OLD PROTECTION

Sytem of protection with tyres and conveyor-belt We have analyzed several types of protections on different circuits.
Previously race tracks were protected with rows of tyres (with or without polyethylene tubes and with F1 conveyer belts) as well other type protection, plastic barriers. However, performance was limited and no system gave enough protection on the circuit to comply with current F.I.A regulations.

Additionally, installation was lengthy and both installation and maintenance were difficult.

NEW TYPE OF PROTECTION ON TRACK

After a five year research and development program in collaboration with DEKRA, the FIA Institute and the research laboratory (an innovator in rotational moulding).
TECPRO has developed a high security barrier for use on Formula 1 circuits.
The TECPRO barriers is made from the rotational moulding of flexible polyethylene as follows.
Dimensions (cm) : 150 L x 120 h x 60 w.
Weighs :120kg
3 nylon straps of 15 cm with resistance of up to 20T/cm2.
The barrier is filled with injected 'bendy' foam of flexible density.
A metallic sheet is placed at the centre which reinforces the barrier.

The main advantages of using TECPRO Barrier are:
- Maximum amount of energy absorption.
- Does not collapse upon impact.
- Cannot be over-ridden by F1 car (test 218 km/h).
- Reduction of impact 'G' force.
- Ease of installation
- Cost effective maintenance.

The concept

TECPRO Barriers are adaptable to all kinds of corner.
Barriers can be installed in a variety of ways.
The provision of the barriers is studied in accordance with the impact speed of a vehicle.

1) Average speed: One row of reinforced barriers (R1) is installed in front the metallic or concrete barrier and is separated by another two absorbent barriers (R2) also working as tensioners.
2) High speed: Two row of reinforced barriers (R1) is installed and is separated by two single absorbent barrier (R2) in front of another row of reinforced barriers (R1) which in turn are separated by another two absorbent barriers-tensioners (R2) ahead of the metallic or concrete barrier .

INSTALLATION OF TECPRO BARRIERS

Installation for impact has mean velocity < 90 km/h and < 140 km/h

< 90 km/h
LEGENDE :
(1) The row consists of absorbent reinforced anti perforated blocks.
(2) The red blocks have a role of absorbing energy and can also be used as a passage for security personnels and marshals.

< 140 km/h

Crash test

TECPRO have attended the FIA crash tests over the last five years at different speed levels such as 60 km/h, 140 km/h, 160 km/h 170 km/h, 187 km/h and 218 km/h.
Held under different climatic conditions, the Tests were declared successful by both Technicians, Engineers and FIA Representatives.

a) The TECPRO barriers had registered a high reduction of 'G' force when compared with other tested systems.
b) The TECPRO barriers did not collapse nor 'explode' in a crash.
c) The TECPRO barriers set up did not allow a vehicle to pass through the barrier.
d) It was possible to manually detach the crashed vehicle from the TECPRO barrier.

Types of block

The TEC PRO Barriers are adaptable to all kinds of turns.
Barriers are provided in accordance with the calculated speed of possible impact, in case of the exit of a vehicle.
