“…Yüksek performanslı polietilen lifleri de taşımacılık tekstillerinde özellikle de deniz taşıtlarında geniş bir kullanıma sahiptir [5,12,33,43,62]. Aşırı sağlamlığı, hidrofob yapısı ve hafifliği sayesinde ip, halat ya da urgan [12,21,36,43,120] olarak hem kara hem de deniz taşıtlarında tercih edilen bir hammadde haline gelen HPPE lifleri aynı zamanda derin sulardaki çalışmalarda da başarıyla kullanılmaktadır [5,12,17,44]. Bunun en yakın örneği geçtiğimiz yıllarda İtalya kıyılarında batan seyahat gemisinin deniz altından çıkartılması işlemidir.…”

ÖZYüksek performanslı polietilen (HPPE) lifleri yüksek mukavemet ve elastisite modülünün yanında düşük yoğunlukları ve yüksek mekanik özellikleri ile üstün performans sergilemektedirler. Genellikle jelden lif çekim yöntemi kullanılarak üretilen HPPE lifleri yoğunluklarının düşük, sürtünme ve yorulma dayanımlarının yüksek olmalarının yanı sıra kimyasal maddelerin çoğuna da dayanıklıdırlar. 1 g/cm 3 'ün altındaki yoğunluğu ile su üzerinde yüzebilen bu lifler, yüksek mekanik özellikleriyle suya ve neme dayanıklılığı bir arada bulundurması sayesinde denizciliğin birçok alanında tercih edilen bir malzeme haline gelmiştir. Ayrıca, bu liflerin enerji absorbsiyonunun yüksek olması balistik ürünlerde kullanımını da sağlamaktadır. Erime sıcaklıklarının düşük olması kullanım alanlarını sınırlasa da, günümüzde medikal, koruyucu, taşıma ya da spor teknik tekstilleri başta olmak üzere neredeyse teknik tekstillerin tüm alanlarında kullanımlarına rastlamak mümkündür.Anahtar kelimeler: Yüksek performanslı lif, yüksek mukavemetli lif, yüksek performanslı polietilen lifi, yüksek mukavemetli polietilen lifi, yüksek modüllü polietilen lifi, ultra yüksek molekül ağırlıklı polietilen lifi I. GİRİŞTekstil endüstrisi içerisinde teknik tekstilin önemi her geçen gün daha da artmaktadır. İleri teknoloji ile üretilen, üstün performans özelliklerine sahip lifler de bu nedenle büyük önem taşımaktadır. Yüksek performans lifleri olarak da bilinen bu lifler, sahip oldukları yüksek mukavemet, yüksek kimyasal dayanım, aleve dayanıklılık gibi birçok özellikleri ile konvansiyonel liflerden ayrılarak öne çıkmaktadır. Kopma mukavemetleri genellikle 20g/denye (2,2GPa)'den, elastisite modülleri de genellikle 500g/denye (50GPa)'den yüksek olan [1] yüksek performans lifleri genellikle fark yaratan özelliklerine ve nihai kullanım alanlarına göre ısıya dayanıklı lifler, yüksek mukavemetli lifler ve kimyasallara dayanıklı lifler olarak üç kategoride incelenmektedir. Bu sınıflandırma her ne kadar kesin olmasa da liflerin incelenmesinde yardımcı olmaktadır [2][3][4].Yüksek mukavemetli yüksek performans lifleri sınıfında incelenen yüksek mukavemetli, yüksek elastisite modüllü High Performance Polyethylene (Hppe) Fibers AbSTRACTHigh performance polyethylene (HPPE) fibers exhibit high strength, high elasticity modulus as well as superior performance with their low density and high mechanical properties. HPPE fibers are generally produced by gel-spinning process. They display not only high abrasion and fatigue resistance, but also exhibit resistance to most chemicals. These fibers can float on the water with their low density, less than 1 g/cm 3 , and they are preferred in various marine applications due to their water and moisture resistant features as well as high mechanical properties. Furthermore, high energy absorption of these fibers allows for their use in ballistic products. Although their low melting temperature limits the application areas of HPPE fibers, today, it is possible to come across their end-use applications in many areas of technical textiles ...

“…Although the marine and oil industries have adopted several new polymer and carbon fiber technologies that might be applicable to WEC mooring designs, investigations into materials reliability testing are critically needed to determine if they meet mooring requirements. 37,38,39 Areas of concern include: rope construction, creep failure, fatigue, abrasion damage, wear resistance, chemical diffusion, along with the issues stemming from the interfacial contact between any steel component and the line mooring line. One notable concern for the WEC devices using steel construction is the effect of rust on mooring since decreases on fiber strength have already been reported for lines coated with rust particles.…”

This report considers and prioritizes the potential technical cost-reduction pathways for offshore point absorber wave energy converters designed for ocean resources. This report focuses on cost-reduction pathways related to the device technology rather than environmental monitoring or permitting opportunities. Three sources of information were used to understand current cost drivers and develop a prioritized list of potential cost-reduction pathways: a literature review of technical work related to offshore wave activated body point absorbers, a reference device that was developed through the DOE Reference Model project, and a webinar with each of four industry device developers. Data from these information sources were aggregated and prioritized with respect to the potential impact on the lifetime levelized cost of energy, the potential for progress, the potential for success, and the confidence in success. Results indicated the four most promising cost-reduction pathways include advanced controls, optimized structural design, improved power conversion, and optimized device profile. 4

This report considers and prioritizes the potential technical cost-reduction pathways for offshore oscillating water columns in both terminator and point absorber configurations designed for ocean resources. This report focuses on cost-reduction pathways related to the device technology rather than environmental monitoring or permitting opportunities. Three sources of information were used to understand current cost drivers and develop a prioritized list of potential cost-reduction pathways: a literature review of technical work related to oscillating water columns, a reference device that was developed through the Reference Model project and was augmented with data compiled from literature sources, and a webinar with each of three industry device developers. Data from these information sources were aggregated and prioritized with respect to the potential impact on the lifetime levelized cost of energy, the potential for progress, the potential for success, and the confidence in success. Results indicated the four most promising cost-reduction pathways include advanced controls, improved power conversion, an optimized structural design, and array optimization.
