3R, Official Testing Partner of the Pont Bridge Challenge at SAMPE France Technical Days 2025

We are pleased to announce our participation as sponsor and testing partner at the SAMPE France Technical Days 2025. This year, the event will take place on November 20 and 21, 2025, at Compositadour in Biarritz. For this first collaboration with SAMPE, 3R will be in charge of conducting the mechanical testing for the Pont Bridge Challenge, one of the highlights of this technical event focused on composite materials.

The Pont Bridge Challenge at the Heart of SAMPE 2025 Technical Days

This challenge is reserved for composite industry professionals and engineering students. It pits teams from various engineering schools against each other in a competition to design and build a composite bridge capable of withstanding increasing loads.

The tests will be performed live on our Syntax 100S universal testing machine, which will be installed on site. This setup will allow for precise, real-time measurement of each structure’s mechanical performance up to failure.

A Partnership Rooted in French Manufacturing

This partnership reflects a shared commitment to promoting French industrial expertise. 3R is a France-based designer and manufacturer of mechanical testing systems. Since 2012, we have held the Origine France Garantie certification, confirming our commitment to domestic production.

By selecting 3R as the technical partner for the Pont Bridge Challenge, SAMPE France highlights national engineering excellence and reaffirms its support for French innovation in the composites sector.

For 3R, joining the SAMPE France Technical Days as a sponsor reinforces our long-standing involvement in composites testing, research, and education.

Live Testing: The Syntax 100S at the Core of the Challenge

To evaluate the bridges designed by student teams, 3R will provide its Syntax 100S universal testing machine. Developed and manufactured in France, this equipment is known for its robustness, precision, and adaptability to high-load composite testing.

Designed for large-capacity mechanical testing, the Syntax 100S features a rigid structure and advanced control system. It ensures accurate measurement of applied forces up to failure, along with reliable strain and load data acquisition.

Key Features of the Syntax 100S:

Load capacity up to 100 kN
Dual ball screws with preloaded backlash-free nuts, ensuring stable transmission
Hybrid drive system combining reinforced belt and high-efficiency planetary gearbox
Closed-loop control for optimal precision
Compatible with high-resolution sensors and extensometers
User-friendly, configurable interface, suitable for both academic and industrial use
Fully compliant with ISO 7500 standards
