Descrizione del progetto
Verso una nuova generazione di compositi sandwich leggeri
La crescente domanda di risparmi energetici e riduzione delle emissioni nel settore dei trasporti ha portato a un interesse per i compositi sandwich leggeri. Tuttavia, questi erano fortemente limitati dalle proprietà dei materiali compositi leggeri. Pertanto, è stato concepito un processo in due fasi per creare un composito di poliestere insaturo schiumato rinforzato con fibra (FR-FUP) come nucleo leggero di compositi sandwich. Il progetto TESCOM, finanziato dall’UE, mira a risolvere alcuni problemi scientifici centrali dei compositi FR-FUP e a fornire una base teorica per lo sviluppo di compositi sandwich leggeri di nuova generazione. Per fare ciò, si concentrerà sulla creazione di compositi FR-FUP con elevate proprietà meccaniche, elevate prestazioni ignifughe e buona progettabilità. Questo lavoro rivestirà un ruolo significativo nella promozione di tecnologie ecocompatibili per il settore dei trasporti.
Obiettivo
With the increasing demand for energy saving and emission reduction in the transportation industry, the study on lightweight sandwich composites (LSCs) has attracted much attention during the past two decades. However, current LSCs were strongly limited by the properties of lightweight core materials. In this context, a two-step process was designed to prepare fibre reinforced foaming unsaturated polyester composite (FR-FUP) as a novel lightweight core of sandwich composites. The pre-foaming sheet is prepared as the basic component of FUP composites, which make it possible to form the foam core material in situ when preparing the sandwich composites. In this project, aiming at solving some key scientific problems of FR-FUP composite and providing theorical base to the development of new generation LSCs. Based on the targeted molecular design and synthesis of UP polymer matrix, and the modified pre-foaming sheets, the fellow will focus on the advanced FR-FUP composites with high mechanical properties, high flame retardant performance and good designability. The main objectives include: (1) to find an optimal polymer matrix for the two-step molding process of FR-FUP composites by click polymerization; (2) to establish structure-property relationship between tailored UP resin and FR-FUP composites; (3) to prepare multifunctional lightweight composite and expand its application in transportation industry. This proposal presents an interdisciplinary and innovative approach with great significance. The original ideas will bring us bran-new to design and prepare LSCs.
