Face guards (FGs) are protectors that allow for the rapid and safe return of athletes who are to play after sustaining traumatic facial injuries and orbital fractures. Current FGs require significant thickness to achieve sufficient shock absorption abilities. However, their weight and thickness render the FGs uncomfortable and reduce the field of vision of the athlete, thus hindering their performance. Therefore, thin and lightweight FGs are required. We fabricated FGs using commercial glass fiber-reinforced thermoplastic (GFRTP) and carbon fiber-reinforced thermoplastic (CFRTP) resins to achieve these requirements and investigated their shock absorption abilities through impact testing. The results showed that an FG composed of CFRTP is thinner and lighter than a conventional FG and has sufficient shock absorption ability. The fabrication method of an FG comprising CFRTP is similar to the conventional method. FGs composed of commercial FRTPs exhibit adequate shock absorption abilities and are thinner and lower in weight as compared to conventional FGs.

Dalam studi ini dilakukan analisis numerik tentang pengaruh perkuatan dengan pelat CFRP (Carbon Fiber Reinforced Polymer) terhadap tegangan tulangan tarik. Tegangan pada tulangan tarik ditinjau pada daerah sekitar perletakan balok sederhana dengan dua tumpuan. Untuk maksud tersebut serangkaian model numerik dipersiapkan dengan jenis tulangan yang berbeda. Dimana panjang penyaluran tambahan divariasikan 100mm dan 250mm. Tulangan yang digunakan adalah tulangan baja dan GFRP (Glass Fiber Reinforced Polymer). Hasil analisis menjelaskan bahwa perkuatan dengan pelat CFRP dapat meningkatkan kapasitas balok dimana tegangan yang diterima oleh tulangan tarik menurun. Disamping itu tulangan tarik GFRP juga terbukti efektif meningkatkan daktilitas balok beton bertulang.

W artykule przedstawiono obliczeniową analizę nośności dwuprzęsłowych belek ze zbrojeniem kompozytowym z włókien szklanych i węglowych (Glass Fiber Reinforced Polymer – GFRP; Carbon Fiber Reinforced Polymer – CFRP) opracowaną na podstawie wybranych wytycznych normowych: Fib Bulletin 40, japońskiej – JSCE, amerykańskiej – ACI 440 oraz kanadyjskiej – ISIS z wynikami wybranych badań doświadczalnych. Głównym celem pracy jest określenie wpływu redystrybucji momentów przy obliczaniu nośności belek dwuprzęsłowych. Wyniki uproszczonej analizy obliczeniowej (bez wpływu redystrybucji momentów) pozwoliły porównać różne podejścia normowe oraz określić poziom zgodności wyników obliczeniowych z wynikami doświadczalnymi. W ten sposób można oszacować zakres bezpieczeństwa nośności na zginanie określony wpływem redystrybucji momentów względem wyników badań doświadczalnych.

This work aims to perform a systematic investigation on the crystallization behavior and morphologies of carbon and glass fiber reinforced PEEK. The nonisothermal and isothermal crystallization behavior was investigated by differential scanning calorimetry (DSC). The resultant morphologies were assessed by wide angle X-ray diffraction (WAXD), small angle X-ray scattering (SAXS), and polarized optical microscopy (POM) to provide details on spherulitic level, crystalline structure at unit cell, and lamellar levels. It was found that the crystallization ability of carbon fiber filled PEEK was better than that of neat PEEK, while the behavior of glass fiber filled PEEK was in an opposite trend. The incorporation of carbon fiber (or glass fiber) led to a looser packing of the unit cell or a less crystal perfection of PEEK but did not change its crystal form as well as its long period of lamellae. The isothermal crystallization kinetics was analyzed by the Avrami model, suggesting that the crystallization mechanism of carbon fiber filled PEEK was different from that of neat PEEK and its glass fiber filled composites. Nevertheless, the POM results showed that fiber-induced transcrystallization in PEEK matrix was not evidenced for either carbon or glass fiber filled PEEK. Finally, the effect of carbon and glass fiber on the crystallization of PEEK matrix was discussed to some extent.
