ジャーナル フリーUnsaturated polyester molding compounds as BMC (bulk molding compound) are generally molded without preheating i.e. under the room temperature. However, the injection molding with preheating can be expected to have such advantages that the curing time is shorter and that the injection pressure is lower. Moreover, in regard to the breakage of glass fiber during flow of BMC into cavity, it is desirable that the viscosity of BMC is low. Such effects can be expected by preheating. Then in this paper, nozzle injection pressure, cavity pressure and injection plunger displacement have been measured in case of preheating BMC. Besides, the flexural strength of injection molded parts of preheating BMC has been investigated. The main results obtained are as follows : 1) The injection molding of preheating BMC made possible to mold in reasonably lower injection set pressure than that of non-preheating. In case of preheating BMC, the maximum pressure in cavity became lower, the curing time became shorter and the locational difference of pressure in cavity was reduced. 2) Preheating BMC made the flexural strength of injection molded parts higher.抄録全体を表示PDF形式でダウンロード (2450K) -

ジャーナル フリーThe key point of the present investigation is to consider the fiber anisotropy in thermal conductivity, which remains unclarified. An analytical procedure similar to the calculation of the longitudinal shear modulus is employed here. Thermal conductivities of CFRP-UD and Epoxy resin are measured by using an apparatus based on the infra-red radiation method. Accuracy of these experimental data is guaranteed. Thermal conductivities of carbon fiber itself which can hardly be measured directly are estimated by combining these analytical and experimental results. Not only in the case of elastic moduli but thermal conductivity, it is clarified that the carbon fibers are highly anisotropic. There can be observed a considerable difference of analytical results of thermal conductivity for two idealized fiber packing arrangements at large Vf to the same extent as the case of the longitudinal shear modulus.抄録全体を表示PDF形式でダウンロード (4121K) -
