of applying layers of resin and fabric, alternated with the removal of air bubbles, until the desired thickness is reached. In order to obtain a correct resin-fibre ratio, and therefore better mechanical resistance of the part, it is recommended to apply a peelply as the last layer to be removed when the resin has hardened. The process requires the surfaces to be perfectly clean, as otherwise they could compromise the final appearance and structural behaviour of the product.
