<div class="section abstract"><div class="htmlview paragraph">Vehicle occupant protection remains a critical concern in the field of crashworthiness technology. When integrated into polymer nanocomposites, natural fibres like sisal offer high strength-to-weight ratio that can contribute to effective energy absorption during collisions. However, these fibers present challenges, such as poor hydrophilicity and moisture retention. This study employs compression molding techniques create hybrid composites fibers, epoxy, titanium oxide nano fillers. We particularly investigate how fiber orientation concentration fillers optimize mechanical thermal properties, thereby enhancing features. Our findings demonstrate incorporation epoxy matrix significantly influence composite's characteristics. Composites reinforced with continuous exhibited an 11%-18% increase impact strength compared those randomized fibers. Additionally, 3% improvement hardness was recorded for same comparison. In context fillers, 8 wt.% added woven resulted peak tensile 81.25 MPa. 6 composite reached 31.58 J showed enhanced properties. These improvements properties are crucial dispersion, key factors vehicular crashes. Interestingly, density notably lower 2 wt% TiO<sub>2</sub> 4 TiO<sub>2</sub>, factor attributed high-density nature nanoparticles.</div></div>

<div class="section abstract"><div class="htmlview paragraph">This research was conducted with the aim of exploring usage advanced lightweight materials such as aluminum matrix composite and aramid fiber reinforcement polymer for increased structural integrity hood an automotive vehicle. The sector is moving toward because need to enhance fuel efficiency, importance reducing environmental impact, ensure safety new-generation automobiles. While traditional steel might be very rigid durable, they also add huge weight overall vehicle design. Consequently, these vehicles become more inefficient, which could lead higher emissions pollution. two chosen this are promising, considering that both characterized by high specific strength impact resistance capabilities. low added bonus. AMC manufactured consolidating ceramic or metallic components, AFRP employs fibers in a matrix. test performed evaluate suitability said purpose include tests on resistance, tensile strength, hardness. were tested concerning standards Charpy test, universal testing machines, Vickers scale. findings produced differing results materials. demonstrated average 76 kJ/m<sup>2</sup>, 402 MPa, hardness 122 HV.

<div class="section abstract"><div class="htmlview paragraph">This research investigates the development of a heat pipe exchanger coated with graphene for cooling and purification automobile exhausts. The directly affects performance engine because proper dissipation transfer can improve performance, reduce fuel consumption, decrease emission. Moreover, this effect is much more noticeable on pipes enhanced thermal conductivity mechanical properties films. A null emitted by internal combustion engines was used in experimental setup to test efficiency, efficiency newly designed in-house exhaust simulation system where new were inserted. results experiment show that have very high as calculated be around 85%. Furthermore, temperature over surfaces measured at 350°C, which means 70% gas cooled. approximately nitrogen oxides, particulate matter, carbon monoxide, hydrocarbons, all are harmful pollutants produced engines. Since these substances reduced about 70%, use coats demonstrate effectiveness feasibility such emission reduction. Consequently, graphene-coated recognized highly effective device enhancing reducing promoting efficient transportation lower emissions.</div></div>

<div class="section abstract"><div class="htmlview paragraph">This research aimed to explore the integration of Virtual reality technology in ergonomically testing automotive interior designs. This objective was at ensuring that such could be used ameliorate user comfort through controlled simulations. Existing ergonomic methods are often limited when it comes recreating actual driving situations and quickly repeating design improvements. VR as a solution because its tested simulation can provide users with real experience driving. The observed while they asked for their feedback. For this research, an interactive environment imitating 10-minute-long trip traffic changing road conditions created. It populated by ten users, concatenated equally men women, both aged 20-35, representing approximate demographics workers production industry. Participants were use assessed metrics, which included subjective rating, control reachability, visibility rating overall within simulation. well-received demands research. Its uses found comfortable easy use, average metrics 7.5, 8.0, respectively comfort, controls, visibility. averaged 7.8. information obtained proves environments effectively simulate cars ergonomics potentially revolutionary technology, accelerating development early detection mistakes facilitating iterative improvements subsequent iterations.</div></div>
