“…Very few studies on QSI or LVI properties were reported on thermoplastic composites, for instance, glass-reinforced polypropylene (GFPP). Impact performance of GFPP, specifically under repeated impact loads, was found to be better than thermoset-based composites, e.g., glass-reinforced epoxy [20]. PP is one of the most popular thermoplastic matrices used for making thermoplasticbased composites.…”

The use of thermoplastic matrix was known to improve the impact properties of laminated composites. However, different ductility levels can exist in a single family of thermoplastic matrix, and this may consequently modify the damage phenomenology of thermoplastic composites. This paper focuses on the effect of matrix ductility on the out-of-plane properties of thermoplastic composites, which was studied through quasi-static indentation (QSI) test that may represent impact problem albeit the speed difference. We evaluated continuous glass-fiber reinforced polypropylene thermoplastic composites (GFPP), and selected homopolymer PP and copolymer PP that represent ductile and less ductile matrices, respectively. Several cross-ply laminates were selected to study the influence of ply thicknesses and relative orientation of interfaces on QSI properties of GFPP. It is expected that GFPP with ductile matrix improves energy absorption of GFPP. However, the damage mechanism is completely different between GFPP with ductile and GFPP with less ductile matrices. GFPP with ductile matrix exhibits smaller damage zone in comparison to the one with less ductile matrix. Higher matrix ductility inhibits the growth of ply cracking along the fiber, and this causes the limited size of delamination. The stacking sequence poses more influence on less ductile composites rather than the ductile one.

“…To make enhancement, the glass fiber (GF) is usually introduced into polymers . It is well known that the addition of GF into PP can result in changes in morphology and crystallization behavior at the interface, tuning the mechanical properties of composites as a result. Thomason has found that tensile strength of the GF reinforced polypropylene laminates, prepared using a wet deposition method, and increased with increasing fiber concentration or fiber length.…”

Three-layer pipe has many advantages over single layer one, especially for the pipe of glass fiber (GF) reinforced materials. But the hoop strength of the pipe produced via convention extrusion is poor because GFs orient along axial direction. In this work, a self-designed rotation extrusion system was adopted to extrude GF reinforced three-layer polypropylene random copolymer (PPR) pipe, in which a hoop shear field was applied to the polymer matrix and fibers in the middle layer. The structure and performance of pipes were investigated via scanning electronic microscope (SEM) and synchrotron two-dimensional wide-angel X-ray diffraction (2D-WAXD). Due to the hoop shear field, the orientation of GFs in middle layer deviated from axial direction. As a result, PPR pipes with enhanced hoop tensile strength were obtained. Because of the three-layer structure and the production process, the molecular chains of middle layer did not emerge distinct orientation after rotation shear, as shown in 2D-WAXD and SEM experimental results. This three-layer pipe rotation extrusion system offers a novel method for the modification of pipes in manufacture industry.

“…Sıcaklık etkisinin yanı sıra, uygulamada karşılaşılabilecek darbe dayanımları göz önünde bulundurulduğunda, benzer elyaf takviyeli termoset kompozitlerde termoplastik kompozitlere kıyasla daha fazla delaminasyon meydana geldiği gözlemlenmiştir. Bu sebeple, aynı elyaf takviyeli fakat ayrı matrise (termoset ve termoplastik) sahip kompozitlerin düşük hızlı darbe davranışı yer değiştirme açısından karşılaştırıldığında, termoplastik kompozitlerin daha iyi darbe performansı sergilediği görülmüştür [7,8].…”

Bu çalışmada, uzun cam elyaf takviyeli polipropilen granüllerden oluşan termoplastik kompozitlerin düşük hızlı darbe davranışları deneysel olarak incelenmiştir. Bu kompozitlerin düşük hızlı darbe davranışını iyileştirmek amacıyla cam elyaf takviyeli polipropilen kompozit prepregler kullanılarak sandviç yapıda yeni bir dizilime sahip kompozitler üretilmiştir. Kalınlığın ve sıcaklığın düşük hızlı darbe davranışına olan etkilerini incelemek amacıyla 4 ve 6mm kalınlığa sahip kompozitlerin oda sıcaklığında ve 50˚C'de deneyleri gerçekleştirilmiştir. Elde edilen sonuçlara göre, iki farklı dizilime sahip kompozitlerin kalınlığın artmasıyla maksimum temas kuvvetinin arttığı, sıcaklığın yükselmesiyle ise düştüğü gözlemlenmiştir.
