Cam Elyaf ile Güçlendirilmiş Yüksek Performanslı İleri Polimerlerin Analizi

Günümüz otomobil ve elektronik endüstrisindeki hızlı gelişmeler, daha yüksek mukavemetli ve daha hafif ağırlığa sahip yüksek performanslı mühendislik polimerlerinin kullanılmasını gerekli kılmıştır. Bu çalışma, %40 cam elyaf takviyeli ve %30 cam elyaf takviyeli iki yüksek performanslı mühendislik polimerinin mekanik davranışlarını, hacimsel büzülmelerini ve reolojik özelliklerini karşılaştırmaya ve değerlendirmeye odaklanmıştır. Çekme çubukları ve dikdörtgen çubuk tipi örnekler sırasıyla üç işlem koşulu altında enjekte edildi. Enjeksiyon testlerinden çekme dayanımı, gerinim (%), darbe dayanımı, hacimsel büzülme, erime akış indeksi ve yoğunluk değerleri elde edildi. Sonuçlar, cam elyafı miktarının bir sonucu olarak% 40 cam elyaf takviyeli PPS polimerinin% 30 cam elyaf takviyeli PEI polimerinden daha iyi olduğunu ortaya koymuştur. Ayrıca, s hrinkage ile ociated olarak en iyi boyutsal stabilite, PPS polimerinin yarı kristalin doğası nedeniyle elde edilmiştir. Son olarak, bu çalışma, cam elyafı eklenmiş yüksek performanslı gelişmiş polimerlerin mühendislik uygulamalarında büyük potansiyel gösterdiğini ve elektronik ve otomotivin geliştirilmesi ve uygulanması için iyi bir potansiyel sağlayabileceğini kanıtlamıştır.

Analysis of High-Performance Advanced Polymers Reinforced with Glass Fiber

Rapid developments in today's automobile and electronics industry have made it necessary to use high-performance engineering polymers with higher strength and lighter weight. This present study focused on comparing and evaluating the mechanical behavior, volumetric shrinkage and rheological characteristics of two high performance engineering polymers 40% glass fiber reinforced and 30% glass fiber reinforced. Tensile rods and rectangular bar-type specimens were injected, under three process conditions, respectively. The values of tensile strength, strain (%), impact strength, volumetric shrinkage, melt flow index and density were obtained from the injection tests. The results exposed that the mechanical properties of 40 % glass fiber reinforced PPS polymer is better than those of 30% glass fiber reinforced PEI polymer as a result of amount of glass fiber. Moreover, the best dimensional stability associated with shrinkage has achieved due to the semi-crystalline nature of the PPS polymer. Finally, this study has proven that glass fiber added high performance advanced polymers display great potential in engineering applications, and may provide a good potential for the development and application of electronics and automotive.
