Resumen:
Una pyme francesa está desarrollando materiales poliméricos termoplásticos reforzados con fibras cortas naturales. Las fibras son tratadas previamente con calor. Gracias a este proceso patentado, las fibras no emiten ningún olor y tienen un mayor módulo elástico, lo que permite diseñar componentes más delgados y ligeros. Este material innovador puede emplearse en numerosos ámbitos, especialmente en la industria de automoción. La empresa busca socios con el fin de establecer acuerdos de financiación o fabricación.

Tittle:
French SME has developped an innovation in natural fibres / thermoplastic composites
Summary:
The French SME is developing composites of thermoplastic polymers reinforced with short natural fibres. The fibres are heat-treated prior to compounding. With this patented process the parts doesn´t emanate any smell and have an increased elastic modulus, thus allowing to design thinner parts which are lighter. The innovative material could be used in many fields and especially in auto industry. The French SME is looking for partners to settle a financial agreement or a manufacturing agreement.
Description:
The French SME is developing composites of thermoplastic polymers reinforced with short natural fibres. The fibres are heat-treated prior to compounding. This patented process leads to an innovative material whose elastic modulus is increased. This allow both to design thinner parts which are lighter and to save of raw materials. The heat treatment also suppresses the smell emitted by the fibres during and after the injection of the composites parts. The process is applicable to most of the natural fibres and to thermoplastic polymers whose extrusion temperature is below 250 degrees celsisus.
The new process is the result of a research and developpement project carried out between 2012 to 2015 by the French SME together with 4 research laboratories and the local university, one technological research center and 3 plastic parts manufacturers.
The French SME is looking for partners to establish a financial agreement willing to invest in the industrialisation of the product or a manufacturing agreement if the partner is willing to have their parts manufactured with this innovative material.
Advantages and Innovations:
The organic-plastic composite has the following characteristics:
- Greater elastic modulus, thus allowing to design thinner parts which are lighter and to save of raw materials.
- Lighter weight and better stiffness: in a polypropylene matrix, treated hemp fibres (30% of weight) lead to an increase of 15% of elastic modulus versus non treated fibres (with the same weight ratio), which allows to design parts whose weight is 15% lighter, and for which raw materials savings can be around 15%.
- Composites properties (independent of retting degree) : the composites using non treated fibres have colour and mechanical properties depending on the degree of retting of hemp (or of flax). Manufacturers often prefer highly retted fibres . The French SME treatment of the fibres suppresses this dependency, thus ensuring stability of composites properties.
- No smell: composites made of treated fibres don´t emanate any odours during and after moulding.
- Easiness of injection moulding: A variety of parts were moulded on industrial injection presses, using polypropylene reinforced with treated and with non-treated fibres. It has been observed that the composite material using the treated fibres has a better thermal stability and lead to a better flow in the mould.
- Reduced fouling of the mould: During injection moulding, non-treated fibres usually exude compounds which migrate to the mould surface. This phenomenon requires periodic cleaning of the mould and this is significantly reduced when treated fibres are used.
