Today we introduce the light-weight carbon fiber material plus aluminum gondola designed for the EXAMINE balloon-borne telescope. SPIDER is designed to gauge the polarization of the Cosmic Microwave The historical past radiation with unprecedented sensitivity plus control of systematics in search of the imprint of inflation: a period of rapid expansion in the early Universe. The necessities of this balloon-borne instrument put secured constrains on the mass budget with the payload. The SPIDER gondola was created to house the experiment and guarantee and support its operational and structural trustworthiness during its balloon-borne flight, and use less than 10% of the total size of the payload. We present a single construction method for the gondola by looking at carbon fiber reinforced polymer tubes concerning aluminum inserts and aluminum multi-tube joints. We describe the approval of the model through Finite Device Analysis and mechanical tests.
