Experimental analysis of the warm stamping of metal/thermoplastic polymer nanocomposite laminates

Abstract

The effects of matrix type, temperature, and weight percentage of nanoreinforcement on maximum drawing force and drawing depth have been studied in warm stamping of reinforced metal/nanocomposite laminates.The laminates were composed of two thermoplastic polymers of glass fibersreinforced polypropylene and polyvinyl chloride, two reinforcements of nanoclay and multi-walled carbon nanotubes as the core layer, and aluminum 1050-O as the skin layer. Change of the matrix type from polyvinyl chloride to polypropylene increased the maximum drawing force and decreased the drawing depth. Besides, the drawing depth in most samples was decreased by increasing the weight percentage of the nano reinforcement. Increase of the temperature led to increasing the drawing depth and decreasing the maximum drawing force. Temperature had the greatest effect on the output parameters, especially the drawing depth.

Self‐resistance heating forming and performance analysis of Al/PEEK/CFRP laminates

“…They provide properties of high modulus, high toughness, a no‐cured chemical reaction, short forming time and reprocessability, [ 11–14 ] and are thus suitable for rapid prototyping of large‐scale structural and complex parts by stamping, deep drawing, and other processes. [ 15–17 ]…”

“…They provide properties of high modulus, high toughness, a nocured chemical reaction, short forming time and reprocessability, [11][12][13][14] and are thus suitable for rapid prototyping of large-scale structural and complex parts by stamping, deep drawing, and other processes. [15][16][17] However, the high molding temperature of TP-FMLs leads to long heating and thermoforming cycles, large thermal inertia, and large energy consumption during heating. [18,19] To shorten the heating and thermoforming times, different inner thermal source heating methods, such as microwave heating, [20] electromagnetic induction heating, [21] and self-resistance electric (SRE) heating [22] have been proposed over the years.…”

“…21,22 Metal/composite laminates also give an improvement of fatigue response, resistance to impact loads, corrosion and crack growth. 23 Due to the several advantages, such as thermoformable feature, 24 recyclability, 25 ease of processing and good corrosion resistance, 26 the demand for thermoplastic composites has been growing day by day. Among thermoplastic polymers, polyamides have received great attention thanks to their unique merit like superior characteristics at elevated temperatures.…”
