Thermal aging effect on mechanical properties of polyamide 6 matrix composites produced by <scp>TFP</scp> and compression molding
Abstract
<jats:title>Abstract</jats:title><jats:sec><jats:label /><jats:p>Tailored Fiber Placement is an innovative manufacturing technique that precisely positions continuous fibers in critical areas of fiber preforms for optimal structural performance. This study focuses on producing glass fiber‐reinforced polyamide composites using TFP technology and compression molding to address the durability concerns of thermoplastic matrix composites in automotive parts. The production process involved a constant temperature of 300°C, 16 bar pressure, and holding times of 270, 300, and 330 s. Short‐term thermal aging cycles were applied to simulate automotive part acclimatization. Tensile and 3‐point bending tests were conducted to evaluate mechanical properties. Statistical analysis using response surface methodology provided insights into the relationship between production parameters and mechanical properties. Differential Scanning Calorimetry characterized the composite material, and macroscopic damage analysis was performed. Results showed a potential 10% decrease in tensile strength due to short‐term thermal aging. Aging had the most significant impact on elastic modulus and tensile strength according to the Pareto chart. Flexural modulus increased, while flexural strength decreased with thermal aging. Holding time had no effect on flexural modulus but reduced flexural strength.</jats:p></jats:sec><jats:sec><jats:title>Highlights</jats:title><jats:p><jats:list list-type="bullet"> <jats:list-item><jats:p>Glass/polyamide composites were produced by compression molding with TFP technology.</jats:p></jats:list-item> <jats:list-item><jats:p>Short‐term thermal aging cycles were applied on the GF‐PA6 composite material.</jats:p></jats:list-item> <jats:list-item><jats:p>Mechanical properties were analyzed statistically according to the RSM.</jats:p></jats:list-item> <jats:list-item><jats:p>TFP technique can assist OEM companies in lowering desired target cost per vehicle.</jats:p></jats:list-item> </jats:list></jats:p></jats:sec>
