TARIFNAME SABITLENMIS GÜÇLENDIRICI TEKSTIL KUMAS VE BUNUN ÜRETIM YÖNTEMI Teknik Alan Bu bulus, havacilik, savunma sanayi, medikal, denizcilik ve otomotiv basta olmak üzere tüm endüstriyel alanlarda yapisal ve görsel malzeme olarak kullanilmak üzere gelistirilen ve en az tek yönlü güçlendirici elyaftan mamül iplik ile olusturulan dokuma bez yapilarin, eriyebilen termoplastik ip (meltable thermoplastic yarn) ile sabitlenmesini saglayan üretim yöntemi ile ilgilidir. DESCRIPTION FIXED REINFORCEMENT TEXTILE FABRIC AND ITS PRODUCTION METHOD Technical Area This invention is mainly used in aerospace, defense industry, medical, marine and automotive. To be used as a structural and visual material in all industrial areas, including with yarn made of at least one-way reinforcing fiber The woven fabric structures formed are made of fusible thermoplastic yarn (meltable It is related to the production method that allows it to be fixed with thermoplastic yarn).

Bulusun Önceki Uygulamalari Kompozitler, termoset ve termoplastik olarak iki ana kategoriye ayrilir. Termoset kompozitler, termoset reçine emdirilmis güçlendirici elyaflardan mamül ipliklerden olusan yapilardir. Termoplastik kompozitler, termoplastik reçine emdirilmis güçlendirici elyaflardan mamül ipliklerden olusan yapilardir. Prior Applications of the Invention Composites are divided into two main categories as thermoset and thermoplastic. Thermoset composites made of reinforcing fibers impregnated with thermosetting resin They are structures made of threads. Thermoplastic composites, thermoplastic resin They are structures consisting of yarns made of impregnated reinforcing fibers.

Kompozitler günümüzde hafifletme, emisyon degerleri azaltmasi, korozyona karsi direnci gibi özellikleri nedeniyle çok popülerdir. Today, composites are used to reduce emissions, reduce emissions, and resist corrosion. It is very popular due to its properties such as resistance.

Günümüzde kompozit sektöründe kullanilan güçlendirici elyaf içeren tekstillerin sabitlenmesinde kullanilan reçine; sivi ya da toz olarak uygulanmaktadir. Elde edilen yari mamül tekstil ürünü daha sonra isi ve/veya basinçla sekillendirme gibi üretim metotlariyla son ürün olan kompozit malzemeye dönüstürülmektedir. Today, textiles containing reinforcing fibers used in the composite industry resin used for fixing; It is applied as a liquid or powder. in hand The semi-finished textile product is then formed by heat and/or pressure. It is converted into composite material, which is the final product, by production methods.

Termoset ve termoplastik kompozit üretmek için gelistirilen güçlendirici tekstilleri sabitlemek amaciyla poliamidler (PA) (poliamid 6 (PA6), poliamid poliarilenetersülfon, poliolefinler (polietilen (PE), polipropilen (PP) gibi), 9081.106 poliimid (PI), poliesterler tercihen polietilen teraftalat (PET) veya polibutilen teraftalat (PBT) gibi, polieter eter keton (PEEK) gibi iplikler kullanilabilmektedir. Reinforcer developed to produce thermoset and thermoplastic composites polyamides (PA) for fixing textiles (polyamide 6 (PA6), polyamide polyaryleneethersulfone, polyolefins (such as polyethylene (PE), polypropylene (PP)), 9081.106 polyimide (PI), polyesters preferably polyethylene terephthalate (PET) or polybutylene yarns such as terephthalate (PBT) and polyether ether ketone (PEEK) can be used.

Sabitleme prosesinde toz ve sivi halindeki reçine, güçlendirici elyaf içeren tekstil üzerine manuel veya otomatik yöntemler ile uygulanabilmektedir. Özellikle toz uygulamasi; reçinenin dagiliminda homojenizasyon problemi, optimum hammadde kullanma zorlugu, üretim esnasinda olusan atigin fazla olmasi ve üretilen kompozit malzemenin mukavemet degerlerinde degiskenlik olmasi gibi durumlara neden olmaktadir. In the fixing process, resin in powder and liquid form, textile containing reinforcing fiber It can be applied by manual or automatic methods. especially dust application; homogenization problem in the dispersion of the resin, optimum difficulty in using raw materials, excessive waste generated during production and such as variability in the strength values of the produced composite material. cause situations.

Güçlendirici elyaf içeren tekstillerin sabitlenmesinde kullanilan üretim yöntemi kesikli veya sürekli proseslerle yapilabilmektedir. Hem kesikli hem de sürekli yöntemde, toz ve sivi reçine beslemesinin otomatik olmasi durumunda bile reçine/ güçlendirici elyaf orani kullanilan reçine miktarinin oldukça düsük olmasi sebebiyle istenilen hassasiyette uygulanamamaktadir. Birim alanda kullanilan reçine miktarinda varyasyonlar olusmaktadir. Production method used for fixing textiles containing reinforcing fibers It can be done in batch or continuous processes. Both intermittent and continuous method, even if powder and liquid resin feeding is automatic The resin/reinforcing fiber ratio is very low in the amount of resin used. Therefore, it cannot be applied with the desired sensitivity. used per unit area There are variations in the amount of resin.

Bulusta kullanilan dokuma terimi, çözgü ve atki ipliklerinin kesismesinden olusan bir sistem veya desen olarak tanimlanmaktadir. Iki boyutlu dokumalarin temelde üç türü bulunmaktadir: bezayagi, dimi ve saten. Diger tüm dokuma türleri bunlarindan bir veya birkaçinin türevidir. The term weaving used in the invention is derived from the intersection of the warp and weft threads. It is defined as a system or pattern that occurs. two-dimensional textures There are basically three types: plain, twill and satin. All other types of weaving derivative of one or more of them.

Bulusta kullanilan dokuma islemi terimi, üretilen dokuma kumasta benzer malzemeden iki ipligin birbirlerine dik açi yaparak birbiri üzerinden geçecek sekilde üretim yöntemi veya sürecidir. Çözgü iplikleri veya uçlari kumas boyunca uzanirlar, atki iplikleri ise yatay yönde uzanirlar. Dokuma islemi, makine veya el dokuma tezgahlarinda veya elde farkli yöntemlerle gerçeklestirilir. 9081.106 Bulusta kullanilan bezayagi (plain) dokuma terimi, üç temel dokuma türü olan bezayagi, saten ve dimi dokumadan biridir. Her bir atki ipligi, çözgü ipliklerinin sirayla bir üzerinden bir altindan geçer. The term weaving process used in the invention is similar to the woven fabric produced. two yarns of the material will pass over each other by making a right angle to each other. It is a production method or process. Warp threads or ends along the fabric they extend, the weft threads extend in the horizontal direction. Weaving, machine or hand It is carried out on weaving looms or by hand with different methods. 9081.106 The term plain weaving used in the invention refers to three basic types of weaving. It is one of plain, satin and twill weave. Each weft thread is made up of warp threads. passes over and under one by one in turn.

Bulusta kullanilan dimi dokuma terimi, temel bir dokuma türüdür, karakteristik özelligi çözgü yönünde sasirtmali bir dizi atlamadan olusan çapraz hatlara sahip olmasidir. Çözgü yüzeyli dimi dokuma, çözgü ipliklerinin çapraz desen etkisi yarattigi bir tür dokumadir.

Özetle, yeni gelistirilen yöntemle reçine besleme homojenizasyonu miktarsal olarak üretime baslamadan önce elde edilmektedir. Production used for fixing textiles containing reinforcing fibers In the method, batch or continuous methods can be used. Both The main principle used in the method is the yarn made of reinforcing fiber. thermoplastic yarn of the resin used to fix the fabric produced in its form and at a temperature above its softening or melting point. pressure (0-100 bar) and thus the resin bonds to the reinforcing fibers. allows it to penetrate. Temperature and pressure from 0.01 minutes to 60 minutes After the application within a specified period of time between is being implemented. Depending on the nature of the polymer, the cooling process is pressureless or pressured. It can be applied under (0-100 bar). Cooling temperature, glassy transition of the resin It is below the temperature (Tg). The temperature range that can be used in the cooling process It is between °C and 200°C. Applications in the state of the art, It cannot ensure that the resin is homogeneously dispersed into the fibers and It does not give a precise resin distribution. On the other hand, within the scope of the invention In the method carried out, since the resin is used in the form of a rope, The resin/reinforcing fiber ratio can be precisely adjusted. In summary, new With the developed method, resin feeding homogenization is quantitatively increased to production. obtained before starting.
