Abstract
Karbon/PP(Polipropilen)/epoksi
hibrid kompozitlerin eğilme dayanımı ve yapısal iyileştirme özellikleri
incelenmiştir. Karbon ve PP lifleri, manuel bir dokuma tezgâhında dokunmuştur.
Burada, karbon lifleri yapıya yüksek dayanım kazandırırken, PP lifleri ise
tokluk özelliği sağlamaktadır. İki
farklı yapısal iyileşme prosesi kullanılmıştır. Önerilen iyileşme proseslerinin
etkinliği, hem mekanik hem de mikroskobik olarak değerlendirilmiştir. Sonuçlar,
iyileşmiş kompozitlerin eğilme dayanımlarının, hem 0° hem de 90° doğrultuda
oldukça azaldığını göstermiştir. Presle iyileştirilmiş kompozitlerin artık
eğilme dayanımları, etüvde iyileştirilen kompozitlere kıyasla daha yüksektir.
Bunun nedeni, erimiş PP liflerinin boşlukları basınç altında daha etkili bir
şekilde doldurmasıdır.

Abstract
Bending strength and structural healing properties of
carbon/PP(Polypropylene)/epoxy hybrid composites are investigated. Carbon and
PP fibres are woven in a manual loom in which the carbon fibres provide high
strength while the PP fibres contribute with their high strain in
hybridization. Two different structural
healing processes are used. Effectiveness of the proposed healing processes is
evaluated by both mechanically and microscopically. The results showed that
bending strengths of healed composites incredibly decreased at both 0° and 90° directions.
Residual bending strengths of press-healed composites are higher than that of
oven-healed composites since the molten PP filled the gaps more influentially
under pressure.
