Abstract
Scope of neat and fibre reinforced polymers (FRP) for load bearing applications. State-of-the-art and trends. Design procedures for neat polymers under sustained, combined, and fatigue loading conditions. Stability and brittle fracture issues. Composition of FRP. Properties of fibre and matrix materials. Processing and design of FRP: laminate and net theory, stability, creep and fatigue behaviour.
Objective
Impart the basics to future mechanical, civil, and materials engineers for the engineering design with neat polymers and fibre reinforced polymers (FRP) for load bearing applications. In parallel to the presentation of the basics many practical applications will be treated in detail.
