3D printing with concrete is a promising new method for rapid, low cost construction. The flexural strengths reinforced/unreinforced and printed/cast Warren trusses were tabulated the failure mechanisms reported. types of reinforcement used rebar(basalt steel), mesh (basalt aramid). effect loading geometry speed was measured basalt aramid composite, respectively. Due to expected variation in fl...

One of the key challenges in additive manufacturing plastic goods using Fused Filament Fabrication (FFF) technology is to ensure their strength. The low strength polymer materials and distinct anisotropy mechanical properties limit use 3D printing as an alternative traditional small-scale production technologies. most promising solution goal increasing printed application continuous fiber reinf...

Waru tree bark fiber (hibiscus tiliceus) has potential as a natural composite reinforcement, but further research is needed by focusing on the woven model strength of waru material. The problem to be studied "The Effect Model Bark Fiber Weaving Tensile Strength Composites". specific objective this study was analyze effect hibiscus tensile in terms ultimate strength, strain, and modulus elastici...

A research has been conducted in the present study to investigate the effect of hole configuration on tensile strength of lontar fiber-reinforced composites. The lontar fiber-reinforced composites used in this study were produced by hand lay-up process. The lontar fiber-reinforced composites consist of short random fiber of 5 cm that contains 32% of nominal fiber volume as the reinforcement and...

The advancement in science and technology has led to luffa sponge (LS) being widely used as a natural material in industrial application as its polyporous structure and light texture. In order to enhance the utility of LS fibers as the reinforcement of lightweight composite materials, this study investigate its water absorption, mechanical properties, anatomical characteristic and thermal perfo...

A framework for stochastic modelling and optimization of materials with engineered microstructures is presented. Numerical methods for solving problems with short-fiber inclusions are discussed. Addition of fiber reinforcement has been shown to improve the performance of various materials in a number of applications. The response of fiber reinforced concrete under tensile stress is dependent up...

Ceramic matrix composites usually utilize carbon or ceramic fibers as reinforcements. However, such often expose a low ductility during failure. In this work, we follow the idea of reinforcement concept reinforced by refractory metal to reach pseudo ductile behavior Tungsten and molybdenum were chosen in SiCN manufactured polymer infiltration pyrolysis process. The investigated with respect mic...

Carbon Fiber Reinforced Polymer (CFRP) laminates are applied to many aerospace structures. For these laminated CFRP structures, it is quite difficult to detect internal damage such as delamination, matrix cracks, and local fiber breakages. Carbon fibers are adopted as reinforcement in CFRP and it is an excellent electric conductor at the same time. The carbon fiber has been used as a strain sen...
