Abstract
One of the major challenges of thermoplastic matrix based composites is to manufacture finished parts both in one shot process and in a reduced time production. For this purpose, two techniques were developed to manufacture eco-friendly composites: one is the stamping using hot and cold airflow and the second one concern a one shot manufacturing of sandwich using infusion process. Then, several quasi-static and dynamic analyses were performed to validate the efficiency of the developed processes and to confirm the good quality of the material.
Highlights
Fibres reinforced composites are increasingly used in aerospace, automotive, marine industries and civil engineering due to their high specific strengths and modulus, stiffness, good corrosion resistance and fatigue properties
The use of synthetic fibre reinforced composites may become a problem from health and environmental point of view
Sandwich structures were produced in one-shot liquid resin infusion process at room temperature, described in a previous work [16]
Summary
Fibres reinforced composites are increasingly used in aerospace, automotive, marine industries and civil engineering due to their high specific strengths and modulus, stiffness, good corrosion resistance and fatigue properties. Thermoplastic composites are widely being studied because they allow the recycling of composite materials - a significant aspect of the end of life management of traditional thermoset composites These composites can be tailored to provide other attractive properties for the automotive and aerospace industrials, such as a good forming ability to process large and complex structural parts [9, 10]. Another review shows that the Roctool company has successfully developed a fast thermal-compression molding process applied to large parts based on thermoplastic composites [13]. This technique consists in heating both the punch and the die and eventually the material by electromagnetic induction current. One way was to investigate a process using hot air flow and the second way was to manufacture bio-sandwichs with one-shot technique using thermoplastic liquid resin
