in the present research work, the flexural modulus and strength of glass fiber-epoxy resin and carbon fiber-epoxy resin composites have been enhanced through fiber tension during curing of the polymeric resin. this study showed that the tension applied on the fibers increased the flexural modulus of the glass-epoxy composites up to 12% and the flexural strength up to 19%. the flexural modulus a...

Hybrid fiber-reinforced polymer composites comprised of glass and steel fibers in a resin matrix have been shown to increased strength energy dissipation compared conventional composites. However, methods for simulating the mechanical behavior combinations hybrid yet be advanced. In this study, non-hybrid with off-axis were manufactured extracted coupons subjected half-cyclic tensile testing. T...

In this study, effect of MAPE (maleic anhydride polyethylene) as the compatibilizer on the mechanical properties of wood-flour polyethylene composites has been investigated by using Dynamic Mechanical Analysis (DMA). Composites were made at 25% and 50% by weight fiber contents and 1% and 2% compatibilizer respectively. Controls were also made at the same fiber contents without the compatibilize...

Hybrid composites have been drawing the attention of researchers in field because their high flexibility to tailor properties through fibers hybridization. The behavior hybrid is dependent on nature, amount, processing parameters, among other each reinforcing fiber and polymeric resin. glass fiber/vegetable reinforced polymer combine performance synthetic with ecological appeal vegetable ones. ...

The present study explores the physical-mechanical and tribological properties of hybrid wood fiber rockwool-reinforced asbestos-free resin-based friction materials. We developed brake composites with different contents (wood rockwool fiber) at a total fixed loading 30%. Then, were investigated on physical, mechanical, according to industry standards. results show that, increase in fiber, densi...

Natural composites exhibit exceptional mechanical performance that often arises from complex fiber arrangements within continuous matrices. Inspired by these natural systems, we developed a rotational 3D printing method that enables spatially controlled orientation of short fibers in polymer matrices solely by varying the nozzle rotation speed relative to the printing speed. Using this method, ...

Resin transfer molding of an inorganic polymer binder was successfully demonstrated in the preparation of ceramic fiber reinforced engine exhaust valves. Unfortunately, in the preliminary processing trials, the resulting composite valves were too brittle for in-engine evaluation. To address this limited toughness, the effectiveness of a modified fiber-matrix interface is investigated through th...

Carbon nanotubes (CNTs) have attracted a great deal of interest in the development of high-performance engineering composites, due to their exceptional physical, mechanical, electronic and thermal properties. Incorporation of CNTs into polymer has shown great improvements in the functional property, however, the enhancement of the mechanical property was insignificant compared with that of micr...
