Abstract
The invention relates to a thermoplastic composite comprising: at least one straight portion having a circular section with an external diameter, and a longitudinal axis, at least one bent portion, at least one bending radius, of the at least one bent portion the bending radius being at most a factor f equal to 5 with respect to the external diameter of the at least one straight portion, and a thermoplastic matrix and a fiber reinforcement. The invention also relates to a structure to be reinforced comprising at least one thermoplastic, uses of a thermoplastic composite and a method for producing a thermoplastic composite.
Claims21
A thermoplastic composite comprising:
- at least one straight portion having a circular section with an external diameter and a longitudinal axis,
- at least one bent portion,
- at least one bending radius, of the at least one bent portion the bending radius being at most a factor f equal to 5 with respect to the external diameter of the at least one straight portion, and
- a thermoplastic matrix and a fiber reinforcement.
(canceled)
Method for producing a thermoplastic composite comprising at least one straight portion having a circular section with an external diameter and a longitudinal axis, and at least one bent portion, the method comprising:
- A step of providing the thermoplastic composite with at least one straight portion having a circular section with an external diameter, said thermoplastic composite comprising a thermoplastic matrix and a fiber reinforcement,
- A step of heating a portion of the thermoplastic composite, preferably from, conduction, convection, radial and/or volumetric heating,
- A step of creating at least one bent portion in the heated portion by bending the heated portion according to a bending radius, the bending radius being at most a factor f equal to 5 with respect to the external diameter of the at least one straight portion of the thermoplastic composite,
- A step of cooling the at least one bent portion to form a thermoplastic composite comprising at least one straight portion and at least one bent portion.
