采用橡胶压力成型（RPM）技术制备具有复杂几何形状的纤维增强塑料（FRP）构件。该技术基于匹配的模具组，其中模具由硬金属如钢制成，冲头由柔性橡胶类材料制成。柔性橡胶冲头加强并均匀地重新分配产品表面上的压力（操作压力和由于柔性橡胶冲头而产生的流体静压力）。在0.5 ~ 50 MPa的加工压力范围内，利用ANSYS分析了压力分布。扩展分析，找出压力分布均匀的橡胶模具的最佳硬度。为此，对炭黑用量从0到75份，增量为15份的NR硫化胶进行了分析，得到了2-、3-、5-和9-参数Mooney-Rivlin，1-、2-和3-阶Ogden，Neo-Hookean，1-、2-和3-阶多项式，Arruda-Boyce，使用第一、第二和第三阶Yeoh和Gent。炭黑填充量为45份的NR硫化胶效果最好。© 2007 Wiley Periodicals，Inc.应用聚合物科学杂志，2007年
Fiber reinforced plastic component (FRP) having complex shaped geometry is prepared by rubber pressure molding (RPM) technique. The technique is based on the matching die set, where the die is made of hard metal like steel and the punch from flexible rubber like materials. The flexible rubber punch intensifies and uniformly redistributes pressure (both operating pressure and developed hydrostatic pressure due to the flexible rubber punch) over the surface of product. The distribution of pressure was analyzed by ANSYS over a processing pressure of 0.5–50 MPa. The analysis was extended to find out the optimum hardness of rubber mold, where the pressure distribution is uniform. For this, analysis was carried out for NR vulcanizates where the loading of carbon black was varied from 0 to 75 phr with an increment of 15 phr. The strain energy density function of 2-, 3-, 5- and 9 parameter Mooney-Rivlin; 1st-, 2nd-, and 3rd order Ogden; Neo-Hookean; 1st-, 2nd-, and 3rd order Polynomial; Arruda-Boyce; 1st-, 2nd-, and 3rd order Yeoh; and Gent were used. 45phr carbon black loading NR vulcanizate shows best result. © 2007 Wiley Periodicals, Inc.
