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.

Generally, the moisture absorbed in the composites plasticizes the resin. And it makes the composites expansion in volume and generates the cracking at the same time, So, the fracture is often generated in the composites by those reason. Therefore, in this study, the change of mechanical properties due to the moisture-absorption for the carbon fiber reinforced composites in comparison with basalt fiber and glass fiber reinforced composites are investigated. The specimens for the carbon, basalt, and glass fiber reinforced composites manufactured with the ASTM standard. The specimens immersed in distilled water at 80°C during 100 days and the coefficient of moisture was measured in according to the Fick's law. In addition, after drying process, the humidity-absorbed specimen under 80°C for 1 day, the recovery rate was measured. As a result, the coefficient of moisture-absorption of carbon fiber reinforced composite material was the lowest at approximately 3 % because the interface coherence with the fiber and resin are the most strong. Also, after drying process, the recovery rate was 20 percent higher than the others.
