A cost-effective lightweight protection technique for explosives transporting container and storage facilities was developed employing surface-mounted rigid PU foam (RPF) plates. Different RPF specimens were prepared with different densities and sand particle reinforcement ratios ranging between 0% (unreinforced) and 30%. Mechanical properties characterisation was conducted to optimise an RPF formulation to be tested under blast loading using different experimental techniques. Explosive scaling laws were utilised to relate indoor blast test results (performed with small explosive charges) to real-life blast scenarios. Small RDX explosive charges were placed and detonated inside RPF …
