评估结构复材成本和设计的新型COMPAREM (TM)程序
By www.carbonfiber.com.cn
COMPAREM (TM)程序是为工程师、项目经理开发的一个相对比较复杂的程序。COMPAREM
(TM)程序是发展的比较成熟的一项技术，主要用途是对材料/设计可选方案进行了评估，在几分钟之内就可选出最佳适合方案。
复合材料结构部件
材料属性、材料价格、部件设计、部件属性以及部件成本之间的关系非常复杂，常常引起人们的误解，尤其是用于结构复合材料应用领域时。对于这些应用领域，最低价格材料不一定总能生产出生产成本最低的结构部件，最轻的部件不一定总能使用比重最低的材料才能模塑成形，传统材料加工工艺无法发挥作用。加工工艺必须易于使用，因此，必须对更多可选材料和设计方案进行评估。
开发COMPAREM (TM)程序便是为了符合这一需求。COMPAREM
(TM)程序是为工程师、项目经理开发的一个相对比较复杂的程序。主要用途是对材料/设计可选方案进行了评估，在几分钟之内就可选出最佳适合方案。
第一步是来选择COMPAREM
(TM)程序中描述新应用领域的设计种类（如有棱角部件、U型槽等）。然后输入当前状况的信息或优选材料和部件尺寸大小。接下来，输入材料信息、供选部件的尺寸。程序将自动计算生产部件的每份材料/设计组合的硬度、强度、重量、材料成本以及固化时间。然而，不同部件的性能差别非常大。一些部件的硬度可能会超过当前部件的硬度或强度，其它部件则可能不符合标准要求。部件性能存在如此大的差异，再进行成本对比则毫无意义了。
第二步是均化各部件之间的性能，使用目前部件的强度和硬度作为基准。修改可选部件的适宜尺寸，使其至少可承受目前部件的重量。COMPAREM
(TM)程序使这一工艺更简易。每一次改变，部件的硬度和强度自动更新。
所有部件的性能相同后，然后对其重量、材料成本和固化时间进行比较。为了更深入的分析与发展，时间和资源是对比的重点。
COMPAREM
(TM)程序的工作流程为：选择合适的设计方案类型、输入不同部件所用材料和设计数据、对比不同部件的性能、均化各部件的性能、对比均化性能后各部件的重量和成本、对比不同设计类型生产的部件、对比均化性能后各部件的重量和成本。
结论
商业用结构复合材料部件是一个不断增长的市场。然而，如需在这一市场中具有竞争力，选择材料和设计部件时，思想要开放。COMPAREM
(TM)程序是发展的比较成熟的一项技术。使用COMPAREM (TM)程序在几分钟之内便可选择出复合材料结构部件最佳适用方案。

The relationship between material properties, material price, part design, part
performance and part cost is complex and often misunderstood. This is especially
true for structural composite applications. For these applications the lowest
priced material does not always produce the lowest cost part, the lightest part
is not always molded from the material with the lowest specific gravity and the
traditional material selection process does not work. A more sophisticated
selection process is required. A process that integrates and quantifies the key
factors, then helps identify the best material with the optimum design, at the
lowest cost. The process must also be easy to use, so many more material and
design options can be evaluated.
The COMPAREM (TM) program was developed for this purpose. It is a sophisticated
comparison program that can be used by engineers and program managers as well as
buyers. Several material/design combinations can be evaluated and the best
candidate(s) selected in a matter of minutes --- instead of hours.
The first step is to select the design category in the COMPAREM (TM) program,
that describes the new application (i.e. Ribbed Part, “U” Channel, etc.). Then
enter the information on the current or preferred material and part dimensions.
Next, enter the material information and dimensions of the competing parts. The
program automatically calculates the part’s stiffness, strength, weight,
material cost and cure time for each material/design combination. However, the
performance of the parts can vary widely. Some of the parts may exceed the
stiffness or strength of the current part, while others may fall short. With
such a difference in part performance, a cost comparison would be meaningless.
The next step is to equalize the performance of the parts, using the strength
and stiffness of the current part as the baseline. Modify the appropriate
dimensions of the competing parts until they are at least as stiff and can carry
the same loading* as the current part. The COMPAREM (TM) program makes this
process easy. With each change, the stiffness and strength of the part is
automatically updated.
Once the performance of all the parts is equivalent, then they can be compared
--- for weight, materia cost and cure time. Time and resources are then
concentrated on the best candidate(s), for further analysis and development.
The following example demonstrates how the COMPAREM (TM) program works and how
it is used. 1.Select the Appropriate Design Category; 2. Enter Material and
Design Data for the Different Parts; 3. Compare the Performance of the
Different Parts; 4. Equalize the Performance of the Parts; 5. Compare the
Weight and Cost of the Equivalent Parts; 6. If Possible, Compare a Part from a
Different Design Category; 7. Compare the Weight and Cost of all the Equivalent
Parts
Structural composite parts, for commercial applications, is a growing market.
However, to be competitive in this market requires an open mind and a more
sophisticated process of material selection & part design. COMPAREM (TM)
provides that higher level of sophistication. In this example, the lowest priced
material did not produce the lowest cost part and the lightest part was not
molded from the material with the lowest specific gravity. In a different
situation, the best material/design may be very different. Now it is possible to
find out in a few minutes, with the COMPAREM (TM) program.
