While compounding with filled systems
- , some of the crucial elements to be taken into account include:
- Volume fraction of filler
- Particle characteristics (size, share, surface area…)
- Filler aspect ratio
- Strength and modulus of filler
- Adhesion of filler to the resin
- Viscosity of the base resin
- Toughness of the base rein
Nanoparticle-reinforced epoxy composites have also generated considerable industrial interest over past decades. These materials have high specific strength-to-weight ratio, low density, and enhanced high modulus, which permits them to contend with selected metals.
The primary aim of reinforcing-blending of epoxies is to achieve the desired properties while keeping low costs. Increasing filler content generally increases viscosity and makes processing more difficult. Specific gravity usually increases, although some fillers like hollow glass or phenolic micro balloons make syntactic foams of significantly reduced density.
Rubber Additives – They are used to increase flexibility, fatigue resistance, crack resistance, toughness in epoxy resins. The liquid rubbers most often used in epoxy composites are carboxyl-terminated butadiene acrylonitrile copolymer (CTBNs). However, the acrylonitrile content of the rubber is an crucial regardation when using a rubber modifier. As the nitrile content of a rubber increases, its solubility increases and eventually particle size in the cured matrix decreases. Unreactive rubbers are not used in epoxy composites uses.
