Quick Answer
Rawhide cordage can hold up against moderate loads, but its capacity for heavy loads is limited due to its relatively low tensile strength and susceptibility to decay.
Material Properties
Rawhide cordage is a type of cordage made from animal hide, typically cowhide or buffalo hide. It has a tensile strength of around 200-400 pounds per square inch (PSI), which is lower than other types of cordage such as nylon or Kevlar. The strength of rawhide cordage depends on the thickness of the hide, the method of tanning, and the quality of the raw materials.
Load Capacity
While rawhide cordage can hold up against moderate loads, it is not suitable for heavy loads. A general rule of thumb is to limit the load to around 10-20% of the cordage’s tensile strength. For example, a rawhide cordage with a tensile strength of 300 PSI should not be used to support loads exceeding 30-60 pounds (10-20% of 300 PSI).
Techniques for Strengthening Rawhide Cordage
To improve the load capacity of rawhide cordage, it can be treated with various techniques such as waxing, oiling, or braiding. Waxing or oiling can help to reduce moisture absorption and prevent decay, while braiding can increase the tensile strength of the cordage. It is also essential to use high-quality rawhide and to follow proper handling and storage procedures to maximize the lifespan of the cordage.
