Timepiece component made of forged composite
View Patent ↗The present invention relates to a timepiece component ( 100 ) made up of a polymer-based matrix ( 110 ) and a reinforcement ( 120 ) that consists of at least two different kinds of cut fibres ( 121, 122 ), one of which is a polyazole.
1. A timepiece component made up of a polymer-based matrix and a reinforcement, wherein the reinforcement consists of fibres of at least two different kinds in cut form, one of which is a polyazole, wherein the matrix is designed for identification and authentication of the timepiece component by comprising nano- or micro-fillers in a proportion of between 0% and 4% by weight of the matrix, and by disposing the fibers in a random manner, and wherein said nano- or micro-fillers are chosen from graphene, pigments, mineral fillers or particles of precious metals.
2. The timepiece component according to claim 1 , wherein the second kind(s) of fibres is/are chosen from carbon fibres, basalt fibres, glass fibres, natural fibres and ceramic fibres.
3. The timepiece component according to claim 1 , wherein the fibres have a length of between 2 mm and 70 mm.
4. The timepiece component according to claim 1 , wherein the fibres have a length of between 4 mm and 50 mm.
5. The timepiece component according to claim 1 , wherein the reinforcement comprises between 20% and 80% by weight polyazole fibres.
6. The timepiece component according to claim 1 , wherein the reinforcement comprises between 0% and 80% by weight carbon fibres.
7. The timepiece component according to claim 1 , wherein the reinforcement comprises between 0% and 80% by weight basalt fibres.
8. The timepiece component according to claim 1 , wherein the matrix is a polymer.
9. The timepiece component according to claim 1 , wherein the mass proportion of the matrix with respect to the reinforcements is between 25% and 50%.
10. The timepiece component according to claim 1 , wherein the matrix comprises pigments having an identical colour in the visible spectrum and under UV radiation.
11. The timepiece component according to claim 1 , wherein the pigments have a different colour in the visible spectrum and under UV radiation.
12. The timepiece component according to claim 1 , wherein the pigments have a different colour in the visible spectrum and under infrared radiation.
13. The timepiece component according to claim 1 , wherein said nano- or micro-fillers are chosen from graphene or particles of precious metals.
