Provided are splices, comprising honeycomb cores and adhesive layers with tie clips supporting the honeycomb cores. Also provided are methods of forming such splices. Each tie clip includes two legs and a bridging portion joining the legs. When forming a splice, an adhesive layer is positioned between two honeycomb cores. One leg of the tie clip is inserted into the full cell of one honeycomb core, while the other leg is inserted into the full cell of the other honeycomb core. The bridging portion extends across the adhesive layer. While curing the adhesive layer, the tie clip supports the honeycomb cores with respect to each other and maintains their orientation. The tie clip becomes a part of the splice. The tie clip may be buried in the honeycomb cores without extending above the first face of the splice.

Thrust reverser inner wall structure comprising a thermally conductive nonmetallic carbon pitch fiber honeycomb core sandwiched between a top and bottom layer. The core is adhered by a reticulated layer of adhesive to a perforated carbon fiber top layer, and adhered to a base layer of nonmetallic, nonperforated carbon fiber reinforced fabric.
