Manufacturing of electroactive morphing carbon fiber/glass fiber/epoxy composite: Process and structural monitoring by FBG sensors

Ablative composites are heat shielding, protective materials that are being used in aerospace industry to protect inner hardware and sensitive devices. The aero dynamic vehicles have to face high stresses, ultra high temperature and adverse conditions of air friction. It is required to develop the materials with light weight and high modulus. EPDM, being heat and ozone attack resistant is the best candidate for the preparation of ablative composites by introducing different heat sinks such as silica, glass fiber, carbon fiber, asbestos, carbon and their combinations have been studied in this work. The prepared materials were tested and it was found that visco elastic behavior of the composites affected by the addition of reinforcing filler (carbon, silica), semi-reinforcing filler (carbon fiber, glass fiber) and non-reinforcing filler (asbestos powder). Mechanical properties tested at different rates, revealed the improvement in tensile strength and % elongation in case of reinforcing and semi-reinforcing fillers but showed adverse effect in case of non-reinforcing fillers. Rheological investigations of these novel composites shows that moony viscosity of the materials containing glass fiber, carbon fiber, silica decreases in the order glass fiber > carbon fiber > silica.

This study uses carbon fiber (CF) and glass fiber (GF) as reinforcement for polylactic acid (PLA) fiber, and their mixtures are melt-blended into PLA/CF/GF composites. Mechanical properties of the composites are evaluated by applying a tensile test, a flexural test, and an impact test, and the dispersion of fibers is observed by using a scanning electron microscopy (SEM). The test results show that the increasing content of CF results in a greater strength in the composites while the increasing content of GF provides the composites with greater modulus. The combination of both CF and GF contributes to a certain level of mechanical strength and also decreases the production costs for the composites.
