Carbon Fiber Repair for Historic Buildings, Woodwork, Part 2

Methods for carrying the load of deteriorated joist ends using carbon fiber "mittens", information about the carrying capacity increase with each ply of carbon fiber tape on a timber, and a means of extending timbers with grafted elements like glass after casting an acrylic tooth cap to fit the damaged end of a timber, all designed with the wide-ranging timber damage at the Menokin Ruin in mind, but applicable to many buildings for in-place supplemental strengthening.

An overview of carbon fiber uses for strengthening individual timbers or floor systems. Epoxy tape can be used to support weakened timbers, but with vacuum-forming carbon fiber cloth can be form-fit to the core of hollow timbers as well.

Carbon Fiber Repair for Historic Buildings, Intro

Stabilization with carbon fiber is a very cost-effective and preservation-oriented option for deteriorated building elements.
