The present invention relates to a composite material comprising a porous lead alloy containing from 0.7 to 1.0% silver or 0.1 to 1.0% calcium or 0.7 to 1.0% silver and 0.1 to 1.0% calcium and having its pores filled by a resin such as epoxy resin. The product has utility as a battery electrode and as a sound absorbing material.

A tube having holes formed at precise positions is obtained by preparing a tube in which a substantially black synthetic resin film portion (1) and a synthetic resin film portion (2) having a color other than substantially balck are formed alternately in its circumferential direction and then drilling the black synthetic resin film portion (1) by a laser beam (3).

A flexible oriented plastic sheet has a high tensile strength and is resistant to corrosion and highly resistant to splitting when penetrated by a pointed article. The flexible oriented sheet can be cut into desired shapes and sizes so as to be useful in a variety of applications, such as roofing batten bars and fencing materials, which require high resistance to splitting and fastener pull-throug...
