SMC per l’aeronautica


The aviation industry is one of the branches with the highest growth during the last years. Lightweight design and the use of lightweight materials such as carbon fiber reinforced plastics are important key aspects for meeting the rising need for fuel-efficient civil aircraft in the future.

For the cost-efficient and lead-time-related production of aircraft structures or components the development of innovative manufacturing technologies is necessary.

In this context the combination of pre-impregnated continuous fiber reinforcements and sheet molding compounds reinforced by long fibers in a one-shot compression process is really promising.

By using this hybrid material and this process technology functional and lightweight composite components can be realized in a cost-saving way and with short lead times. The direct implementation of metal components such as inserts, sleeves and plates promises further functional integration.

Polynt Composites has invested many efforts in research and development for new class of thermoset reinforced materials to react to the increasing aircraft market requests. In particular it has been launched a new range of SMC for aircraft industries in its German plant in Miehlen (near Frankfurt) such as:

  • HUP 27: The SMC described by HUP 27 is developed for the fire containment requirements for cargo areas and fulfills the FAR requirements according FAR 25 App. F, Part I + V and the AITM 3.005.
  • HUP 63: The SMC described by HUP 63 is developed for the fire containment requirements for cabin and interiors and fulfills the FAR requirements according FAR 25 App. F, Part I + V and the AITM 3.005.

Both SMC can be co-molded with carbon fiber reinforcement (fabrics or unidirectional) impregnated with the same thermosetting resins in order to give the same continuity on the organic phase.

Progettare nello stesso momento materiali e strutture, per massimizzare le caratteristiche meccaniche del prodotto: è così che si può davvero trarre vantaggio dai materiali ingegnerizzati. Un software di simulazione è un alleato prezioso per il progettista di laminati in composito: consente di prevedere le prestazioni dei materiali, individuare le soluzioni progettuali più efficaci e analizzare tutte le interazioni tra fenomeni fisici, prima ancora della prototipazione. …
