    摘要: A method for inserting an insert into a hole in a composite material made from a plurality of carbon fiber layers suspended in a resin material includes lowering a temperature of the insert to a reduced temperature at which a coefficient of thermal expansion of a material of the insert causes the insert to contract to a first perimeter, inserting the insert at the reduced temperature into the hole, and permitting the temperature of the insert to increase from the reduced temperature to an operational temperature. At the operational temperature, the insert expands to a second perimeter so that the insert is retained within the composite material due to an interference between the insert and the composite material. The interference transfers a structural load from the insert to the composite material and results in damage to the composite material if the insert is dislodged at the operational temperature.
