Meningkatnya penggunaan pipa komposit untuk berbagai keperluan seperti pada industri lepas pantai di mana membutuhkan ketahanan korosi yang tinggi, rasio kekakuan terhadap berat tinggi dan rendahnya biaya pemeliharaan menjadi sangat penting. Penelitian ini bertujuan investigasi sifat mekanik dengan menggunakan metode bladder compression molding tekanan 7 bar, temperatur 120ºC ruangan. Menggunak...

With the popularity of 5 G, there is an increasing request for a light, high-performance, and stable structure wireless communication. To solve problems delamination cracking its own heavy weight conventional microstrip antenna, this study used ultra-high molecular polyethylene (UHMWPE) filament tows purple copper as raw materials to prepare 3D woven hollow antenna preforms on common loom. Usin...

Micro-sized Al2O3-modified carbon fiber hybrid reinforced polymer composites (CFHRP) were prepared using the vacuum-assisted resin transfer molding (VARTM) process, and friction wear tests performed on an MRTR-1 multifunctional tester to study effect of surface doping with trace amounts Al2O3 its content tribological properties composites. The morphology composite material was characterized a t...

Kenaf fiber-polyester composites incorporated with powdered activated carbon (PAC) were prepared using the vacuum-assisted resin transfer molding (VARTM) process. The product demonstrates the electromagnetic interference (EMI) shielding function. The kenaf fibers were retted in a pressured reactor to remove the lignin and extractives in the fiber. The PAC was loaded into the freshly retted fibe...

Experimental and theoretical approaches are studied via the first-ply failure strength on anti-symmetrically laminated composite elevated floor plates with various length-to-depth ratios, aspect ratios, and optimal fibre orientations subjected to central point loads. Optimal angle-ply orientations of anti-symmetric [θ/ − θ . . .]−S laminated composite plates designed for maximum stiffness were ...

Hybridization is an important application in obtaining the multi-functionality to combine best properties of each reinforcing element makes up composite. In this study, hybrid composites and uniform were fabricated using carbon, aramid, intraply carbon/aramid weaves with two different production methods (vacuum-assisted resin transfer molding process vacuum bagging process). The mechanical prod...
