Definitions
- the present invention relates to a mixture of non-reactive thermoplastic polymer and reactive thermoplastic polymer and its use with a fibrous material for the preparation of a fibrous material impregnated with said mixture thus constituting a composite.
- thermoplastic polymers to make composites comes up against the difficulty of impregnating the fibrous material because of the high viscosity in the molten state of thermoplastic polymers, in particular when they have a high Tg. too much the molar mass of these polymers they then become brittle and the composites made from these resins are less efficient.
- thermoplastic polymers of high Tg that is to say Tg> 80 ° C, preferably> 100 ° C
- Tg> 80 ° C, preferably> 100 ° C thermoplastic polymers of high Tg
- International application 2014/013028 describes a process for impregnating a fibrous material with a mixture of (meth) acrylic monomer and (meth) acrylic polymer.
- International application WO 2016/207553 describes the use of prepolymers that are reactive with one another or of a prepolymer comprising two different reactive functions which are reactive with one another for the preparation of composites by pultrusion.
- the critical molar mass to be achieved for the final polymer to be ductile will be all the more important as this polymer is very rigid, which is particularly true for high Tg aromatic polymers
- the starting molar mass must be low to allow great fluidity for processing, in particular for making composites
- the only possibility of obtaining a ductile polymer and / or a composite having good mechanical properties will be to extend the manufacturing cycle time of composite parts to allow a sufficient molar mass to be achieved during in situ polymerization, which is counterproductive from an in-situ point of view industrial.
- this polymer In the case of the manufacture of a film or a veil based on polymer fibers, this polymer must have a sufficient viscosity in the molten state to be compatible with the manufacturing process of the film or of the polymer. veil. If we want to be able to easily and quickly impregnate reinforcements or dry fibrous materials from the hot pressing of this film or this veil on the dry fibrous reinforcement (so-called film stacking process or “film stacking”) it is necessary to It is advantageous to use a reactive composition to make this film or this web so as to limit its viscosity in the molten state to a value sufficient for its use and not too high to allow good impregnation of the fibers. But making a film or veil only composed of a prepolymer risks leading to a very fragile product that is unsuitable for the handling required at room temperature to assemble with the dry fibers, before hot pressing.
- the present invention therefore relates to the use of a composition
- a composition comprising a mixture of at least one non-reactive thermoplastic polymer with Tg> 40 ° C, in particular> 100 ° C, in particular> 120 ° C, and at least one reactive thermoplastic prepolymer, with a fibrous material, for the preparation of a fibrous material impregnated with said composition, said composition exhibiting an initial viscosity in the molten state during impregnation, as measured in plane-to-plane rheology at 1 Hz and 2% deformation, at a temperature of 300 ° C, less than the viscosity of the same composition devoid of reactive prepolymer, measured under the same conditions and / or ductility, after in situ polymerization of said reactive thermoplastic prepolymer in said composition during impregnation and after said impregnation, at least equivalent, in particular greater, to the ductility of the same composition devoid of non-reactive thermoplastic polymer, and in which said reactive thermoplastic
- composition comprising a mixture of at least one non-reactive polymer with at least one reactive polymer allows the preparation of a fibrous material impregnated with said composition with good and rapid impregnation and in particular with a non-reactive high Tg polymer in the mixture, thus leading to high-performance composites, that is to say having good mechanical properties.
- either the composition exhibits an initial viscosity in the molten state during impregnation and after impregnation, as measured in plane-to-plane rheology at 1 Hz and 2% deformation, at a temperature of 300 ° C, which is lower than the viscosity of the same composition devoid of reactive prepolymer and measured under the same conditions, i.e. the ductility of said composition in which the reactive prepolymer was polymerized in situ during the impregnation and after the impregnation is greater than or equal to the ductility of the same composition devoid of non-reactive thermoplastic polymer and in which said reactive thermoplastic prepolymer is polymerized at the same average molecular mass, i.e. the viscosity and the ductility both evolve as described above, for that the impregnation is good and rapid and thus leads to high-performance composites, that is to say having good mechanical properties.
- initial viscosity in the molten state means that the molar mass in number Mn of the prepolymer in the composition during the initiation of the impregnation has not changed by more than a factor of 1.5 to 2. relative to the initial molar mass before impregnation.
- the Tg is determined by DMA according to ISO 6721-11: 2019.
- the molar mass in number (Mn) and in weight (Mw) of the polymers was determined by size exclusion chromatography according to ISO standards 16014-1: 2012, 16014-2: 2012 and 16014-3: 2012 using the conditions following:
- the viscosity in the molten state is measured by oscillatory rheology at a temperature of 300 ° C, on a Physica MCR301 apparatus between two parallel planes 25 mm in diameter.
- the viscosity measurement is carried out over a maximum time of ten minutes.
- non-reactive thermoplastic polymer means that the thermoplastic polymer has a molecular weight which is no longer liable to change significantly, that is to say that its number-average molecular weight (Mn) changes by less than 20% before its implementation.
- thermoplastic polymer is capable of reacting in the composition during its use.
- reactive thermoplastic prepolymer means that the molecular weight Mn of said reactive prepolymer will change during the subsequent processing of the composition by reaction of reactive prepolymers with one another or of a reactive prepolymer on itself, by condensation with release. of water or by substitution or by reaction of reactive prepolymers with a chain extender by polyaddition and without elimination of volatile by-products to lead subsequently after use to a final non-reactive thermoplastic polymer.
- the latter After mixing the reactive prepolymer and the non-reactive polymer for the constitution of the composition and impregnation of the fibrous material with said composition, the latter remains thermoplastic.
- ductile refers to the ability of a material to deform plastically without breaking.
- the TDF as determined according to the ISO 179 1eA standard, is at the Ductile-Brittle transition temperature which corresponds to the temperature at which a material changes from ductile behavior (partial breakage of the material) to brittle behavior (rupture complete material).
- the ductile-brittle transition can therefore be seen as a temperature range where there is 50% brittle failure (brittle behavior of the sample) and 50% partial failure (ductile behavior of the sample) and a competition between behavior ductile and brittle behavior.
- the ductile-brittle transition therefore corresponds to the inflection point of the resilience curve as a function of temperature.
- the TDF of the composition after in situ polymerization of said reactive thermoplastic prepolymer in said composition during impregnation and after impregnation is greater than or equal to the TDF of the same composition devoid of non-reactive thermoplastic polymer, including said prepolymer.
- reactive thermoplastic is polymerized to the same average molecular weight as after impregnation.
- said ductility after in situ polymerization corresponds to an elongation at break at 23 ° C. greater than 10% as measured according to ISO 527-1 / 2.
