Demonstration and Validation of Uncured, Scrap Composite (Prepreg) Reuse, F-35 Composite Manufacturing

Abstract

Feasibility of the Direct Recycling (DR) method of reusing waste, uncured composite prepregs was validated. High rates of fabrication via DR and good to excellent quality of the composites were able to satisfy the requirements of several different reuse applications achieving the 1135 lbs. of waste reductions and $108k of cost savings shown in Table 1 and Table 3 (167 lbs supported AFRL/AFLCMC efforts). DR methods use existing facilities, materials and training reducing startup barriers and achieved 85% to 100% of nominal properties with the economically recyclable feedstocks. While recycling is still only 20% of the waste stream, payback for this work is now estimated to be approx.1.5 years.
