A transmission guide comprises a synthetic resin shoe supported by and integrally molded with a synthetic resin base by two-part molding. A guide length retaining mechanism, which can be formed by one or more protrusions on the back of the shoe and one or more cooperating recesses on the supporting surface of the base, retains the shoe against longitudinal movement relative to the base. A guide width retaining mechanism, which can be formed by projections on the edges of the shoe and cooperating holes formed in side walls extending from the supporting surface of the base, retains the shoe against widthwise movement relative to the base.

There is provided a synthetic resin member, having a screw formation portion and synthetic resin body. The screw formation portion has: a cylindrical metal portion having a first end and a second end, a female screw part being formed on the cylindrical portion; a release prevention portion formed at the first end; a flange portion formed at the second end, the flange portion having a first surface and a second surface opposite to the first surface; and a rotation prevention portion formed on the first surface. The synthetic resin body has: a body portion perpendicularly extending to have a third end and a fourth end, the body portion having a screw engagement portion perpendicularly penetrating the body portion. The cylindrical metal portion is inserted into the screw engagement portion. The release prevention portion is caulked with the third end of the body portion. The rotation prevention portion is engaged with the synthetic resin body at or near the fourth end of the body portion.

The invention belongs to the field of composite materials, relating to a molybdenum fibre reinforced resin concrete material. The molybdenum fibre reinforced resin concrete material comprises adhesive kinetosome and aggregate, wherein the adhesive kinetosome is a resin system formed by mixing composite resin, curing agents, diluents and flexibilizers, and the aggregate is of granite particles or gravel particles. The invention is characterized in that the molybdenum fibre reinforced resin concrete material also comprises molybdenum fibre. The raw materials are in following percentage by weight: 9-20% of the adhesive kinetosome, 77-90% of the aggregate and 0.1-3% of the molybdenum fibre. The molybdenum fibre adopts WEDM to cut and process scrapped molybdenum wires; after being cleaned, the molybdenum wire is cut into the molybdenum fibre with required length; and if the molybdenum fibre the surface of which is smooth is adopted, a corresponding processing method needs to be adopted to process the surface thereof so as to increase the bonding strength between the molybdenum fibre and resin and improve reinforcement effect. The composite material has favourable physical and mechanical properties; compared with no-fibre reinforced resin concrete material, the compression strength of the molybdenum fibre reinforced resin concrete material is improved by 15-30%. The molybdenum fibre reinforced resin concrete material can serve as favourable mechanical basic part material.
