Thermoplastic composites are preferred over their thermosetting counterparts due to their high toughness, fast manufacturing cycle, and ease of recycling. Another advantage is the variety of techniques available to join these thermoplastic composites. This paper analyzes the static and dynamic behavior of glass fiber‐reinforced thermoplastic composite joints produced using different joining techniques. The composite materials were fabricated by compression molding of glass fabric and polypropylene (PP) matrix. These composites were joined using approaches like riveting, adhesive bonding, resistance welding, and hybrid joining techniques. The performance of these joints was analyzed under static and dynamic tensile loads. During the static test, the resistance welded joints showed superior performance as compared to the other joining techniques. The highest load of 2183 N was taken by the resistance welded sample, while the least (358 N) was taken by the mechanical joint. In dynamic testing, the resistance welded joints showed the least variation in the modulus during the dynamic test, showing a higher modulus as compared to the other joining techniques. The highest number of cycles to fail the joint was obtained for the mechanical joint, that is, 40,100, while a similar value was exhibited by the resistance welded joint (39,674). The static and dynamic test results showed resistance welding to be a promising approach for joining thermoplastic composites.

“…Among these techniques, laser transmission welding (LTW) is one of the most useful methods for joining thermoplastic materials, particularly for thin parts. 4,5 In particular, laser welding is becoming an attractive and economically advantageous joining technique in the automotive industry due to much superiority over conventional welding techniques, such as non-contact and single-side access welding, low process cost, and the suitability of automation. [6][7][8][9][10] The LTW uses a laser beam to connect the surfaces of two materials having different optical characteristics.…”

Recently, the usage of laser transmission welding (LTW) technology in the automotive industry has been rising for joining thermoplastic parts regarding its superior properties in comparison to other welding technologies. However, specifying the process parameters is a crucial step to obtain satisfactory welding quality for the vehicle parts. In this context, this paper addresses the LTW process of Polimetil metakrilat (PMMA) to Akrilonitril bütadien stiren (ABS) materials for the production of taillights in an automotive company and proposes a new multi-response Taguchi-Based TOPSIS (Technique for Order of Preference by Similarity to Ideal Solution) method to optimize machining parameters in the laser welding process. In the proposed solution methodology, the main effects of the parameters on different outputs are identified by using the [Formula: see text] orthogonal array of the Taguchi method. Regarding the best parameter set for each output, the best parameter set for multi-response is identified by using the TOPSIS method, in which alternatives are evaluated through the interrelated quality measures. To optimize welding process in taillight production, PMMA and ABS samples with the dimensions of [Formula: see text] in width, [Formula: see text] in length, and [Formula: see text] in thickness are used in the experiments. The samples are welded by using LPKF Twinweld 3D 6000® laser welding machine. For the welding process, laser power, welding speed, and pressure force are taken into account as the input parameters to optimize three responses: weld strength, breaking strain, and weld width. To identify the best process parameter values, the Taguchi Method is initially employed to calculate the main effects of LTW parameters for each output. Then, the TOPSIS method is carried out to evaluate a number of alternative parameter sets generated through the Taguchi results. As a consequence of the TOPSIS ranking scores, the best parameter set that jointly optimizes three outputs of the LTW process is identified for the taillight production as [Formula: see text] power, [Formula: see text] speed, and [Formula: see text] pressure force. Based on the conducted experiments, this parameter setting achieves the highest weld strength, breaking strain level, and above-average weld width. The results of the experiments show that the proposed methodology is capable of optimizing LTW parameters for a multi-response with fewer experiments in the joining of plastic vehicle parts.

“…Fibre reinforced composites are now used for emerging structural application areas such as aerospace, automotive, wind turbine, defense area, marines, civil engineering and leisure equipment as replacements for conventional metallic materials [ 1 , 2 , 3 , 4 , 5 ]. Glass and carbon fibres are the two most common reinforcing components which are used in fibre reinforced plastic (FRP) composites.…”

Composites are macroscopic combinations of chemically dissimilar materials preferred for new high-tech applications where mechanical performance is an area of interest. Mechanical apprehensions chiefly include tensile, creep, and fatigue loadings; each loading comprises different modes. Fatigue is cyclic loading correlated with stress amplitude and the number of cycles while defining the performance of a material. Composite materials are subject to various modes of fatigue loading during service life. Such loadings cause micro invisible to severe visible damage affecting the material’s performance. Mode I fatigue crack propagates via opening lamina governing a visible tear. Recently, there has been an increasing concern about finding new ways to reduce delamination failure, a life-reducing aspect of composites. This review focuses on mode I fatigue behaviours of various preforms and factors determining failures considering different reinforcements with respect to fibres and matrix failures. Numerical modelling methods for life prediction of composites while subjected to fatigue loading are reviewed. Testing techniques used to verify the fatigue performance of composite under mode I load are also given. Approaches for composites’ life enhancement against mode I fatigue loading have also been summarized, which could aid in developing a well-rounded understanding of mode I fatigue behaviours of composites and thus help engineers to design composites with higher interlaminar strength.
