Liquid crystalline polymers (LCP) and/or thermoset precursors of epoxy based resins with liquid crystalline properties will be blended with pure and recycled PET, in order to increase its mechanical properties, toughness, coefficient of thermal expansion, dimensional stability and barrier properties.
In order to overcome interfacial transverse bonding weakness in liquid crystalline polymers and their blends, innovative reaction alloying and solid state chemistry are utilised to produce new materials based on large scale usage polymers such as PET and epoxy resins blended with commercial, modified or specifically targeted liquid crystalline polymers.
The objective to develop new materials is focused on the high potentiality of liquid crystalline bases polymers in applications where the additional material and processing costs are justified by a significant increase of the benefits, in particular :
- fibrous composites with liquid crystalline thermosetting matrices characterized by an additional reinforcing effect in the direction perpendicular to the fibres.
- LCP/PET blends for fibres and in situ composites with improved LCP/host polymer adhesion.
- high gas barrier materials for bottles and films.
- multilayer barrier films.
- self reinforcing liquid crystalline thermosets.
