Heavy Truck

Under-the-hood parts in Heavy Truck industry are subject to high temperatures, corrosive substances, and physical constraints. However, the shelf-life parts is linked to the shelf-life vehicle, lasted several years or several decades.
Rising costs for aluminium, zinc and under pressure molded magnesium, with new emissions regulations and increasing performance requirements, lead design engineers and manufacturers to convert to BMC (Bulk Molding Compound) and SMC (Sheet Molding Compound) thermoset composites for many under-the-hood parts in Heavy Truck industry.

The unique physical properties of BMC and SMC materials make them the perfect alternative of metal replacement for these applications.
Thermoset composites materials have a high strenght/weight ratio, and an excellent NVH (Noise Vibration Harshness) ranking, which make them effective in the normal sound vibrations reduction.

Other characteristics that make BMC and SMC materials ideal for Heavy Truck applications include :
  • thermal resistance : preserving the dimensional control to engine heat exposure
  • corrosion resistance : resistance to corrosive substances commonly encountered in under-the-hood applications
  • light weight : lighter than steel parts of equal strenght up to 35%
  • consolidation parts : allow manufacturers to reduce the number of required components

Valve covers, distribution chain covers, oil bins and intake manifolds, are just few examples of under-the-hood parts benefiting of thermoset composites advantages in Heavy Truck industry, like the typical body parts applications.

Thermoset composites for Heavy Truck market offer a low coefficient of thermal expansion (comparable to steel), excellent dimensional stability, high impact strength, relatively low weight, paint receptiveness, and other major composite properties.
Thanks to all these excellent and high performance properties, the thermoset compounds are becoming the materiel of choice for manufacturers and designs engineers looking to develop new products.
