Carbon fiber depends on its remarkable intensity / weight is compared and in aviation project application domain is welcomed. Although if fiber enhances plastic intensity respect,people is rising carbon fiber composite material,made a lot of effort, but considered pair of fiber orientaton only however optimize. Now, the researcher of college of Tokyo grain industry people used a kind of new design method to optimize fibrous ply and orientaton, reduced thereby enhance plastic weight, the plane that pledges gentlier for development and car open up road. Carbon lives to all biologic and character is crucial, because it is the foundation of all and organic element, formed the basis of all life then. Although this itself makes a person impressive, but, it is better to give the intensity that compares steel and tigidity as development and the carbon fiber with lighter weight, in recent years, the domain such as aerospace and civil engineering appeared a lot of surprising new application, this makes carbon fiber replaces rolled steel to be applied in the high-powered product such as plane, racing bicycle and athletic equipment. Carbon fiber forms composite material with other data union normally, a kind of among them composite material is carbon fiber increases plastic (CFRP) , it is mixed with its high tensile strength, tigidity intensity / weight is compared and outstanding. Because demand is big, accordingly, researcher people began multinomial research, with period the strength that increases CFRPs, and, they use most time in a design that the name directs for “ fiber (Fiber-steered Design) on the special technology research of ” , this technology can optimize fiber orientaton, increase strength thereby. But the design with “ oriented fiber (Fiber-steered Design) the method is not without defect, it can optimize fibrous orientaton only, but maintain fibrous ply however changeless, this affected mechanical to CFRP performance greatly make full use of. And one kind also allows those who optimize fiber ply to decrease serious means to be considered rarely however at the same time. College of industry of ” Tokyo grain is dedicated the say of Dr. Ryosuke Matsuzaki that studies at composite material. For this, dr. Matsuzaki and the colleague Yuto Mori that its are in college of Tokyo grain industry and Naoya Kumekawa together, formulated a kind of new design method, namely according to the position in composite material structure, will optimize fibrous orientaton and ply at the same time, this makes they can contrast the weight that waits for model of ply linear lamination, will reduce the weight of CFRP, do not affect its intensity at the same time. Publish in " Composite Structures " a medium new discovery that studies the paper introduced them. Their method includes 3 measure: Preparation, iteration and correction process. In planning a course, use finite yuan of method (FEM) undertake preliminary analysis, in order to decide number of plies, press model and the fiber that contain ply change model through a kind of linear layer oriented design (Fiber-steered Design) will undertake qualitative weight is evaluated. Iteration process is a basis advocate stress direction decides fiber orientaton, and with theory of “ great stress ” comes iteration computation ply. Correction process is to be aimed at producibility to undertake correction, this includes two steps: First, the ” of “ foundation fasciculus that founds a reference in the area that needs to increase strength; Next, distributing according to fasciculus consulting the form of bundle of two side arranges fasciculus, decide with this eventually orientaton and ply. Compare with the methodological photograph that optimizes fiber orientaton only, this kind optimizes the method of fibrous orientaton and ply at the same time, realized 5% above decrease serious effect and higher load to deliver efficiency. Researcher people feel special excitement to these results, expecting to will adopt the method that implements oneself henceforth, will reduce the weight of traditional CFRP component further.
