What are the resin-treated compressed wood laminates (compregs) - For electrical purposes?
Resin-treated compressed wood laminates (compregs) are composite of compressed wood laminations and are made of a combination of wood veneer or any other wooden material bonded together with a thermosetting resin. This process increases their mechanical characteristics and thus finds usefulness in electrical and structural applications. They possess a high strength-to-weight ratio, they have poor moisture absorption and it is a good electrical insulating material.
These laminates are applied where mechanical strength and electrical insulation properties are critical for their application such as electrical insulation boards, switch gear parts, electrical apparatus, etc. New Quality Control Orders (QCOs) promulgated by the Bureau of Indian Standards (BIS) serve the purpose of standardization of these products without compromising their safety and performance.
Manufacturing Process
The manufacturing of resin-treated compressed wood laminates involves several key steps:
- Material Selection:The candidates that can provide high mechanical and electric properties are chosen for application as wood veneer or fiber.
- Resin Application: An epoxy coating is applied on wood laminates and to the layers of wood that are being made. Some of the common types of styrene resins include phenolic styrene and epoxy styrene since they enhance bonding and excellent electrical insulation properties.
- Layering: The coated layers of resin are then piled up to make a laminate.
- Compression:The layered food piles that come into being are then covered up and put into a hydraulic press applying heat and pressure. This procedure helps to solidify the resin and simultaneously enshrine the layers’ firm attachment and increases their density.
- Finishing: Upon curing, the laminates are sanded and cut to exact dimensions to meet certain dimensional suitability.
This manufacturing process guarantees compregs with improved mechanical characteristics and dielectric strength for use in a wide range of applications.
Performance Requirement and Test Method
The performance requirements for resin-treated compressed wood laminates are outlined in Indian Standard IS 3513 (Part 3):1989. Key performance metrics include:
- Mechanical Strength: The laminate has to carry large loads without distorting or breaking down.
- Electrical Insulation Resistance: High insulation resistance is one of the most important requirements to minimize electrical leakage.
- Moisture Resistance: It should not be affected easily by humidity when it’s used in making the material.
- Thermal Stability: The properties of Compregs have to be retained at various temperatures.
Testing Methods
The detailed procedures for the testing of compregs are prescribed test methods to enhance accuracy in the results obtained. Common methods include:
ASTM D638:
Standard Test Method for Tensile Properties of Plastics, modified for compregs in order to measure tensile strength.
ASTM D149:
Test method for using Dielectric Strength of Solid Electrical Insulating Materials Under D.C. Voltage and Dielectric Breakdown Voltage.
IS 3513 (Part 3):
