Sommaire
Epoxy resins in high-performance composites
Epoxy resins are widely used in the manufacture of composites with high mechanical performance. They are found in particular in the following sectors:
- aeronautics
- aerospace
- automotive
- mechanical engineering industry
Epoxy composites are particularly valued for their stiffness, mechanical strength, and excellent fatigue resistance. According to composite material manufacturers such as Hexcel, these materials make it possible to produce very lightweight structures while maintaining high mechanical strength.
Emissions generated during processing
Processing epoxy resins involves several steps that can generate chemical emissions.
Key operations include:
- mixing resins and hardeners
- fibre impregnation
- thermal curing
During these steps, chemical fumes and volatile organic compounds may be released into the air. These emissions can spread throughout the workshop if they are not captured.
Risks associated with resin fumes
Exposure to epoxy resin fumes can cause various health effects. According to occupational risk prevention bodies, certain substances used in resins may lead to:
- respiratory irritation
- skin irritation
- allergic sensitisation
In composite workshops, these emissions can also contribute to a deterioration in air quality.
OberA solutions for capturing fumes
Implementation of:
- 1 x ePURBOX ATEX with arm to capture organic pollutants at source
- 1 x ePURBOX ATEX table version for the formulation workstation
- 1 x CLEARBOX G4 + carbon version connected to a 1200 x 1000 floor-mounted back panel to capture a mixing workstation
