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 AFRLAFLCMC 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.
