Charpy Impact Strength Testing Services

Why Charpy Impact Testing Is Important

The Charpy Impact Strength Test helps identify a material’s ductile-to-brittle transition temperature and impact absorption capacity. These parameters are vital in determining how materials behave under different service conditions — especially in automotive, aerospace, packaging, and civil engineering applications.

• Ensures product safety and reliability under impact.
• Evaluates resistance to crack propagation.
• Helps in selecting suitable materials for critical applications.
• Validates quality for production and academic research projects.

At Kiyo R&D Lab, every impact test is carried out using calibrated instruments and trained professionals who follow ASTM and ISO standards.

Types of Materials Tested at Kiyo R&D Lab

• Metals and Alloys (mild steel, aluminum, copper, etc.)
• Engineering Plastics (ABS, Nylon, Polycarbonate)
• Composite Panels (FRP, carbon fiber, glass-reinforced composites)
• Rubber-based components and packaging materials

Our facility is equipped to test a wide range of specimens according to both Charpy and Izod impact methods, depending on client requirements.

How the Charpy Impact Strength Test Works

1. Specimen Preparation: Samples are machined to a standard size with a precise notch to control fracture initiation.
2. Mounting: The specimen is placed horizontally between two supports on the impact testing machine.
3. Impact: A pendulum of known energy strikes the specimen at a controlled speed.
4. Measurement: The energy absorbed by the specimen before fracture is automatically displayed on the machine’s digital indicator.
5. Reporting: The absorbed energy (in Joules) is reported as the material’s impact strength.

Key Parameters Evaluated

• Impact Energy (J)
• Fracture Appearance (ductile / brittle)
• Temperature-dependent behavior
• Notch Sensitivity

Industries Benefiting from Charpy Testing

• Automotive: Vehicle body panels, bumpers, and chassis components.
• Aerospace: Structural and composite parts requiring impact resistance.
• Construction: Steel and polymer components used in safety-critical structures.
• Packaging: Plastics and films requiring drop or shock resistance.
• Academic & Research: Engineering colleges validating student projects and prototypes.
