Bulk moulding compounds represent a family of chopped fibre thermoset or thermoplastic-based composite materials. Fibre lengths are typically 1/2 inch, 1 inch or 2 inches (6 to 50 mm). Longer fibres provide higher tensile strengths while shorter fibres allow more complex shapes to be moulded. Standard modulus and intermediate modulus carbon fibres are utilized.
Benefits of bulk moulding compounds include:
TenCate offers a complete line of epoxy-based thermosets, and also offers a line of thermoplastic-based chopped carbon fibre moulding compounds using PEEK and PPS. Other thermoplastic resin systems may be available upon request. Thermoplastic-based resins offer low moisture uptake, good impact resistance and low flame, smoke and toxicity. Thermoset resins are precision coated and designed to be low flow for optimal high fibre/resin content.
- Strength and stiffness of metallic parts like aluminum with 40% less weight.
- Allows the fabrication of complex shapes with varying cross sections in one efficient compression molding cycle.
- Allows for the fabrication of precise and integrated composite structures.
- TenCate now offers both thermoset and thermoplastic resin based chopped fiber bulk molding compounds.
