BIO4SELF

BIO4SELF aims at fully biobased self-reinforced polymer composites (SRPC). To produce the SRPCs two polylactic acid (PLA) grades are required: a low melting temperature (Tm) one to form the matrix and an ultra high stiffness and high Tm one to form the reinforcing fibers. To reach unprecedented stiffness in the reinforcing PLA fibers, we will combine PLA with bio-LCP (liquid crystalline polymer) for nanofibril formation. Further, we will increase the temperature resistance of PLA and improve its durability. This way, BIO4SELF will exploit recent progress in PLA fiber technology. We will add inherent self-functionalization via photocatalytic fibers (self-cleaning properties), tailored microcapsules (self-healing properties) and deformation detecting fibers (self-sensing).

Prototype composite parts for automotive and home appliances will be demonstrators to illustrate the much broader range of industrial applications, e.g. furniture, construction and sports goods. Our developments will enable to use biobased composites for high end applications, thus contributing to using sustainable and renewable raw materials. Being able to produce, process and sell these novel SRPCs and related composite intermediates will be a clear competitive advantage. First estimates predict a market of at least 35 kton/year, corresponding to ca. 165 M€, within 5 years.

BIO4SELF is a well balanced mix of end users (large enterprises to maximize impact), technology providers (mainly R&D driven SMEs), R&D actors (RTDs and universities) and innovation support (specialized SMEs). It covers the required expertise, infrastructure, and industrial know-how to realize the innovation potential of the novel high performance biobased SRPCs, both during and beyond the project.
