摘要

The performance of a composite structure is often strongly dependent upon the connection between a composite component and a metallic end fitting. These connections have traditionally been made by bonding, pinning or riveting the fitting in place. The entrapped fiber joint, an alternative connection that incorporates the metal end fitting into the composite before final cure, is discussed and analyzed herein. The entrapped fiber connection is capable of carrying high axial tensile loads and is relatively easy to fabricate using the filament winding process. Nine geometric parameters that may impact the performance of the entrapped fiber connection were chosen for study. Analysis of these parameters, using fractional factorial experimentation and FEA, showed that only two of the nine parameters selected contributed significantly to the strength of the connection. By setting these parameters at their optimal levels the stress components in the connection were reduced from 38 to 75%.

ABSTRACTudThe purpose of this research is to obtain an optimal formulations of Black mulberry leaves dried noodle product by using Design Expert Application with Design Mixture D-optimal method.udThis research was done with two phases. The preliminary procedures research is to determine levels of antioxidant activity, chlorophyll content, and the levels of tannin that was contained in black mulberry leaves, the black mulberry leaf flour, a pare fruits, and pare flour. Primary research is to determine the best formulation by using a Mixture Design Expert Design D-optimal method, for a purpose is to optimized the Black mulberry leaf dry noodle. Responses in this studies are a chemical analysis response by using a crude fiber analysis and protein analysis. Physical response is water absorption. Sensory response are color, flavor, and odor.udBlack mulberry leaves dried noodles was made from wheat flour, black mulberry leaf flour, and pare flour, other materials such as an eggs, water, salt, and sodium bicarbonate, of the 16 formulations that has offered to produce an optimal formulation based on desirability which contains 39.69 Flour,14.25 Black Mulberry Leaves flour, 3.06 Pare fruit and flour amounted, and other materials are 30 water, 10 eggs, 2 salt, and 1 sodium bicarbonate. The formulation has been result by program 11,05 crude fiber content, 12.93 protein, 274.31 water absorption, 4,31 for color attribute, 3,87 for taste attribute, and 3,71 for aroma attribute.ududKeyword: Black mulberry leaf dried noodles, optimization.
