Effect of Temperature on Tensile Properties of Electrospun Nanofibre Interleaved Carbon Composites
Polymer Composites, EarlyView.Thermal Durability of Electrospun Nanofibre Interleaved Composites. ABSTRACT Carbon fiber composites are susceptible to brittle damage modes such as matrix cracking and delamination. The inception and propagation of these invisible damages are responsible for loss in load‐bearing capacity and accelerating environmental degradation.
