<p>Kendaran transportasi dituntut dengan spesifikasi produk yang ringan, kuat, dan ramah terhadap lingkungan, sehingga dapat mengurangi konsumsi energi dan emisi CO<sub>2</sub>. Inovasi pada konstruksi sambungan tanpa proses permesinan menjadi terobosan baru dalam proses penyambungan beda material seperti aluminium-komposit. Material adherend komposit digunakan jenis penguat serat alam cocofiber yang memiliki sifat ramah lingkungan dan material aluminium memiliki sifat tahan korosi yang baik dan bobot ringan, sehingga cocok untuk digunakan pada panel dinding transportasi. Tujuan penelitian ini untuk menganalisis pengaruh penggunaan perekat campuran sikahyflex (SF) - epoksi (EP) terhadap kekuatan tarik geser pada sambungan material aluminium 5083–komposit cocofiber. Selain itu, penelitian ini sebagai inovasi baru dan pengembangan penggunaan material perekat campuran dan material adherend yang tahan korosi dan ramah lingkungan dengan penggunaan komposit serat alam cocofiber. Manfaat penelitian ini secara langsung dapat meningkatkan penggunaan dan nilai ekonomis cocofiber yang murah. Selain itu, dapat menghasilkan material maju yang kuat, murah, ringan, dan tahan terhadap lingkungan. Material perekat menggunakan variasi perekat campuran 10% SF : 90% EP, 20% SF : 80% EP, 30% SF : 70% EP, dan 40% SF : 60% EP dengan ketebalan perekat 0,2 mm. Material adherend menggunakan aluminium 5083 dan komposit cocofiber dengan perlakuan kekasaran sandpapering grade #60, #80, dan #150. Komposit cocofiber dibuat mengacu pada standar ASTM D790 dan sambungan SLJ mengacu pada standar ASTM D1002. Hasil pengujian tarik geser pada SLJ terjadi peningkatan dengan penambahan perekat sikahyflex dan perlakuan kekasaran sandpapering grade #150 . Kekuatan tarik geser tertinggi pada variasi 40% SF : 60% EP sebesar 2,42 MPa. Peningkatan grade sandpapering menurunkan surface roughness yang membentuk pola irregularities pada permukaan adherend, sehingga meningkatakan mechanical interlocking adherend dengan perekat campuran. Mode kegagalan terjadi adhesive dan thin layer cohesive failure mode. Pengamatan scanning electron microscope menunjukkan terjadinya void menyebabkan cracking adhesive dan terlepasnya fiber yang menempel pada perekat campuran.</p>

“…[5][6][7][8] Current investigations of hybrid joints have concentrated on the influence of parameters on the fatigue behavior, including design parameters, [9][10][11] process parameters, [12][13][14][15] and environmental factors. [16][17][18] It is noteworthy that the self-heating effect occurs as composite structures are loaded cyclically due to frictional heating and viscoelastic energy dissipation, which, in turn, significantly speeds up the structural degradation. There have been several reports on the study of the self-heating effect in CFRP composites, including the accumulation of fatigue damage caused by the self-heating effect at different scales and the thermal conductive material or cooling schemes to weaken the selfheating effect.…”

The self‐heating‐induced temperature rise in the adhesive layer under fatigue loading plays a significant role in influencing the fatigue behavior of riveted‐bonded hybrid joints in aluminum‐carbon fiber reinforced polymer composite structures. This study aims to investigate the impact of the self‐heating effect on the fatigue life of such hybrid joints. Experimental analysis was conducted to explore the interrelationships between temperature evolution and fatigue behavior at varying frequencies, adhesive thicknesses, and loading levels. Additionally, a theoretical model for predicting self‐heating temperature rise in hybrid joints with different parameters was developed. Results show that the self‐heating effect is notably affected by loading frequency, loading level, and adhesive thickness. The theoretical model accurately captures temperature variations and predicts critical frequencies for hybrid joints under different loading levels, which are identified as 10, 8, 3, and 1 Hz for loading levels of 35%, 40%, 50%, and 60%, respectively. Critical adhesive thicknesses ranging from 0.5 to 1 mm were also determined. Furthermore, the study predicts the fatigue life at specific self‐heating temperatures with an average error within 4%, offering valuable theoretical insights for evaluating the fatigue safety performance of hybrid joints and facilitating optimization strategies.Highlights The interrelationship between the self‐heating effect and fatigue behavior was revealed. Quantitative influences of main process parameters on the self‐heating effect were discussed. A self‐heating temperature rise model considering process parameters was developed. The critical frequency and adhesive thickness of the hybrid joint were determined.

Fiber-reinforced laminated composite is often used in harsh environments that may affect their static stability and long-term durability as well as residual strength. In this study, the effect of heavy chemical environments such as acid and alkaline and retaining time for these environments on flexural strength and flexural fatigue behavior of carbon/epoxy laminated composites were investigated. In this context, carbon/epoxy was retained into an acidic and alkaline solution having 5%, 15%, and 25% concentration by weight for 1–4 months. Fatigue behavior of carbon/epoxy was determined under dynamic flexural load, which corresponds to 80%, 70%, 60%, 50%, and 40% of static three-point bending strength of the test sample. SEM image of damaged specimens was taken to describe the failure mechanism of damage which occurs after fatigue. Also, to better understand environmental condition on the fatigue life, results were compared with results of carbon/epoxy laminated composites, which were not retained into any environments (unretained). The test results showed that the solution type, solution concentration, and retaining time caused noticeable changes in the static and dynamic strengths of carbon/epoxy laminated composites.
