Compressive strength reduction due to fibre waviness is a key concern in composite structures. Specimens with fibre misalignments representative of those that can occur at ply drops and resin rich areas in components were manufactured by incorporating either two or 10 discontinuous plies oriented either in 0°..
Failure analysis is the process of collecting and analyzing data to determine the cause of a failure, often with the goal of determining corrective actions or liability. It is an important discipline in many branches of manufacturing industry, such as the electronics industry, where it is a vital tool used in the development of new..
An experimental study was carried out to investigate the effect of temperature on the mechanical properties and the fracture mechanism of woodplastic composites (WPCs) under tension. The specimens were prepared via injection molding of various weight fractions of pine wood particles and high-density polyethylene..
