In this paper, composite and hybrid materials were prepared using the hand lay-up method, with carbon, glass, Kevlar fabrics as reinforcing epoxy a matrix. The tensile test was performed to determine optimal ratio of resin in carbon fabric/epoxy, glass fabric/epoxy composites terms properties. It found that properties impregnate used fabric, fabric around 45%wt, 3%wt, 30 %wt, respectively. effe...

Abstract Glass fiber is an important component of resin composites and greatly affects the properties materials. UV-cured pipe rehabilitation lining materials prepared by hand lay-up process using glass fibers with different areal densities weaving types were studied in this paper. Their thermal stability mechanical properties, such as flexural strength, modulus, tensile studied. The results sh...

Tujuan dari penelitian ini untuk mengetahui kekuatan sifat mekanik dan fisik komposit sandwich carbon fiber core kayu balsa dengan variasi jumlah layer skin (2, 4, 6 ), orientasi serat (0°/90°) ketebalan 5 mm. Matriks yang digunakan adalah resin epoxy bakelite EPR 174 manufaktur menggunakan metode hand lay-up vacuum bagging , dimana standar spesimen mengacu pada ASTM D790 pengujian bending D611...

In this study, composite materials are produced, placing unidirectional carbon fiber reinforcements with 12 filament numbers in a polyester matrix to form one, two, and three layers at room temperature through the hand lay-up method. The samples prepared from plates help of mold line direction angle by standards. tensile, three-point bending, falling weight low-speed impact strength values were...

The fiber-metal composites made of aluminum sheets and glass fibers reinforced with a polyester resin as the matrix were studied. prepared by hand lay-up method. Some aspects manufacturing affecting composite behavior considered. In particular, influences arrangement layers their number on mechanical physical properties ten different compositions investigated. addition two densities tensile mod...

This research is aimed at seeing how different stacking sequences and chemical treatments impact the mechanical characteristics of ramie–hemp composites. Hand-lay-up procedures were used to create a blend woven ramie hemp fibers. The was treated with diluted 6% sodium hydroxide (NaOH) solution compare properties preserved unpreserved hybrid According findings, tensile composites are better in t...

Guided by a culturally-informed illness representation self-regulation model (CIRSRM), this study analyzed the relations among 223 Asian Americans’ lay beliefs about depression, enculturation to Asian values, and their likelihood of seeking professional help for depression. Participants’ lay beliefs were assessed through an analysis of written responses to open-ended questions about depression....
