Use this tool to convert measurement units for linear density, tenacity, breaking strength, twist, and weight. Weight Weight

The composite pellet is manufactured through pultruding continuous fiber filaments that are melt permeated with polymer in an impregnation die, creating a product with 20% to 60%, by weight, fiber content that is 12mm in length.     They are frequently used to replace metal for applications in which light weighting, improved impact strength, elastic modulus, and material strength are required.   Provides structural performance that can go head-to-head with metals at a fraction of the weight.

Dyneema® Unveils Breakthrough Innovation to Enable Weight Savings of up to 20% in Protective Body Armor Dyneema® Unveils Breakthrough Innovation, Dyneema® SB301 to Enable Weight Savings of up to 20% in Protective Body Armor.     Hammerhead™ Marine Composite Panels from Avient remove weight and streamline production in marine manufacturing. 

However, improving panel performance can come at the cost of increasing weight. Performance and weight must be thoughtfully balanced, as a primary advantage of thermoplastic composite panels is greater strength-to-weight ratio than traditional panel materials.
