Abstract :
16 rigid plastic and composite materials were subjected to hydrostatic pressures experienced at a 6 km water depth (10000 psi) and the resulting dimensional changes were measured. The materials specimens included: PVC, CPVC, acrylic, polystyrene, polycarbonate, acetyl, ABS, LDPE, HDPE, UHMW PE, polypropylene, nylon 101, Teflon, Extren, hand lay-up fiberglass, and cured polyester resins. The slopes from strain/pressure graphs provided the authors with strain rates, which they used to calculate bulk moduli for all samples. The results provide data useful towards incorporating these plastic and composite materials into deep ocean designs
