TERMOFORM YÖNTEMİ İLE TERMOPLASTİK KOMPOZİT MALZEME ÜRETİMİNİN İNCELENMESİ

Öz

Kompozit malzemeler, farklı fiziksel ve kimyasal özelliklere sahip iki veya daha fazla malzemenin bir araya getirilmesiyle elde edilen çok fazlı yapılardır. Bu yapıların temel amacı, bileşenlerin avantajlı yönlerini bir arada kullanarak üstün mekanik, termal ve yapısal özellikler sağlamaktır. Polimer matrisli kompozitler; düşük yoğunluk, yüksek özgül mukavemet ve kolay işlenebilirlikleri sayesinde özellikle uzay-havacılık, otomotiv ve savunma sanayiinde yaygın kullanım alanı bulmaktadır. Bu grupta yer alan termoplastik matrisli kompozitler, termoset esaslı sistemlere kıyasla daha kısa çevrim süresi, geri dönüştürülebilirlik, uzun raf ömrü, yüksek darbe dayanımı ve çevreye duyarlı üretim süreçleriyle öne çıkmaktadır. Endüstride hızlı üretim ihtiyacını karşılayan ve karmaşık geometrilere uyum sağlayabilen termoform yöntemi, termoplastik kompozitlerin şekillendirilmesinde önemli bir teknik olarak dikkat çekmektedir. Termoform süreci; ön ısıtma, şekil verme ve kontrollü soğutma aşamalarından oluşmakta olup, sıcaklık, basınç ve süre gibi işlem parametreleri ürün kalitesi ve mekanik performans üzerinde doğrudan etkilidir. Bu çalışmada termoplastik kompozit malzemelerin endüstriyel uygulamalarda avantajları, kullanım alanları ve özellikle termoform şekillendirme süreci ayrıntılı biçimde ele alınarak literatürdeki güncel gelişmeler sistematik biçimde değerlendirilmiştir. Çalışma, termoform termoplastik kompozit üretiminde işlem parametreleri, üretim hataları ve optimizasyon stratejilerini karşılaştırmalı olarak analiz etmekte ve literatürdeki mevcut çalışmalar arasındaki temel eğilimleri ortaya koymaktadır.

INVESTIGATION OF THERMOPLASTIC COMPOSITE MATERIAL PRODUCTION BY THERMOFORMING METHOD

Öz

Composite materials are multi-phase structures obtained by combining two or more materials with different physical and chemical properties. The main purpose of these structures is to utilize the advantageous aspects of each constituent together to achieve superior mechanical, thermal, and structural properties. Polymer matrix composites, owing to their low density, high specific strength, and ease of processing, are widely used in aerospace, automotive, and defense industries. Within this group, thermoplastic matrix composites stand out over thermoset systems with their shorter cycle time, recyclability, long shelf life, high impact resistance, and environmentally friendly manufacturing processes. The thermoforming method, which meets industrial demands for rapid production and adaptability to complex geometries, has become a prominent technique for shaping thermoplastic composites. The thermoforming process consists of three main stages—preheating, forming, and controlled cooling—and process parameters such as temperature, pressure, and time have a direct influence on product quality and mechanical performance. In this study, the advantages, application areas, and particularly the thermoforming process of thermoplastic composite materials are examined in detail, and recent developments in the literature are systematically evaluated. The study comparatively analyzes the process parameters, manufacturing defects, and optimization strategies in thermoformed thermoplastic composites, revealing the key trends among current research studies.
