Taşıt Fren Balatalarının Geliştirilmesinde Kullanılan Bitkisel Elyaf İçeren Türleri ve Frenleme Performanslarına Etkileri

Öz

Fren sistemleri, motorlu taşıtlarda güvenliğin sağlanmasında kritik bir rol oynayan, aracın hızını azaltmak veya tamamen durdurmak amacıyla çalışan mekanik ve termal sistemlerdir. Bu sistemlerin en önemli bileşenlerinden biri olan fren balataları, sürtünme yoluyla kinetik enerjiyi ısı enerjisine çevirerek aracın yavaşlamasını sağlar. Geleneksel fren balataları; bağlayıcı reçineler, sürtünme düzenleyici katkılar, dolgu malzemeleri, aşındırıcılar ve lif takviyeleri gibi çeşitli bileşenlerden oluşmaktadır. Son yıllarda, çevresel kaygılar ve insan sağlığı üzerindeki olumsuz etkiler nedeniyle, fren balatalarında kullanılan sentetik veya toksik liflerin yerini alabilecek doğal elyaflara yönelik ilgi artmıştır. Tarımsal atıklar veya yenilenebilir bitkisel kaynaklardan elde edilen doğal lifler; düşük yoğunlukları, biyobozunur yapıları ve yeterli mekanik özellikleri sayesinde sürdürülebilir malzeme alternatifleri arasında öne çıkmaktadır. Doğal liflerin fren balatalarında kullanımı, sadece fren performansını iyileştirmekle kalmayıp aynı zamanda çevresel etkileri azaltarak sürdürülebilirlik hedeflerine katkı sağlamaktadır.

Types of Plant Fibers Used in the Development of Vehicle Brake Pads and Their Effects on Braking Performance

Öz

Brake systems play a critical role in ensuring safety in motor vehicles, operating as mechanical and thermal systems designed to reduce the speed of the vehicle or bring it to a complete stop. One of the most important components of these systems is the brake pad, which slows down the vehicle by converting kinetic energy into heat energy through friction. Conventional brake pads are composed of various ingredients, including binder resins, friction modifiers, fillers, abrasives, and fiber reinforcements. In recent years, due to environmental concerns and the adverse effects on human health, there has been a growing interest in using natural fibers as alternatives to synthetic or toxic fibers in brake pads. Natural fibers obtained from agricultural waste or renewable plant-based sources stand out as sustainable material alternatives due to their low density, biodegradable nature, and adequate mechanical properties. The use of natural fibers in brake pad applications not only improves braking performance but also contributes to sustainability goals by reducing environmental impact.
