If you want to perform machining and fabrication in-house, Atlas Fibre has thermoset composite sheets available. We have a large selection of in-stock thermoset and thermoplastic sheets at our facility in Illinois and our two partner facilities.
We also provide advice and resources to help you feel confident you’ve chosen the right material for your project. We want to work with you to reduce your project’s complexity and costs. Learn more about our selection of stock thermoset composite sheets and panels.
Thermoset plastic sheets are produced by pressing and curing prepreg materials into a flat sheet. The sheets are then cut and fabricated through several processes.
Sheet thickness depends on the number of plies in the sheet layup and can typically range from 0.005″ to more than 8″ in thickness. Overall dimensions are based on your project needs but traditionally full-size sheets come in three sizes, 36×48″, 48×48″, and 48×96″. Extra large sheets are also available by special request up to 48×120″. All sheets can be cut to size for your specific project.
Our thermoset composite panels comply with various standards, including NEMA and MIL-I. The materials can be tested to verify their performance properties.
The materials you need depend on your application and project. Some materials have better heat resistance than others and can withstand extreme heat or cold. If you’re working with cryogenic temperatures, for example, you must choose a material that can withstand below-freezing temperatures.
Certain materials offer better electrical insulation than others, too. For example, if you know you want to work with a canvas or linen phenolic and that you need electrical insulation, it’s important to choose either CE- or LE-grade phenolic as standard C and L grades don’t have adequate electrical insulation.
Two other factors to consider when choosing your material are flexural strength and impact resistance. These properties measure the material’s ability to withstand bending and impact forces applied to the thermoset. We can help you choose the right material based on your application, specifications, and other needs.
If you’re unsure which option is ideal for your project, you don’t have to determine which type of material is right on your own. We’ll partner with you and offer our expert advice and guidance.
