Interpretive Summary: Composite wood panels (CWPs) are a type of engineered wood composites (particleboard, medium-density fiberboard, high-density fiberboard, oriented strand board, plywood) employed in building products. Over the past few years, we have been developing biobased adhesives to bind with wood to fabricate composite wood panels. In this study we performed dynamic impact tests, similar to explosions on CWPs developed using biobased adhesives made from distillers dried grains and solubles (DDGS). The studies determined that CWPs formed with these biobased adhesives shattered in a powdered form which would lessen human injury compared to commercial CWPs.Currently, the global wood panel market is worth $91billion, and the USA share of the wood panel market is valued at $12 billion, and there is market value of replacing environmentally unfriendly adhesive chemicals with biobased adhesives.

Technical Abstract: The dynamic behavior of novel bio-based composite wood panels (CWPs), consisting of a Distiller’s Dried Grains & Soluble (DDGS) flour adhesive binding to a wood filler/reinforcement, were subjected to various high strain-rate compression loading is reported. Specimens of DDGS-Paulownia wood (PW) or DDGS-Pinewood (Pine) composites made using DDGS with volume fractions of 10%, 15%, 25%, and 50% were tested at high strain-rate on a modified compression Split Hopkinson Pressure Bar (SHPB). Both DDGS-PW and DDGS-Pine composites displayed strain-rate sensitivity, with DDGS-PW having 25% volume fraction showing highest ultimate compressive strength of 655 MPa at ~1600/s. The 90%-PW was found to have highest specific energy exhibiting 19.24 kJ/kg at ~1600/s when loaded in dynamic compression. CWPs constructed of DDGS-PW had higher strength and energy absorption than DDGS-Pine with the exception of 50% DDGS composites.
