“…Setiap material punya kelebihan dan kekurangan dari berbagai segi karenanya beberapa peneliti melakukan kajian mengenai kemungkinan dilakukan kombinasi dua jenis material seperti baja dan FRP bahkan material sandwich yang sekarang sementara menarik perhatian para perekayasa material [9], [10]. Bahkan material FRP digunakan juga untuk memperkuat penyambungan dua jenis material berbeda [11].…”

Salah satu sumber getaran pada kapal adalah akibat kerja mesin induk. Material struktur menjadi salah satu penentu besarnya amplitudo yang terjadi. Kapal monohull dengan penggunaan 3 mesin menjadi objek dari penelitian ini. Getaran pada dinding di ruang penumpang menjadi penting ketika amplitudo yang terjadi mengganggu penumpang di dalamnya. Karakteristik getaran perlu diketahui agar dapat dicarikan solusi untuk mengatasinya. Pengukuran getaran langsung di kapal menggunakan vibrometer dan dilanjutkan dengan menggunakan simulasi hingga diperoleh karakteristik getaran pada dinding kapal ini. Hasil pengukuran di lapangan menunjukkan angka amplitudo di atas 0,2 mm melebihi batas yang diijinkan yaitu 0,02 mm. Diperlukan simulasi untuk menggambarkan distribusi getaran pada dinding kapal. Hal ini untuk mempermudah proses analisa pola distribusi getaran . Hasil simulasi pada dinding kapal menunjukkan bahwa getaran dalam arah vertikal mempunyai nilai amplitudo yang lebih besar dan frekuensi lebih rendah dibandingkan arah getaran horisontal. Hal ini mengindikasikan konstruksi dalam keadaan buruk jika frekuensi natural dari sistem tersebut mendekati nilai frekuensi eksitasi akibat operasional mesin. Getaran yang diteruskan dari sumber getaran tidak teredam dengan baik dalam arah vertikal. Hal ini ditunjukkan dengan besarnya nilai amplitudo yang mencapai 10 kali lebih besar dari amplitudo arah getaran horisontal. Penelitian ini menunjukkan diperlukan peredam pada bagian dinding kapal agar getaran dalam arah vertikal dapat dikurangi. Adapun cara meredam getaran dapat dilakukan dengan berbagai cara. Solusi untuk mengurangi getaran ini menjadi peluang untuk dilakukan penelitian lainnya.

“…Carbon fiber-reinforced polymers (CFRPs) have historically been highly favored lightweight materials in the automotive industry [1][2][3][4][5]. Offering excellent mechanical properties at a comparatively low weight compared to traditional metals [6][7][8], CFRP has played a pivotal role in reducing the weight of automobiles, subsequently lowering greenhouse gas emissions and fossil energy consumption [9].…”

The extensive use of carbon fiber-reinforced composites and aluminum alloys represents the highest level of automotive body-in-white lightweighting. The effective and secure joining of these heterogeneous materials remains a prominent and actively researched topic within the scientific community. Among various joining techniques, clinching has emerged as a particularly cost-effective solution, experiencing significant advancements. However, the application of clinching is severely limited by the properties of the joining materials. In this work, various clinching processes for the joining of composites and aluminum alloys reported in recent research are described in detail according to three broad categories based on the principle of technological improvement. By scrutinizing current clinching technologies, a forward-looking perspective is presented for the future evolution of clinching technology in terms of composite–aluminum joints, encompassing aspects of tool design, process analysis, and the enhancement of joint quality. This work provides an overview of current research on clinching of CFRP and aluminum and serves as a reference for the further development of clinching processes.

“…9 Another process, the mechanical clinching process is used to make a metal-polymer hybrid joint by applying forming force so that materials are plastically deformed and interlocked between materials. 10,[11][12][13] FSW was invented by Thomas et al 14 back in 1991. At that time, it was considered the only viable option for welding Aluminium alloys (mainly AA2xxx and AA7xxx series alloys) which are difficult to weld or were considered unweldable.…”

In this research work, a butt joint between acrylonitrile butadiene styrene (ABS) sheets was made using Friction stir welding (FSW). Polymers such as ABS have great potential to be used as body parts in automotive industries because of their high strength-to-weight ratio. In the aerospace industry, polymers are preferred over metals as they can retain their properties at low temperatures and their light weight reduces fuel consumption. The objective of this research work was to investigate mechanical properties and defect characterization in weldments. Maximum weld strength achieved was 19.4 MPa which is 61% of the base material at a rotational speed of 224 r/min, travel speed of 50 mm/min, external heating temperature of 45°C, and shoulder diameter of 16 mm. The images of macro and microstructure from an optical microscope and scanning electron microscope, respectively, showed that in FSW of ABS polymer defects were mainly formed on the retreating side of the weld nugget, unlike FSW of metals having it on the advancing side. Only two experiments out of L18 experiments showed tunneling defect, i.e., Experiment no. 8 and Experiment no. 10 and four experiments showed undercutting defect, i.e., Experiment no. 6, 9, 12, and 18. By performing the Vickers microhardness test it was observed that the hardest region formed in and around the weld nugget.
