Current use of fossil fuels has raised adverse problems in today’s society. The biggest one of them is the climate change caused by emissions of greenhouse gases. For this reason, renewable energies, or energy flows which are replenished at the same rate as they are used, are needed to reduce carbon emissions in the range of 60-80% by the end of the twenty-first century. [1] Energy used in houses nationwide contributes to 16% of generated greenhouse gas emissions. [3] This large percentage of greenhouse emissions could be reduced by designing and developing energy efficient houses, or net-zero energy houses, such …

Sandwich composites utilize a low density core and relatively stiff face sheets. These structures are ideal for applications that require high compressive strength, high bending stiffness, and very low weight such as aerospace vehicles. However, one problem with sandwich composites is their susceptibility to low velocity impact damage. Low velocity impacts result in both external damage, in the form of dents, and internal damage, in the form of core crushing, face sheet delaminations (two adjacent plies separating from one another), fiber fractures and matrix cracks. In general, it is assumed that visibly evident damage will be repaired. Barely visible impact …
