Chopped Strand Mat

Chopped Strand Mat

Chopped strand mat is a widely used reinforcing material in the composites industry. Its production process involves cutting glass fibers into short lengths of about 50mm, randomly distributing them to form a mat, and then bonding them together with an appropriate adhesive. Its main characteristics are as follows:

  • Strength: CSM has high tensile strength, making it suitable for large area parts and structural applications.
  • Compatibility: It is compatible with various resins, including polyester, vinyl ester, epoxy, and phenolic resins.
  • Flexibility: The random orientation of fibers allows the mat to easily conform to complex shapes, facilitating hand lay-up and molding processes.
  • Chemical and Moisture Resistance: The glass fibers used in CSM offer excellent chemical corrosion resistance and moisture resistance, enhancing the durability of composite structures.
  • Electrical Performance: Glass fibers have good electrical insulation properties, making CSM suitable for applications requiring electrical insulation.

Continuous Filament Mat

Continuous filament mat is a versatile, high-performance reinforcement material used in various industries such as marine, construction, transportation, and energy. Its production process involves drawing continuous glass fibers, randomly orienting them, and bonding them with an appropriate adhesive. Its characteristics are as follows:

  • High Tensile Strength: CFM can withstand tensile forces in both dry and wet conditions, increasing strength in all directions.
  • Excellent Wet-Out: This mat enhances the wet-out capability of individual glass filaments and strands, promoting complete resin impregnation.
  • Porosity: It offers minimal resistance to resin flow, facilitating complete resin impregnation, and is beneficial for processes such as vacuum infusion and resin transfer molding (RTM).
  • Adaptability: The mat can conform to complex shapes without wrinkling or leaving resin-rich areas that might lead to laminate cracking.
  • Compatibility: CFM is compatible with various resin systems, including polyester, vinyl ester, polyurethane, and epoxy resins.

Fiberglass Surface Tissue

Fiberglass Surface Tissue

Fiberglass surface tissue, also known as fiberglass veil or surface veil, is a thin, lightweight non-woven fabric made from randomly oriented glass fibers. It is primarily used as a surface layer in composite laminates to improve surface quality and provide additional benefits.

  1. Thin and Light:
    • Fiberglass surface tissue is very thin, typically weighing about 25-30 grams per square meter, resembling tissue paper.
  2. Smooth Surface:
    • It covers the coarse glass patterns produced by chopped strand mat (CSM) and other reinforcements, creating a smooth, resin-rich surface that is aesthetically pleasing and prevents print-through of underlying fibers.
  3. Enhanced Resin Flow and Wet-Out:
    • This veil wets out quickly and is easily impregnated by resin, helping achieve consistent, high-quality laminates. Depending on the substrate and application method, it typically requires about 70-100 grams of resin per square meter.
  4. Enhanced Durability:
    • By forming a resin-rich surface, the veil improves the laminate’s resistance to corrosion, UV radiation, and moisture, thus enhancing the durability and lifespan of composite structures.
  5. Compatibility:
    • It is compatible with various resin systems, including polyester, vinyl ester, epoxy, and phenolic resins, making it suitable for diverse composite applications.

Battery Separator Tissue

Battery separator tissue is a critical component in the construction of various types of batteries, including lithium-ion and lead-acid batteries. It serves multiple functions such as preventing short circuits, enhancing ion conductivity, and improving the overall safety and performance of the battery.

  1. Mechanical Strength:
    • Glass fiber and polyolefin separators have high mechanical strength, crucial for maintaining battery structure integrity during operation.
  2. Thermal Stability:
    • Cellulose-based separators exhibit better thermal stability than polyolefin separators, making them suitable for high-temperature applications.
  3. Electrolyte Absorption and Wettability:
    • Cellulose-based separators have high porosity and excellent electrolyte absorption capability, improving ion conductivity and overall battery performance.
    • Glass fiber separators also have good wettability, ensuring effective electrolyte distribution within the battery.
  4. Safety Features:
    • Advanced separators, such as those incorporating nano-silica or other hybrid materials, enhance flame retardancy and thermal stability, thereby improving the safety of lithium-ion batteries.
