Abstract
A tool for shaping articles, such as tools for drawing,
bending, and vacuum shaping, e.g., for making automobile
body parts, has an active shaped surface part which is made
by casting a cement-bound material (15) directly against the
corresponding surface part of the model (12). This cement
bound material (15) has a coherent matrix comprising
A) homogeneously arranged inorganic solid particles of a size of from about 50 Å to about 0.5 µm, or a coherent structure formed from such homogeneously arranged particles, and
B) densely packed solid particles having a size of the order of 0.5 - 100 µm and being at least one order of magnitude larger than the respective particles stated under A), or a coherent structure formed from such densely packed particles, the particles B preferably being Portland cement particles.
A) homogeneously arranged inorganic solid particles of a size of from about 50 Å to about 0.5 µm, or a coherent structure formed from such homogeneously arranged particles, and
B) densely packed solid particles having a size of the order of 0.5 - 100 µm and being at least one order of magnitude larger than the respective particles stated under A), or a coherent structure formed from such densely packed particles, the particles B preferably being Portland cement particles.
Particles A are preferably ultrafine silica particles formed
by growth from vapour phase and are substantially densely
packed in the voids between the particles B. Particles A are
especially present in an amount of 10 - 30% by volume,
calculated on the combined volume of the particles A + B.
Composite material for forming the matrix typically compris
es Portland cement, ultrafine silica, water in low proportion,
and a concrete superplasticizer in high proportion, optionally
with additional bodies such as fibers, and is easily shape
able.
Preferably, matrix additionally comprises particles
which are of a strong material such as refractory grade
bauxite. and is reinforced. Tool is easy to make and has a
long useful life.
