Maximum 200 words) The main goals of this research program at UTSI were: 1) to produce low cost carbon fibers and 2) to develop specific carbonbased material technologies to meet current and future high performance fiber-reinforced composite needs of FTA and other organizations. UTSI has been carrying out the relevant research programs since it received the carbon fiber spinning technologies an...

Potassium methyl siliconate (PMS) was investigated as a new nano modifier of wood fiber and wood flour to improve the compatibility between the fiber/flour and the plastic matrix in fiber reinforced plastic composites. Before injection molding, bleached and brown pulp fibers and mixed species wood flour were pretreated in PMS solutions. The morphology of the treated and untreated fiber and flou...

It has been established that carbon plastics are increasingly used in various industries as structural materials. By the set of their properties, outperform steel, cast iron, alloys non-ferrous metals. However, application these materials for parts machine friction units is still limited due to difficult operating conditions modern tribosystems. This work aims conduct a comprehensive experiment...

Carbon fiber reinforced plastic (CFRP) was used to adhesively reinforce Chinese fir (Cunninghamia lanceolata) wood specimens. This study examined the flexural static and creep performances of CFPR-reinforced wood composites that had been subjected to changes in moisture and stress levels. The major findings were as follows: 1) the cyclic creep was slightly lower for those specimens subjected to...

Purpose Many additively manufactured parts suffer from reduced interlayer strength. This anisotropy is necessarily tied to the orientation during manufacture. When individual features on a part have conflicting optimal orientations, unavoidably compromised. paper aims demonstrate strategy in which can be functionally separated into “co-parts” are individually aligned an orientation, selectively...

Fiber-metal laminates (FMLs) such as Kevlar reinforced aluminum laminate (ARALL), 18 Carbon reinforced aluminum laminate (CARALL), and Glass reinforced aluminum laminate 19 (GLARE) offer great potential for weight reduction applications in automobile and aerospace 20 construction. In order to investigate the feasibility for utilizing such materials in the form of 21 laminates, sheet hydro-bulgi...

This work presents a PCD (polycrystalline diamond) end mill with a new staggered structure for the milling of CFRP (carbon fiber reinforced plastic). The magnitude and direction of cutting force is decreased and changed by side-edge re-configuration of the structure. The flute and insert pocket of the staggered PCD end mill are designed considering the tool’s stiffness and welding process. The ...

Based on the electromagnetic induction heating method, and curing of Carbon Fiber Reinforced Polymer (CFRP) have advantages high energy utilization no pollution. However, in process, both material weaving structure mold can affect temperature field. Therefore, this study, an finite element analysis model for CFRP circular tubes was established based equivalent thermal characteristics CFRP. The ...

This study deals with the optimisation of hybrid composite drive shafts operating at subcritical or supercritical speeds, using a genetic algorithm. A formulation for the flexural vibrations of a composite drive shaft mounted on viscoelastic supports including shear effects is developed. In particular, an analytic stability criterion is developed to ensure the integrity of the system in the sup...
