    Composite Materials Testing

    Composite material is a kind of material which is composed of two or more different materials in different ways. It can give full play to the advantages of various materials, overcome the defects of a single material and expand the scope of application of materials. Because composite materials have the characteristics of light weight, high strength, excellent elasticity, chemical corrosion resistance and good weather resistance, they have gradually replaced wood and metal alloys, and are widely used in aerospace, automotive, electronic and electrical, construction, chemical, textile and machinery manufacturing field. As a professional reliability third-party testing organization, T,C&A Lab can provide Composite Materials Testing service according to ISO, ASTM standards and industry requirements. Welcome to contact our experts for consultation.

    Characterization of mechanical properties of composites

    Mechanical properties include tension, compression, bending, shear, impact, hardness, fatigue, etc. These data must be obtained in strict accordance with the standard.

    • Tensile Testing

    Non-destructive testing of composite materials

    Because the anisotropy of composite materials and process conditions are difficult to be completely consistent, resulting in greater dispersion of product quality, sampling samples often cannot represent the overall level of the batch of products. In order to make the damage data of all products above the design requirements, it is often too conservative to take the safety factor, which will increase the cost, especially in some specific occasions. Therefore, non-destructive testing methods that test the quality level of the product without damaging the product are particularly important for composite materials. Defect forms and detection methods of composite materials include:

    • Local defects: bubbles, delamination, inclusions, cracks, etc.
    • Ultrasonic flaw detection can be carried out by vertical longitudinal wave or pulse echo and penetration method.

    • Integral defects: looseness, microcracks, too much or too little resin, etc.
    • They can be judged by ultrasonic speed measurement or signal attenuation change. Because of its small change value, a high-resolution probe is required.
