MIL-HDBK-17-3F Volume 3,Chapter 8 Supportability 8.2.3.3 Product forms A detailed description of available composite product forms can be found in Section 2.5. The goal when repairing a composite part is to return it to its original performance capability while in- curring the least cost and weight gain.Therefore,the ease of repairing different product forms should be taken into consideration when selecting the material system.Figure 8.2.3.3 shows the relative ease of repairing various product forms. 8.2.3.4 Adhesives Table 8.2.3.4 provides descriptions of issues for use of adhesives in repairs. 8.2.3.5 Supportability issues Table 8.2.3.5 offers a list of Material Support issues for your consideration. 8.2.3.6 Environmental concerns Health and safety:There are recognized hazards that go with advanced composite materials. Knowing about these hazards,one can protect oneself and others from exposure to them.It is important to read and understand the Material Safety Data Sheets (MSDS)and handle all chemicals,resins and fibers correctly.Refer to SACMA publication "Safe Handling of Advanced Composite Materials"for addi- tional information(Reference 8.2.3.6). Disposal of scrap and waste:When selecting materials,consideration must be given to the dis- posal of scrap and waste.Disposal of scrap and waste should be specified under federal,state and local laws.See Section 8.2.5.6 on how to dispose of uncured materials.
