A

Statement of Task

This 2-day public workshop will discuss future advances in weight reduction by materials substitution for vehicles, including, but not limited to topics such as Armor, Structure, Automotive Parts, and Armaments. Vehicle weight reduction is an effective strategy for improving fuel consumption in civilian vehicles. For combat vehicles, it presents not only an important opportunity to reduce fuel use and associated logistics, but also important advantages in transport and mobility on the battlefield. This workshop will focus on materials substitution as a means towards weight reduction. It will examine possibilities for weight reduction in the vehicle structure, power train and running gear, and armor and armaments, while meeting system level performance and life cycle sustainment requirements it will also investigate the feasibility of weight reduction goals in the 50-60 percent range by the 2030-2040 timeframe principally by engineering methods using materials substitution.

The workshop is divided into three main topics:

  • Armor issues,
  • Structure and automotive issues, and
  • System effects and testing.

Potential sub-topics include the development of new metal alloys, ceramics, glass materials and composites, with attention to engineering approaches to take advantage of the new materials. It is not the intent of this workshop to address the full systems engineering trade space for a lightweight force, but rather to focus on contributions to light-weighting engineering enabled by advances in materials substitution.

Vehicle weight reduction is an effective strategy for reducing fuel consumption in civilian vehicles. For combat vehicles, it presents not only an important opportunity to reduce fuel use and associated logistics, but also important advantages in transport and mobility on the battlefield. Although there have been numerous efforts in the past to reduce the overall weight of combat vehicles, combat vehicle weight has continued to increase over time due to new threats and missions.

On December 8 and 9, 2014, the National Academies of Sciences, Engineering, and Medicine held a workshop to explore opportunities in lightweight materials for armored vehicles. This was the ninth workshop in an ongoing series for the U.S. military on materials and manufacturing issues. The workshop discussed future advances in weight reduction by materials substitution for vehicles, including such topics as armor, structure, automotive parts, and armaments. This publication summarizes the presentations and discussions from the workshop.
